This document contains version 3.0.0 of the specification for GeoDCAT-AP, 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]], its XML metadata encoding standard, ISO/TS 19139:2007 [[ISO-19139]], and those defined in the framework of the INSPIRE Directive [[INSPIRE-DIR]].
The GeoDCAT-AP specification does not replace the INSPIRE Metadata Regulation [[?INSPIRE-MD-REG]] nor the INSPIRE Metadata technical guidelines [[INSPIRE-MD]] based on ISO 19115 and ISO 19119. Its purpose is to give producers and maintainers of geospatial metadata the possibility to achieve more by providing the means of an additional implementation through harmonised RDF syntax bindings used in the Open Data community. Conversion rules to RDF syntax would allow Member States to maintain their collections of INSPIRE-relevant datasets following the INSPIRE Metadata technical guidelines based on [[ISO-19115]] and [[ISO-19119]], while at the same time publishing these collections on [[DCAT-AP-3]]-conformant data portals. A conversion to an RDF representation allows additional metadata elements to be displayed on general-purposed open data portals, provided that such data portals are capable of displaying additional metadata elements. Additionally, data portals may be capable of providing machine-to-machine interfaces where additional metadata could be provided.
With a view to fostering Europe's digital transformation, the European Commission is investing in frameworks and agreements to provide governments and businesses with the appropriate resources to digitalise their services. There are, for instance, building blocks available for creating a single market for data, where data flows freely within the EU and across sectors for the benefit of businesses, researchers and public administrations.
To this direction, the European Commission launched the European Data Strategy [[DataStrategy]], as part of the European Commission's priorities for 2019-2024 in order to make the EU a leader in a data-driven society.
Studies previously conducted on behalf of the European Commission (e.g., [[Vickery]]) shed light on the importance of having data findable and available in machine readable format in order to stimulate its reuse. This vision led to several legislative actions to reduce barriers and promote data sharing, such as the Open Data Directive [[OPENDATA-DIR]], which turned out to be a driving force towards a more transparent and fair access to government data.
With this regard, the wide range of (open) data portals developed by European public administrations is the result of this mission. These Web-based interfaces allow access to data by providing users means to explore a catalogue of datasets. To facilitate the sharing, discovery and re-use of the data beyond the (open) data portal, common agreements for the exchange of catalogues of datasets are needed. These interoperability agreements enable to connect (open) data catalogues into a pan-european catalogue of datasets.
The DCAT Application Profile specifies the generic agreements for (open) data portals operated by public administrations in Europe. This specification extends DCAT-AP with additional requirements for describing geospatial data.
The current document is the result of the major semantic change release process described in the Change and Release Management Policy for DCAT-AP [[DCAT-AP-CRMP]] and was built starting from GeoDCAT-AP version 2.0.0 [[GeoDCAT-AP-20201223]], with the purpose of aligning it with DCAT-AP version 3.x.x [[DCAT-AP-3]] and with version 2.2.0 of the INSPIRE Metadata Technical Guidelines for the implementation of INSPIRE dataset and service metadata based on ISO/TS 19139:2007 [[INSPIRE-MD]].
This work has been carried out in the context of the European Commission’s Interoperable Europe
initiative [[INTEROPERABLE-EUROPE]].
The objective of this work is to produce an updated release of GeoDCAT-AP based on requests for change coming from real-world implementations of the specification and an alignment with [[DCAT-AP-3]] and [[INSPIRE-MD]].
As [[[DCAT-AP-3]]], the Application Profile specified in this document is based on the specification of the Data Catalog Vocabulary (DCAT). DCAT is originally developed under the responsibility of the Government Linked Data Working Group [[GLD]] at W3C, and was significantly revised in 2020 by the W3C Dataset Exchange Working Group [[DXWG]]. DCAT is an RDF [[RDF11-CONCEPTS]] vocabulary designed to facilitate interoperability between data catalogues published on the Web.
The objective of this work is to produce an extension of [[DCAT-AP-3]] based on numerous requests for change coming from real-world implementations of the specification listed on the GitHub issues section since the previous release [[GeoDCAT-AP-20201223]]. For that purpose the [[DCAT-AP-3]] specification is extended with improved definitions, usage notes and usage constraints such as cardinalities for properties and the usage of controlled vocabularies. Additional classes and properties are re-used or introduced where necessary.
The work does not cover implementation issues like mechanisms for exchange of data and expected behaviour of systems implementing the Application Profile other than what is defined in the Conformance Statement in section [[[#conformance]]].
The Application Profile is intended to facilitate data exchange and therefore the classes and properties defined in this document are only relevant for the data to be exchanged; there are no requirements for communicating systems to implement specific technical environments. The only requirement is that the systems can export and import data in RDF in conformance with this Application Profile.

The only requirement is that the systems can export and import data in RDF in conformance with this Application Profile.
As mentioned in the context, the prime objective of the Application Profile is to enhance data findability and promote reusability. To achieve this goal, datasets should be coherently documented. To enable this, the Application Profile considers several essential aspects, including among others:
Around 2010, on behalf of the European Commission the access to public sector information was studied. These studies showed that businesses and citizens faced many difficulties in finding and reusing public sector information. The studies indicated that the availability of the information in a machine-readable format as well as a thin layer of commonly agreed metadata could facilitate data cross-reference and interoperability and therefore considerably enhance its value for reuse. Therefore, to overcome these hurdles, the European Commission invested in policies [[PSI]], data interoperability [[SEMIC]] and infrastructure [[DEU]].
Interoperable Europe, within its mission to stimulate the data interoperability in Europe, manages this specification on the metadata agreements for sharing dataset descriptions between data portals. The governance is taken care by the SEMIC action within Interoperable Europe. Initially, the scope of the specification was the exchange between Open Data Portals in Europe. Although this is still at the core of the specification, DCAT-AP is not limited to publicly accessible Open Data, but can be applied to any kind of datasets. In the past decade, DCAT-AP has grown from a single specification to a whole ecosystem of related and interconnected specifications.
This application profile has the status Candidate Recommendation published at 2024-10-04.
Information about the process and the decisions involved in the creation of this specification are consultable at the Changelog.

An Application Profile is a specification that reuses terms from one or more base standards, adding more specificity by identifying mandatory, recommended and optional elements to be used for a particular application, as well as recommendations for controlled vocabularies to be used.
A Dataset is a collection of data, published or curated by a single source, and available for access or download in one or more formats. A Data Portal is a Web-based system that contains a data catalogue with descriptions of datasets and provides services enabling discovery and reuse of the datasets.

This Application Profile extends [[DCAT-AP-3]] by including
These extensions are meant to provide a DCAT-AP-conformant representation of geospatial metadata, identified by defining RDF syntax mappings covering the union of the elements in the INSPIRE metadata schema [[INSPIRE-MD-REG]], [[INSPIRE-MD]] and the core profile of [[ISO-19115]], following the criteria illustrated in A. INSPIRE and ISO 19115 Mappings.
The current specification does not change the set of geospatial metadata elements already covered in its previous version [[GeoDCAT-AP-20201223]], but rather it updates some of the corresponding mappings based on the new classes and properties included in [[DCAT-AP-3]], following the release of version 2 of the W3C Data Catalog (DCAT) Vocabulary [[vocab-dcat-3]], and aligns them with version 2.2.0 of the INSPIRE Metadata Technical Guidelines [[INSPIRE-MD]].
dcat:Resource
