Introduction

This document specifies the set of RDF classes and properties used in the DCAT Application profile for data portals in Europe (DCAT-AP).

The DCAT Application profile for data portals in Europe (DCAT-AP) is a specification based on the Data Catalogue vocabulary (DCAT) for describing public sector datasets in Europe. Its basic use case is to enable a cross-data portal search for data sets and make public sector data better searchable across borders and sectors. This can be achieved by the exchange of descriptions of data sets among data portals.

Full documentation is provided in the specification document itself. This includes background information, use cases, the UML class diagram, and full definitions for all terms used.

Namespace

This application profile is derived from the Data Catalog Vocabulary (DCAT), with main URI:

http://www.w3.org/ns/dcat#

When abbreviating terms the suggested prefix is dcat

Each class or property in the vocabulary has a URI constructed by appending a term name to the vocabulary URI. For example:

http://www.w3.org/ns/dcat#Catalog

UML Class Diagram

This section lists the classes, properties, and relationships contained in the application profile. The following sections indicate how these are represented in the RDF Schema.
