Introduction

Context

This vocabulary is supporting StatDCAT-AP, a specialisation of the DCAT application profile for European data portals [[DCAT-AP]] for statistical data. The terms defined in this namespace are defined as broad as possible for wider reuse but are scoped to the needs of StatDCAT-AP. All terms in this vocabulary have therefore a strong connection with StatDCAT-AP.

Revision history

This namespace document was created during the process of aligning the StatDCAT-AP profile with DCAT-AP 3.x and the SEMIC style guide in 2026.

Abstract

The StatDCAT-AP vocabulary supports the StatDCAT-AP profile. The namespace for this vocabulary is http://data.europa.eu/s1n/ . It is under maintenance by the SEMIC action, Interoperable Europe.

Status

This vocabulary has the status Working Draft published at 2026-05-14.

Information about the process and the decisions involved in the creation of this specification are consultable at the Changelog.

Conformance Statement

In order to conform to this vocabulary the usage of the terms MUST: When reusing the terms, the reuse principles of the SEMIC Style Guide SHOULD be followed.

To make the properties widely reuseable the domain and ranges are usually very open. For any kind of entity, the class rdfs:Resource is used. For any kind of value, rdfs:Literal is used. In the RDF ecosystem these are the universal denominators.

Terminology

The namespace for this vocabulary is http://data.europa.eu/s1n/ .

Vocabulary Overview

This specification describes the following classes:
| Dataflow |

and the following properties:
| attribute | data structure definition | dimension | measure | number of data series | unit of measurement |

Classes

This section lists the classes matching the base namespace of this vocabulary.

Dataflow

(create issue) Class Dataflow
URI http://data.europa.eu/s1n/Dataflow
label Dataflow
definition An abstract concept of the Data Sets, i.e. a structure without any data.
subclass of

Properties

This section lists the properties matching the base namespace of this vocabulary.

attribute

(create issue) Property attribute
URI http://data.europa.eu/s1n/attribute
label attribute
definition a component used to qualify and interpret observed values, e.g. units of measure, any scaling factors and metadata such as the status of the observation (e.g. estimated, provisional). Attribute is a "conceptual" entity that applies to all distribution formats, e.g. in case a dataset is provided both in SDMX and in DataCube.

data structure definition

(create issue) Property data structure definition
URI http://data.europa.eu/s1n/dataStructureDefinition
label data structure definition
definition Links a statistical dataset to the Data Structure Definition (DSD) that defines its dimensions, attributes, measures, and overall observation structure.

range

dimension

(create issue) Property dimension
URI http://data.europa.eu/s1n/dimension
label dimension
definition a component that identifies observations, e.g. the time to which the observation applies , or a geographic region which the observation covers. Dimension is a "conceptual" entity that applies to all distribution formats, e.g. in case a dataset is provided both in SDMX and in DataCube.

measure

(create issue) Property measure
URI http://data.europa.eu/s1n/measure
label measure
definition a component that represents the phenomenon being observed. Measure is a "conceptual" entity that applies to all distribution formats, e.g. in case a dataset is provided both in SDMX and in DataCube.
domain
http://www.w3.org/ns/dcat#Dataset
range
http://purl.org/linked-data/cube#MeasureProperty

number of data series

(create issue) Property number of data series
URI http://data.europa.eu/s1n/numSeries
label number of data series
definition represents the number of distinct time series available in the dataset that contain data. A distinct time series is defined as a unique combination of dimension values (such as country, sex, age, unit of measure, etc.) that has at least one observation value or attribute associated with it - where an attribute may include a flag even in the absence of an actual data value. Time (e.g., year) is treated as one dimension among others, not as a unit of aggregation.

unit of measurement

(create issue) Property unit of measurement
URI http://data.europa.eu/s1n/statUnitMeasure
label unit of measurement
definition a unit of measurement of the observations in the dataset, for example Euro, square kilometre, purchasing power standard (PPS), full-time equivalent, percentage. Unit of measurement is a "conceptual" entity that applies to all distribution formats, e.g. in the case when a dataset is provided both in SDMX and in Data Cube.
