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 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 datasets among data portals.
In February 2015, the ISA Programme of the European Commission has started an activity to revise the DCAT-AP, based on experience gained since its development in 2013.
Participate in the public review of the DCAT-AP
Dear Sir or Madam,
You are kindly invited to review the proposed revision of the DCAT Application Profile for data portals in Europe (DCAT-AP). The draft revision can be downloaded from https://joinup.ec.europa.eu/node/137964. It is available for public review until the 30th of August 2015.
Please submit your feedback by sending comments and suggestions to email@example.com. The feedback received will be discussed by the DCAT-AP Revision Working Group in late August and early September. Final publication of the revised Application Profile is foreseen for September 2015.
The DCAT-AP is a specification based on the Data Catalog Vocabulary (DCAT) of W3C, which is an RDF vocabulary designed to facilitate interoperability between data catalogues published on the Web. In the Application Profile, additional classes and properties from other well-known vocabularies have been re-used where necessary. The basic use case of the DCAT-AP is to enable aggregation of and search for datasets across data portals in Europe, thus making it easier to find public sector datasets across borders and sectors.
The DCAT-AP has been developed in the context of Action 1.1 – Improving semantic interoperability in European eGovernment systems of the European Commission’s Interoperability Solutions for European Public Administrations (ISA) programme. The DCAT-AP is a joint initiative of two Directorates-General of the European Commission: DG DIGIT (ISA Programme) and DG CONNECT, together with the Publications Office of the EU. The Publications Office chairs the DCAT-AP Revision Working Group.
Looking forward to receiving your feedback.
Participate in the extension of the GeoDCAT-AP
GeoDCAT-AP is an extension of DCAT-AP for describing geospatial datasets, data series, and services. The GeoDCAT-AP is currently under development by a Working Group. For more information on the GeoDCAT-AP initiative and the Wokring Group, please refer to the GeoDCAT-AP page.
The DCAT-AP is used in the Open Data Support service initiated by the European Commission with the purpose of realising the vision of European data portals. Moreover, the DCAT-AP is the standard that will be used for describing datasets on the Pan-European Data Portal, which is currently under development.
The Swedish innovation agency VINNOVA, which runs the Swedish Open Data Portal, in collaboration with Open Knowledge UK and MetaSolutions have undertaken many activities to support DCAT-AP in the Swedish Open Data Portal, including:

Studies conducted on behalf of the European Commission (see this link for an overview) show that businesses and citizens still face difficulties in finding and re-using public sector information. In its communication on Open Data of December 12 2011, the European Commission states 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.
The aim to ensure consistency in the description metadata published by data portals across Europe is important and has a clear business case. We see the following scenarios:
The application profile is a specification for metadata records to meet the specific application needs of data portals in Europe while providing semantic interoperability with other applications on the basis of reuse of established controlled vocabularies (e.g. EuroVoc) and mappings to existing metadata vocabularies (e.g. Dublin Core, SDMX, INSPIRE metadata, etc).
