Abstract

GeoDCAT-AP is an extension of the DCAT application profile for data portals in Europe ([[[DCAT-AP-3]]]) for describing geospatial datasets, dataset series, and services. Its basic use case is to make spatial datasets, dataset series, and services searchable on general data portals, thereby making geospatial information better findable across borders and sectors. For this purpose, GeoDCAT-AP provides an RDF vocabulary and the corresponding RDF syntax binding for the union of metadata elements of the core profile of ISO 19115:2003 [[ISO-19115]], those defined in the framework of the INSPIRE Directive [[INSPIRE-DIR]] of the European Union and those defined in the Technical Guidance for the implementation of INSPIRE dataset and service metadata based on ISO/TS 19139:2007 [[INSPIRE-MD]].

Main Entities

The main entities are those that form the core of the Application Profile. The properties and their associated constraints that apply in the context of this profile are listed in a tabular form. Each row corresponds to one property. In addition to the constraints also cross-references are provided to DCAT. To save space, the following abbreviations are used to indicate in short the difference with DCAT:

A: reused as-is defined and expressed in DCAT-AP, or if it has been reused as-is from DCAT in case the property was not explicitly mentioned in DCAT-AP
E: reused with additional usage notes or additional restrictions compared to DCAT-AP (or DCAT)
P: GeoDCAT-AP profile specific extension where DCAT-AP had no requirements earlier on specified

This reuse qualification assessement is w.r.t. a specific version of DCAT. Therefore it may vary over time when new versions of DCAT-AP are created.

INSPIRE and ISO 19115 Mappings

Objectives

The objective of this work is to define an RDF syntax that can be used for the exchange of descriptions of spatial datasets, dataset series, and services among data portals. The RDF syntax should extend the DCAT Application Profile for data portals in Europe [[DCAT-AP-3]].

To provide an RDF syntax binding for the union of the elements in the INSPIRE metadata schema [[INSPIRE-MD-REG]], [[INSPIRE-MD]] and the core profile of ISO 19115:2003 [[ISO-19115]]. The guiding design principle is to make the resulting RDF syntax as simple as possible; thereby maximally using existing RDF vocabularies – such as the Dublin Core [[DCTERMS]] and [[DCAT-AP-3]] –, and as much as possible avoiding minting new terms. The defined syntax binding must enable the conversion of metadata records from ISO 19115 / INSPIRE to a harmonised RDF representation. The ability to convert metadata records from RDF to ISO 19115 / INSPIRE is not a requirement.
To update the reference XSLT implementation [[GeoDCAT-XSLT]] of the mappings defined in the GeoDCAT-AP specification.
To take into account and refer to alignment of relevant controlled vocabularies (e.g., the alignments between GEMET, INSPIRE themes, EuroVoc carried out by the Publications Office of the EU [[EUV-EUROVOC]]).

Additionally, the following outcomes may be achieved, outside the context of this specification:

To define new controlled vocabularies or define mappings between controlled vocabularies.
To define an RDF syntax binding for the elements in ISO 19115-1:2014 [[?ISO-19115-1]].

Motivation and use cases

The basic use case that GeoDCAT-AP intends to enable is a cross-domain data portal search for datasets, as documented in the DCAT-AP specification [[DCAT-AP-3]]. GeoDCAT-AP will make it easier to share descriptions of spatial datasets between spatial data portals and general data portals, and thus help increase public and cross-sector access to such high value datasets. The datasets could include:

Datasets on the INSPIRE Geoportal: The INSPIRE Geoportal aggregates metadata for over 100k datasets across Europe. It provides the means to search for spatial data sets and spatial data services, and subject to access restrictions, to view spatial data sets from the EU Member States within the framework of the INSPIRE Directive. The metadata stored on this portal is structured according to the INSPIRE Metadata Technical Guidelines [[INSPIRE-MD]]. In order to maximise visibility and re-use, spatial datasets could also be listed on general-purpose Open Data Portals, such as data.europa.eu, the official portal for European data.
Datasets on national SDIs: GeoDCAT-AP would facilitate the integration of SDIs operated by EU Member States with any data catalogue able to consume [[DCAT-AP-3]]-compliant metadata.
General geospatial datasets: The geospatial community shares a common background and makes consistent use of consolidated standards and technologies. In particular, as far as metadata are concerned, it is widespread to use standards like [[ISO-19115]] / [[ISO-19139]], for the representation and encoding of metadata, and OGC’s [[?CSW]] (Catalog Service for the Web) for accessing and querying metadata records. These standards are also those required in INSPIRE.

An additional RDF syntax for INSPIRE and ISO 19115 metadata elements is beneficial, especially when other data portals support the [[DCAT-AP-3]] metadata elements only.

Conversion rules to RDF syntax would allow Member States to maintain their collections of INSPIRE-relevant datasets following the INSPIRE Metadata Technical Guidelines [[INSPIRE-MD]], while at the same time publishing these collections on [[DCAT-AP-3]]-conformant data portals. A conversion to RDF syntax – using for example the GeoDCAT-AP XSLT script [[GeoDCAT-XSLT]] - allows additional metadata elements to be displayed on general-purposed data portals, provided that such data portals are capable of displaying additional metadata elements. Furthermore, data portals are frequently complemented by a triple store, making the full set of GeoDCAT-AP metadata queryable through a SPARQL endpoint [[SPARQL11-QUERY]].

Supported tooling

To support the transformation from INSPIRE metadata to GeoDCAT-AP compliant metadata, a reference XSLT transformation was developed, and is being maintained. This transformation has been updated to transform data to be compliant with GeoDCAT-AP 3.0.0. The reference XSLT can be found in a GitHub repository. The XSLT can be run directly on the output of a CSW or on single metadata records, by using any of the programming languages supporting XSLT conversion.

The reference XSLT is not meant to be used in production directly. It serves as a reference which needs to be adjusted according to the specific needs and practice of the individual metadata publishers, as the practice is currently not coherent across publishers in certain aspects. These aspects include:

Identifiers of datasets, dataset series, distributions and data services, and their persistence for HVD. A method for establishing the identifiers needs to be implemented.
Licenses for HVD in cases where they are identified by IRIs, but do not use the EU Vocabularies Licence NAL directly. See [[DCAT-AP-HVD]]. A mapping needs to be implemented.
Representation of Data Services and their connection to Datasets due to the INSPIRE metadata simplification. Identification of Data Services and a method for their connection to Datasets needs to be implemented.
Mapping of INSPIRE themes to EU Vocabularies Data themes for cases where the Data themes are not included in the source metadata.

Methodology and summary of results

Methodologically, the development of GeoDCAT-AP implies three main interrelated tasks:

Definition of alignment criteria and requirements.
Identification of the metadata elements to be covered by GeoDCAT-AP.
Definition of alignments for the metadata elements to be covered by GeoDCAT-AP.

These tasks and their results are described in the following sections.

Alignment criteria and requirements

The overall objectives of GeoDCAT-AP are:

Provide a [[DCAT-AP-3]]-conformant representation of geospatial metadata.
Provide an as much as possible comprehensive RDF-based representation of geospatial metadata, based on widely used vocabularies, trying, at the same time, to avoid semantic loss and to promote cross-domain re-use.
Ensure backward compatibiliy with previous versions of GeoDCAT-AP.

The first two goals, having a different scope and applying to different use cases (see ), are reflected in the two mapping profiles of GeoDCAT-AP, core and extended, described in .

Note that point (1) implies that:

GeoDCAT-AP must include, at least, all the mandatory [[DCAT-AP-3]] elements.
Vocabularies different from [[DCAT-AP-3]] can be used only for those geospatial metadata elements not supported in [[DCAT-AP-3]].

Another key criterion was to base as much as possible the defined alignments on existing practices, in particular those contributed by the GeoDCAT-AP WG. The objective was to build upon experiences having already addressed issues in scope of GeoDCAT-AP, and to avoid a negative impact on existing implementations.

Finally, as already mentioned in , whenever no suitable candidates were available in existing vocabularies to represent geospatial metadata elements, the possibility of defining new terms was not excluded. However, this option needed to be carefully assessed, and discarded whenever it might have led to a specification that was conflicting with standards under preparation.

As it will be explained in , no new terms have been defined in the current version of GeoDCAT-AP.

Metadata elements to be covered by GeoDCAT-AP

The general criterion used for this task was that GeoDCAT-AP would ideally cover all the metadata elements of the core of [[ISO-19115]] and those defined in INSPIRE, with the requirement that only optional elements MAY be excluded.

Based on this, the current version of GeoDCAT-AP covers the following set of metadata elements:

All the metadata elements in the core of [[ISO-19115]].
All the metadata elements defined in INSPIRE, with the exclusion of those not common to all the INSPIRE spatial data themes.

More precisely, the supported INSPIRE metadata elements include:

The set of metadata elements defined in the INSPIRE Metadata Regulation [[?INSPIRE-MD-REG]].
The set of metadata elements defined in the INSPIRE Data and Services Regulation (Article 13: “Metadata required for Interoperability”) [[INSPIRE-SDSS-REG]]. These elements are also listed in Appendix C.3 to the INSPIRE Metadata Technical Guidelines (version 2.2.0) [[INSPIRE-MD]].
The set of metadata elements recommended as common to most of the INSPIRE spatial data themes in the INSPIRE Data Specifications Technical Guidelines, and listed in the first table included in Appendix C.7 to the INSPIRE Metadata Technical Guidelines (version 2.2.0) [[INSPIRE-MD]]. These elements are the following ones:
- Maintenance information.
- Conceptual and domain consistency (Data quality – Logical consistency).

The full list of metadata elements covered by the current version of GeoDCAT-AP is available in to this document.

The metadata elements not supported in the current version of GeoDCAT-AP are those recommended only for specific INSPIRE spatial data themes in the INSPIRE Data Specifications Technical Guidelines, and listed in Appendix C.7 to the INSPIRE Metadata Technical Guidelines (version 2.2.0) [[INSPIRE-MD]].

These elements have been excluded in the current version of GeoDCAT-AP for the following reasons:

The priority was to support all those elements relevant to any dataset.
These elements are all optional.

Support to these metadata elements might be provided in future versions of GeoDCAT-AP.

Alignments defined in GeoDCAT-AP

The alignments defined in the current version of GeoDCAT-AP are the result of an iterative revision process of [[GeoDCAT-AP-20201223]], following the criteria illustrated in the previous sections and the review of the GeoDCAT-AP WG. Alignments for [[ISO-19115-1]] have not been defined. contains an overview of the most important changes with respect to [[ISO-19115]].

The work started with the review of [[DCAT-AP-3]], [[VOCAB-DCAT-3]], and [[INSPIRE-MD]], with the purpose of identifying possible disalignments of the mappings defined in [[GeoDCAT-AP]], as well as possible gaps in [[DCAT-AP-3]] and [[VOCAB-DCAT-3]], which may require the use of different vocabularies or the definition of new classes and/or properties in the GeoDCAT-AP namespace. In all these cases, backward compatibility with [[GeoDCAT-AP-20201223]] has been taken into account when implementing revisions.

Finally, the GeoDCAT-AP WG has worked in close coordination with the DCAT-AP WG, in order to ensure mutual compliance of the proposed solutions.

The results of this work, reflected in the current version of GeoDCAT-AP, can be summarised as follows:

Compliance with [[DCAT-AP-3]] is ensured: The geospatial metadata elements covered by the defined mappings include all those that in [[DCAT-AP-3]] are mandatory, plus a subset of those that are recommended and optional.
GeoDCAT-AP offers alignments for all the metadata elements illustrated in , by using existing vocabularies, and without defining new terms.

The majority of the alignments defined in GeoDCAT-AP provide a complete representation of the corresponding geospatial metadata elements, but some metadata elements have open issues:

Partial mappings: For some metadata elements, only a partial mapping is available. This concerns data quality and maintenance information, for which only the mandatory components have been mapped (for more details, see and , respectively). This decision was taken because existing vocabularies did not offer the ability to represent all the components of these metadata elements.

The details of the alignments defined in GeoDCAT-AP are illustrated in the following section.

RDF syntax bindings for INSPIRE and ISO 19115 metadata elements

The following sections provide the list of the bindings defined in GeoDCAT-AP for the RDF representation of INSPIRE metadata and the core of [[ISO-19115]].

For detailed usage notes and examples of each of the metadata elements covered by GeoDCAT-AP, we refer the reader to (the relevant section is specified in the “comments” column of the mapping table).

There are three basic situations for each binding defined below:

Binding directly supported by [[DCAT-AP-3]]: binding is defined as part of GeoDCAT-AP Core
Binding partially supported by [[DCAT-AP-3]]: binding is defined as part of GeoDCAT-AP Core and supplemented by a binding in GeoDCAT-AP Extended
Binding not supported by [[DCAT-AP-3]]: binding is defined as part of GeoDCAT-AP Extended

Overview of bindings for GeoDCAT-AP Core

This section provides an overview of GeoDCAT-AP Core. This includes bindings for metadata elements of the INSPIRE metadata, metadata elements in the core of [[ISO-19115]] for which DCAT-AP provides an RDF syntax binding, and metadata elements supporting common practice, such as . Those metadata elements for which [[DCAT-AP-3]] does not provide a binding are part of the GeoDCAT-AP Extended mapping profile described in .

GeoDCAT-AP Core is meant to enable the harvesting and re-use of spatial metadata records through [[DCAT-AP-3]]-conformant applications and services, including data portals and APIs. The alignments for INSPIRE and [[ISO-19115]] metadata elements that are not included in GeoDCAT-AP Core are defined in GeoDCAT-AP Extended, see .

In the following table, the starred elements (*) are used to indicate the corresponding metadata element in the core of [[ISO-19115]]. For each element, it is indicated whether the element is mandatory (M), optional (O), conditional (C), or recommended (R) in either specification.

Overview of bindings for GeoDCAT-AP Extended

This section provides an overview of the RDF syntax bindings in GeoDCAT-AP Extended. This GeoDCAT-AP mapping profile covers elements defined in INSPIRE and the core of [[ISO-19115]], for which [[DCAT-AP-3]] does not provide a fully suitable syntax binding. GeoDCAT-AP Extended therefore complements GeoDCAT-AP Core with a more complete representation beyond [[DCAT-AP-3]].

The following table contains the defined RDF syntax binding for INSPIRE metadata. In the table below, the starred elements (*) are used to indicate the corresponding metadata element in the core of [[ISO-19115]]. For each metadata element, it is indicated whether the element is mandatory (M), optional (O), conditional (C), or recommended (R) in either specification.

Please note that some metadata elements have an RDF syntax binding in both the GeoDCAT-AP Core and Extended mapping profile. These elements fall in one of the following two categories:

Partial coverage by a [[DCAT-AP-3]] binding: This concerns conformity (only degree of conformity equal to “conformant” is supported) and responsible organisation (only responsible party roles creator, publisher, and point of contact are supported).
Subsumption by a GeoDCAT-AP RDF binding: ISO metadata elements available in GeoDCAT-AP Core, but for which only a many-to-one mapping is supported in [[DCAT-AP-3]].

In order to preserve the original semantics, the extended mapping profile of GeoDCAT-AP defines additional alignments to those included in GeoDCAT-AP Core. The two sets of alignments are not mutually exclusive, and can coexist without creating conflicts.

Resource title - *Dataset title

The content of the element ‘resource title’ can be represented in RDF as a plain literal, and by using property dct:title.

This binding may also include the specification of the language by using attribute @xml:lang [[XML]]. The language to be specified is the one indicated by element metadata language, mapped to the language identifiers defined by IETF BCP 47 [[BCP47]].

Resource metadata in GeoDCAT-AP:

Resource type - *not in ISO 19115 core

[[VOCAB-DCAT-3]] and [[DCAT-AP-3]] provide specific classes that can be used to represent the INSPIRE notions of dataset, dataset series, and service, namely, dcat:Dataset, dcat:DatasetSeries, and dcat:DataService.

In order to explicitly indicate the correspondence with the relevant INSPIRE resource types, following the work on aligning INSPIRE Metadata and Dublin Core [[?INSPIRE-DC]], in the extended mapping profile of GeoDCAT-AP they will be denoted by using the resource type code list operated by the INSPIRE Registry [[INSPIRE-RT]], and by using geodcatap:resourceType. More precisely, the following URIs SHOULD be used to denote, respectively, dataset, series, and services:

Additionally, the spatial data service type can be specified by using geodcatap:serviceType with the corresponding code lists operated by the INSPIRE Registry [[INSPIRE-SDST]].

Resource locator - *On-line resource

In INSPIRE, this element, quoting, defines the link(s) to the resource and/or the link to additional information about the resource. [[VOCAB-DCAT-3]] has a property, namely, dcat:landingPage, having exactly the same purpose.

[[ISO-19115]] offers however the ability to specify the “type” of resource locator by using a specific code list (CI_OnlineFunctionCode), described in the following table:

ISO 19115 – CI_OnlineFunctionCode	Description
download	online instructions for transferring data from one storage device or system to another
information	online information about the resource
offlineAccess	online instructions for requesting the resource from the provider
order	online order process for obtaining the resource
search	online search interface for seeking out information about the resource

Based on this, the mappings of element “resource locator” for data sets and data set series will vary depending on the function code (when available), based on the following table.

ISO 19115 – CI_OnlineFunctionCode	Property	Domain	Range
(not provided)	`dcat:landingPage`	`dcat:Dataset`	`foaf:Document`
download	`dcat:accessURL`	`dcat:Distribution`	`rdfs:Resource`
Information	`foaf:page`	`dcat:Dataset`	`foaf:Document`
offlineAccess	`dcat:accessURL`	`dcat:Distribution`	`rdfs:Resource`
order	`dcat:accessURL`	`dcat:Distribution`	`rdfs:Resource`
search	`foaf:page`	`dcat:Dataset`	`foaf:Document`

However, whenever the URL points to a service endpoint, the resource locator SHOULD be always mapped to property dcat:accessURL, and complemented by additional two properties, namely, dcat:endpointURL and dcat:endpointDescription.

More precisely, if the URL is recognised as pointing to a capabilities document, the URL is mapped to property dcat:endpointDescription, whereas property dcat:endpointURL will take as value the URL without it query string component.

Properties dcat:endpointURL and dcat:endpointDescription will have as domain class dcat:DataService, linked to the dataset distribution via property dcat:accessService.

Finally, whenever it is possible to recognise the service protocol, this information will be specified by property geodcatap:serviceProtocol, taking as value the URI of the relevant specification from the INSPIRE Registry's code list for protocol values [[INSPIRE-PV]].

As far as services are concerned, the resource locator SHOULD be mapped to properties dcat:endpointURL, dcat:endpointDescription, and dct:conformsTo, as described above.

Unique resource identifier - *not in ISO 19115 core

In INSPIRE, this element is meant to uniquely identify a resource (dataset, series or service), and it is mandatory for datasets and series. It is specified by (a) a mandatory character string code and by (b) an optional character string namespace.

Based on [[DCAT-AP-3]], unique resource identifiers are mapped to dct:identifier (see ). The actual value is obtained by the concatenation of the values of the namespace (if specified) and of the code in the original metadata record.

Resource metadata in GeoDCAT-AP:

[] dct:identifier "1234567890"^^xsd:string .

Coupled resource - *not in ISO 19115 core

This element is used to link a service to the target datasets or dataset series.

Following [[VOCAB-DCAT-3]] and [DCAT-AP-3], this relationship is specified by using property dcat:servesDataset.

The target dataset or series SHOULD be preferably referred to by using its unique resource identifier, as in .

Resource language and metadata language - *Dataset language and Metadata language

In INSPIRE metadata, metadata and resource languages (which may be different) are specified by using the three-letter language codes defined in [[?ISO-639-2]].

Based on [[DCAT-AP-3]], both elements are specified with property dct:language, with the URI of the relevant language available from the relevant register operated by the EU Publications Office [[EUV-LANG]].

assumes that the metadata language is Dutch, and the resource language is German.

    ...
    </gmd:MD_DataIdentification>
  </gmd:identificationInfo>
  ...
</gmd:MD_Metadata>

The metadata language can be also used to specify the language of textual elements of resource metadata by using the @xml:lang attribute [[XML]].

Since @xml:lang takes as value language identifiers defined by IETF BCP 47 [[BCP47]], a mapping from the actual value of the metadata language is needed.

Topic category, originating controlled vocabulary, and keyword value - *Dataset topic category

In INSPIRE, these two elements have specific purposes. Quoting from the INSPIRE Metadata Regulation [[?INSPIRE-MD-REG]] (§2.1 and §3.1, respectively):

The topic category is a high-level classification scheme to assist in the grouping and topic-based search of available spatial data resources.
The keyword value is a commonly used word, formalised word or phrase used to describe the subject. While the topic category is too coarse for detailed queries, keywords help narrowing a full text search and they allow for structured keyword search.

Moreover, two types of keywords are allowed:

free keywords;
keywords taken from a controlled vocabulary.

Finally, topic categories apply only to datasets and dataset series.

Topic category and keyword in datasets and dataset series

As far as dataset metadata are concerned, in both [[VOCAB-DCAT-3]] and [[DCAT-AP-3]], a distinction is made only between free keywords and keywords from controlled vocabularies, associated with a URI. For the former, dcat:keyword is used, whereas for the latter dcat:theme (which is a sub-property of dct:subject). Since the INSPIRE Registry operates URI registers for topic categories and INSPIRE spatial data themes, and in order to keep the distinction existing in INSPIRE between topic categories and keywords, the mapping is as follows:

Topic category is mapped to geodcatap:topicCategory, and expressed by the corresponding URIs minted for the ISO code list in the INSPIRE Registry – reference register http://inspire.ec.europa.eu/metadata-codelist/TopicCategory;
Keywords not associated with a controlled vocabulary will be mapped to dcat:keyword;
INSPIRE spatial data themes are mapped to dcat:theme and expressed by the corresponding URI in the INSPIRE Registry – reference register http://inspire.ec.europa.eu/theme;
Keywords associated with other controlled vocabularies are mapped to dcat:theme.

Following [[DCAT-AP-3]] recommendations, keywords from controlled vocabularies SHOULD be preferably specified with dereferenceable HTTP URIs. In such a case, the information concerning the originating controlled vocabulary can be omitted.

When keywords cannot be specified with HTTP URIs, they SHOULD be typed as a skos:Concept associated with a skos:ConceptScheme (used to type the originating controlled vocabulary), and annotated with the textual content and reference date(s) in the relevant INSPIRE metadata elements.

The representation of the information concerning the controlled vocabulary is illustrated in the following table.

Metadata Element			Proposed mapping
Originating controlled vocabulary	Title		`skos:ConceptScheme`	`dct:title`
	Reference date	creation		`dct:created`
		last revision		`dct:modified`
		publication		`dct:issued`

For conformance with [[DCAT-AP-3]], GeoDCAT-AP records MUST also include keywords from the EU Vocabularies Data Theme Named Authority List [[EUV-THEMES]].

In order to ensure consistency, the relevant EU Vocabularies Data Theme keywords SHOULD be selected based on mappings with the controlled vocabularies used in INSPIRE / ISO 19115 metadata.

Keyword in services

As far as service metadata are concerned, keywords can classify either a service or the datasets / series operated by the service itself. For the latter, INSPIRE Metadata Regulation requires using at least one of the keywords from the ISO 19119 code list of spatial data service categories.

In order to keep the distinction between these two types of keywords, the adopted solution is as follows:

Keywords from the ISO 19119 codelist of spatial data service types mapped to geodcatap:serviceType, and expressed by the corresponding URI in the INSPIRE Registry – reference register http://inspire.ec.europa.eu/metadata-codelist/SpatialDataServiceType;
Keywords from the ISO 19119 codelist of spatial data service categories are mapped to geodcatap:serviceCategory, and expressed by the corresponding URI in the INSPIRE Registry – reference register http://inspire.ec.europa.eu/metadata-codelist/SpatialDataServiceCategory;
Keywords not associated with a controlled vocabulary will be mapped to dcat:keyword, and represented as un-typed literals;
INSPIRE spatial data themes are mapped to dcat:theme, and expressed by the corresponding URI in the INSPIRE Registry – reference register http://inspire.ec.europa.eu/theme
Keywords associated with other controlled vocabularies are mapped to dcat:theme. If not denoted by an HTTP URI, they SHOULD be expressed as a skos:Concept associated with a skos:ConceptScheme, and annotated with the textual content and reference date(s) in the relevant INSPIRE metadata elements.

Spatial data service type - *not in ISO 19115 core

See on resource type.

Geographic bounding box - *Geographic location of the dataset (by 4 coordinates or by geographic identifier)

In the core of [[ISO-19115]], spatial coverage can be specified either with a bounding box (a geometry) or a geographic identifier. INSPIRE is more restrictive, in that it requires using a bounding box

Based on that, GeoDCAT-AP specified spatial coverage as illustrated in the following sections.

Bounding box

As a general rule, when the area corresponding to the spatial coverage is denoted by a geometry, as in INSPIRE, [[DCAT-AP-3]] recommends the use of the Core Location Vocabulary [[LOCN]], where this is done by using property locn:geometry, having as range a geometry specified as

a URI - e.g., by using the geo URI scheme (IET RFC-5870) [[?RFC5870]], or a geohash URI [[?GEOHASH]], [[?GEOHASH-36]];
a syntax encoding scheme - e.g., geohashes [[?GEOHASH]], [[?GEOHASH-36]], WKT [[?ISO-19125-1]], GML [[?GML]], KML [[?KML]], GeoJSON [[?RFC7946]]; or
a semantic representation - using vocabularies like W3C Lat/long [[?W3C-BASIC-GEO]] or schema.org [[?SCHEMA-ORG]].

However, in case the geometry is a bounding box or a centroid, properties dcat:bbox and dcat:centroid, respectively, SHOULD be used instead of locn:geometry.

It is worth noting that currently there is no agreement on a preferred format to be used in RDF for the representation of geometries. In GeoDCAT-AP, geometries can be provided in any, and possibly multiple, encodings, but at least one of the following must be made available: WKT or GML. An additional requirement concerns the coordinate reference system (CRS) used, which may vary on a country or territory basis. The CRS must be specified in the GML or WKT encoding as required by GeoSPARQL [[GeoSPARQL11]]. Geometries shall be interpreted using the axis order defined in the spatial reference system used. For example, for CRS84 the axis order is longitude / latitude, whereas for WGS84 the axis order is latitude / longitude. Summarising:

Geometries MAY be provided in multiple encodings, but at least one of the following MUST be made available: GML and WKT.
For GML and WKT, the CRS MUST be specified as defined in GeoSPARQL [[GeoSPARQL11]].

As geometries may be provided in multiple encodings, the corresponding datatype SHOULD be always specified to ensure that the geometry literal is correctly interpreted.

For GML and WKT, the [[GeoSPARQL11]] datatypes gsp:gmlLiteral and gsp:wktLiteral, respectively, MUST be used.

For GeoJSON [[?RFC7946]], datatype gsp:geoJSONLiteral, defined in GeoSPARQL, version 1.1 [[?GeoSPARQL11]], SHOULD be used.

For the other geometry encodings, no datatype is currently available. Therefore, their interoperability is not ensured when metadata records are shared or harvested across catalogues.

Resource metadata in GeoDCAT-AP using a geographic bounding box. This example uses multiple encodings, namely, the recommended ones (GML and WKT), plus GeoJSON.

Geographic identifier

[[ISO-19115]] core also allows specifying the geographic location using a geographic identifier. Following [[DCAT-AP-3]], for this, it is RECOMMENDED to use an HTTP URI from one of the following registers / gazetteers:

The Named Authority Lists operated by the Metadata Registry of the EU Publications office concerning continents [[EUV-CONT]], countries [[EUV-COUNTRIES]], and places [[EUV-PLACES]].

If none of the above provides the relevant geographic identifiers, Geonames [[?GEONAMES]] SHOULD be used.

If an HTTP URI is not available, the geographic identifier MUST be expressed with skos:prefLabel, and the reference to the originating controlled vocabulary (if any) MUST be specified with skos:inScheme. The controlled vocabulary will be described by a name (dct:title) and a last modified data (dct:modified).

As far as geographic identifiers are concerned, following [[DCAT-AP-3]], GeoDCAT-AP does not prevent the use other vocabularies in addition to the recommended ones. The vocabularies identified by the GeoDCAT-AP WG are listed in .

Temporal reference and metadata date –Additional extent information for the dataset (vertical and temporal) and Metadata date stamp

Temporal reference is a composite element consisting of the following possible child elements:

temporal extent (temporal coverage);
date of publication, last revision, and/or creation.

Based on [[DCAT-AP-3]], temporal extent is mapped to dct:temporal, having as range dct:PeriodOfTime. The time instant or interval is specified by using properties dcat:startDate and dcat:endDate, respectively.

By contrast, date of publication, last revision, and creation are mapped, respectively, to dct:issued, dct:modified (both core and extended GeoDCAT-AP mapping profiles), and dct:created (only for the extended mapping profile of GeoDCAT-AP).

[[DCAT-AP-3]] does not have a property equivalent to the INSPIRE metadata element metadata date. In INSPIRE, this element is defined as follows (see [[INSPIRE-MD-REG]], Part B, §10.2):

The date which specifies when the metadata record was created or updated.

Due to this ambiguity, the defined mapping for this element is dct:modified.

Spatial resolution – Spatial resolution of the dataset

[[VOCAB-DCAT-3]] and [[DCAT-AP-3]] provide property dcat:spatialResolutionInMeters, to specify spatial resolution as distance in metres. Morever, [[VOCAB-DCAT-3]] and [[?SDW-BP]] recommend the use of [[VOCAB-DQV]] to specify other types of spatial resolution, via property dqv:hasQualityMeasurement.

Based on this, GeoDCAT-AP specifies spatial resolution as follows:

Property dcat:spatialResolutionInMeters is used for spatial resolution when it is expressed as distance in metres.
Property dqv:hasQualityMeasurement is used for all types of spatial resolution. In such a case, the type of spatial resolution is specified by using property dqv:isMeasurementOf, which takes as value the relevant instance of class dqv:Metric defined in GeoDCAT-AP for this purpose (see Instances of Metric).
Property geodcatap:spatialResolutionAsText is used when spatial resolution is specified as free-text.

The core mapping profile of GeoDCAT-AP, following [[DCAT-AP-3]], supports only the use property dcat:spatialResolutionInMeters, and, therefore, the other types of spatial resolution are left unmapped.

Conformity and data quality - *not in ISO 19115 core

In [[ISO-19115]], conformance and quality information is encoded as a quality report containing the result of a test (an evaluation) of a given quality measure, according to an evaluation method, with either a quantitative result (a metric) or a conformance result (pass or fail) as most important outcome.

The current version of GeoDCAT-AP only defines a syntax binding for conformity and not for data quality in general, making use of property dct:conformsTo and the W3C Provenance Ontology (PROV-O) [[PROV-O]], as explained in the following paragraphs.

[[DCAT-AP-3]] provides a single candidate, dct:conformsTo, which however can be used to map only a conformity of degree ‘conformant’. This is suitable for the core mapping profile of GeoDCAT-AP.

Considering how conformity must be expressed in extended mapping profile of GeoDCAT-AP (see [[INSPIRE-MD-REG]], Part B, §7), possible candidates are the W3C Evaluation and Report Language (EARL) [[?EARL10]] and the W3C Provenance Ontology (PROV-O) [[PROV-O]]. The latter candidate was chosen by the GeoDCAT-AP Working Group, since it would enable wider re-use with respect to the EARL vocabulary, which is more specific, and its use is limited.

[[PROV-O]] allows encoding conformity as a test activity (prov:Activity) that generated a result specified with property prov:generated, corresponding to the degree of conformity, for which the INSPIRE Registry maintains a URI set [[INSPIRE-DoC]]. The specification against which the conformance is asserted is specified via a qualified association (prov:qualifiedAssociation) with a test plan (a prov:Plan) in turn derived from a standard (dct:Standard, also prov:Entity). These associations are made via a property chain: prov:qualifiedAssociation, prov:hadPlan, and prov:wasDerivedFrom.

This pattern is illustrated in the following table.

Metadata element				Proposed mapping
Conformity	Specification (M)	Title		`prov:wasUsedBy` (range `prov:Activity`)	`prov:qualifiedAssociation` (range `prov:Assocation`) > `prov:hadPlan` (range `prov:Plan`) > `prov:wasDerivedFrom` (range: `prov:Entity`, `dct:Standard`)	`dct:title`
		Reference date	creation			`dct:created`
			last revision			`dct:modified`
			publication			`dct:issued`
	Degree (M)				`prov:generated` (range `prov:Entity`)	`dct:type` (range [[INSPIRE-DoC]])
	Degree (M)				`prov:generated` (range `prov:Entity`)	`dct:description`

In order to grant interoperability with [[DCAT-AP-3]], when conformity is of degree “conformant”, the proposal is to use both [[PROV-O]] and dct:conformsTo for GeoDCAT-AP Extended.

Conditions for access and use and limitations on public access – Use limitation and access / other constraints

In [[DCAT-AP-3]], licensing information is specified on (a) data catalogues (services) and on (b) the distribution(s) of a dataset, and not on the dataset itself. The principle is that different dataset distributions may be associated with different licensing terms. Moreover, [[DCAT-AP-3]] recommends the use of dct:accessRights for specifying access conditions. Both licenses and access rights should be indicated by their corresponding URIs.

Based on this, GeoDCAT-AP specifies use and access limitations by using, respectively, dct:license and dct:accessRights whenever the value is available as a URI. Otherwise, since the range of these properties is not a literal, but, respectively, classes dct:LicenseDocument and dct:RightsStatement, the free-text content of the corresponding ISO 19115 / INSPIRE metadata elements can be expressed using dct:description on the dct:RightsStatement instance, connected using the dct:rights property.

Responsible party and metadata point of contact - Dataset responsible party and Metadata point of contact

[[DCAT-AP-3]] supports properties to denote the publisher, the creator, and the contact point for a dataset.

By contrast, [[ISO-19115]] and [[INSPIRE-MD-REG]] support 11 possible relationships between a resource (a dataset, a dataset series, a service) and an agent (organisation), plus one for metadata. However, for only some of them suitable candidates exist from widely used vocabularies (in particular, DCMI Metadata Terms [[DCTERMS]]).

In order to fill this gap, specific properties have been defined in the GeoDCAT-AP namespace to complement those available in [[DCAT-AP-3]] and [[DCTERMS]].

The following table lists the mappings between responsible party roles and the corresponding properties used in GeoDCAT-AP.

[[ISO-19115]]	[[INSPIRE-MD-REG]]	Description	Proposed RDF mapping
Resource provider	Part B, §6.1	Party that supplies the resource.	`geodcatap:resourceProvider`
Custodian	Part B, §6.2	Party that accepts accountability and responsibility for the data and ensures appropriate care and maintenance of the resource.	`geodcatap:custodian`
Owner	Part B, §6.3	Party that owns the resource.	`dct:rightsHolder`
User	Part B, §6.4	Party who uses the resource.	`geodcatap:user`
Distributor	Part B, §6.5	Party who distributes the resource	`geodcatap:distributor`
Originator	Part B, §6.6	Party who created the resource.	`geodcatap:originator`
Point of contact	Part B, §6.7	Party who can be contacted for acquiring knowledge about or acquisition of the resource.	`dcat:contactPoint`
Principal investigator	Part B, §6.8	Key party responsible for gathering information and conducting research	`geodcatap:principalInvestigator`
Processor	Part B, §6.9	Party who has processed the data in a manner such that the resource has been modified.	`geodcatap:processor`
Publisher	Part B, §6.10	Party who published the resource	`dct:publisher`
Author	Part B, §6.11	Party who authored the resource.	`dct:creator`

The extended mapping profile of GeoDCAT-AP also supports the use of the W3C PROV ontology [[PROV-O]] and [[VOCAB-DCAT-3]] to specify the relationship between the resource and the responsible organisation. The FOAF Vocabulary [[FOAF]] is used to specify the contact information concerning the responsible party. Finally, the responsible party role will be specified by using dcat:hadRole, and using the relevant code list values from the INSPIRE Registry – reference register [[INSPIRE-RPR]]:

http://inspire.ec.europa.eu/metadata-codelist/ResponsiblePartyRole

These mappings are illustrated in the following table.

Metadata element			Proposed mapping
Responsible party	Responsible party	Organisation name	`prov:qualifiedAttribution` (range `prov:Attribution`)	`prov:agent` (range `prov:Agent`, `foaf:Agent`)	`foaf:name`
	Responsible party	Contact email address		`prov:agent` (range `prov:Agent`, `foaf:Agent`)	`foaf:mbox`
	Responsible party role			`dcat:hadRole` (range `dcat:Role`)

It is important to note that the [[PROV-O]]-based mappings are semantically equivalent to the property-based ones illustrated earlier in this section. Their use is therefore only accessory, and functional to possible requirements from the data provider side.

For these reasons, the GeoDCAT-AP overall approach is as follows:

Responsible parties and their roles MUST be represented by the corresponding properties, based on an agreed definition of 1-to-1 mappings.
The property-based representation MAY be complemented with the [[PROV-O]]-based approach.

As mentioned earlier, the latter option is supported only in the extended mapping profile of GeoDCAT-AP.

In this example, the same organisation is both the data custodian and the metadata point of contact.

*Metadata file identifier

This element identifies a metadata record.

Metadata file identifiers are mapped to dct:identifier.

Metadata on metadata in GeoDCAT-AP:

[] a dcat:CatalogRecord ;
  dct:identifier "947e5a55-e548-11e1-9105-0017085a97ab"^^xsd:string .

    </gco:CharacterString>
  </gmd:fileIdentifier>
  ...
</gmd:MD_Metadata>

If the metadata file identifier is or can be encoded as an HTTP URI, it can also be used as the URI of the catalogue record (see ).

Metadata on metadata in GeoDCAT-AP:

Metadata standard name, Metadata standard version

Following [[DCAT-AP-3]], GeoDCAT-AP uses dct:conformsTo to specify the metadata standard, and properties dct:title and owl:versionInfo are used to specify the standard name and version, respectively.

This pattern is illustrated in the following table.

Metadata element		Proposed mapping
Metadata standard	Metadata standard name	`dct:conformsTo` (range `dct:Standard`)	`dct:title`
Metadata standard	Metadata standard version	`dct:conformsTo` (range `dct:Standard`)	`owl:versionInfo`

shows a GeoDCAT-AP metadata record obtained from one conformant with [[ISO-19115]].

Metadata on metadata in GeoDCAT-AP:

Coordinate reference systems and Temporal reference systems – *Reference System

In GeoDCAT-AP, these elements are mapped to property geodcatap:referenceSystem. Moreover, in order to indicate which type of a reference system the object of geodcatap:referenceSystem denotes, an additional statement with predicate dct:type is added, with a code list value defining the notion of (spatial / temporal) reference system, taken from the glossary operated by the INSPIRE Registry [[INSPIRE-GLOSSARY]].

More precisely, the following URIs SHOULD be used to denote, respectively, spatial and temporal reference systems:

The reference system identifier SHOULD be preferably represented with an HTTP URI. In particular, spatial reference systems should be specified by using the corresponding URIs from the “EPSG coordinate reference systems” register operated by the Open Geospatial Consortium [[OGC-EPSG]].

In this register, the URI prefix for coordinate reference systems is the following one:

http://www.opengis.net/def/crs/EPSG/0/

followed by the number identifying the coordinate reference system in the EPSG register. For instance, the following URI

http://www.opengis.net/def/crs/EPSG/0/4258

identifies coordinate reference system EPSG 4258, corresponding to ETRS89 (European Terrestrial Reference System 1989).

In case the reference system is not specified as an HTTP URI, the mapping covers also other information included in the source metadata - as the identifier (dct:identifier), name (dct:title), and version (owl:versionInfo), plus a reference to the relevant register, if available (skos:inScheme). If a reference register is available, the reference system is implicitly also a skos:Concept, and its name can be specified by using skos:prefLabel.

Resource metadata in GeoDCAT-AP:

  geodcatap:referenceSystem <http://www.opengis.net/def/crs/EPSG/0/4258> .

Character encoding - Dataset character set and Metadata character set

In [[VOCAB-DCAT-3]] and [[DCAT-AP-3]], the specification of the character encoding of a dataset and the character encoding of a metadata record is not explicitly supported. Moreover, since GeoDCAT-AP is an RDF-based specification, the metadata represented using GeoDCAT-AP are always in the UTF-8 encoding.

According to [[?RFC4288]], the character set can be part of the media type specification, but only for type “text”. By contrast, in INSPIRE the character set can be specified also for other media types.

The W3C Content vocabulary [[Content-in-RDF10]] provides a possibly suitable candidate, namely, property cnt:characterEncoding, taking as value the character set names in the IANA register [[IANA-CHARSETS]]. GeoDCAT-AP uses this property.

Character encoding in [[ISO-19115]] metadata is specified with a code list that can be mapped to the corresponding codes in [[IANA-CHARSETS]], as shown in the following table (entries with 1-to-many mappings are in italic).

Encoding - *Distribution format

In both [[VOCAB-DCAT-3]] and [[DCAT-AP-3]], this information is specified for the distribution(s) of a dataset, and not for the dataset itself.

Two properties are available:

dcat:mediaType: to be used when the format corresponds to one of the media types registered by IANA [[IANA-MEDIA-TYPES]].
dct:format: to be used in all the other cases, to be used with file type register operated by the Publications Office of the EU [[EUV-FT]].

The same approach is used in GeoDCAT-AP for ISO 19115 / INSPIRE metadata.

Spatial representation type – *Spatial representation type

In [[DCAT-AP-3]], no equivalent term is provided.

In [[ISO-19115]], element “Spatial representation type” is meant mainly to describe the “method used to represent geographic information in the dataset”, by using a code list (see the table below).

The ADMS vocabulary [[VOCAB-ADMS]] includes a property, namely, adms:representationTechnique that could be used for this purpose. It is worth noting that, in the ADMS specification, adms:representationTechnique decribes a distribution, and not the dataset. Moreover, the [[ISO-19115]] code list of spatial representation types is available as a URI register from the INSPIRE Registry [[INSPIRE-SRT]].

Based on this, GeoDCAT-AP specifies this information by using property adms:representationTechnique, with the spatial representation type URIs operated by the INSPIRE Registry [[INSPIRE-SRT]].

This mapping is supported only in the extended mapping profile of GeoDCAT-AP.

The spatial representation types defined in [[ISO-19115]] are listed in the following table. It is important to note that, as stated in the INSPIRE Data Specifications, the only spatial representation types in scope of INSPIRE are the following ones: “vector”, “grid”, and “tin”.

ISO 19115 - MD_SpatialRepresentionTypeCode	Description	In scope of INSPIRE?
vector	vector data is used to represent geographic data	Yes
grid	grid data is used to represent geographic data	Yes
textTable	textual or tabular data is used to represent geographic data	No
tin	triangulated irregular network	Yes
stereoModel	three-dimensional view formed by the intersecting homologous rays of an overlapping pair of images	No
video	scene from a video recording	No

Maintenance information - *not in ISO 19115 core

In [[ISO-19115]], element “Maintenance information” is meant mainly to describe how frequently a resource is updated.

In [[DCAT-AP-3]], the update frequency is expressed through dct:accrualPeriodicity, with the frequency codes defined in the the EU Vocabularies Frequency Named Authority List [[EUV-FREQ]], which can be partially mapped to the ones used in [[ISO-19115]], as shown in the following table.

ISO 19115 - MD_MaintenanceFrequencyCode	Dublin Core Collection Description Frequency Vocabulary [[?CLD-FREQ]]	EU Vocabularies Frequency Named Authority List [[EUV-FREQ]]
continual	continuous	UPDATE_CONT / CONT
daily	daily	DAILY
weekly	weekly	WEEKLY
fortnightly	biweekly	BIWEEKLY
monthly	monthly	MONTHLY
quarterly	quarterly	QUARTERLY

-	semimonthly	MONTHLY_2
-	threeTimesAMonth	MONTHLY_3
-	semiweekly	WEEKLY_2
-	threeTimesAWeek	WEEKLY_3
-	-	OTHER

The [[ISO-19115]] code list of maintenance frequency codes is available as a URI register from the INSPIRE Registry [[INSPIRE-MF]].

Based on this, maintenance frequency is specified in GeoDCAT-AP by using dct:accrualPeriodicity with the EU Vocabularies Frequency Named Authority List [[EUV-FREQ]].

For the frequency codes not covered by the EU Vocabularies Frequency code list, the approach will be as follows:

In the core mapping profile of GeoDCAT-AP these codes will be ignored.
The extended mapping profile of GeoDCAT-AP will use the code list of ISO maintenance frequency codes operated by the INSPIRE Registry [[INSPIRE-MF]].

Comparison between INSPIRE and ISO 19115-1:2014

In [[?ISO-19115-1]] the concept of ‘Core metadata’ was removed; it was translated into a normative annex (Annex F) “Discovery metadata for geographic resources”. In the Annex F metadata elements for the discovery are listed in 2 tables:

the metadata elements to be used for discovery of geographic datasets and series are identified in F.1;
the metadata elements to be used for discovery of service resources are identified in F.2.

Spatial dataset and spatial dataset series

The table below compares the core requirements of ISO 19115:2003 (see Table 3 in 6.5 of [[?ISO-19115]]), the requirements of INSPIRE for spatial dataset and spatial dataset series as defined in the Implementing Rules for metadata and the discovery metadata for geographic datasets and series (see Table F.1 in annex F of [[?ISO-19115-1]]). For those last metadata elements in the last field of the table the path is indicated. For each element, in brackets the obligation/max occurrence (3rd field).
