The final draft of the Data Catalogue Vocabulary Application Profile for data portals in Europe(DCAT-AP) is open for public review until 10 June 2013.
DCAT-AP is a specification based on 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.
You can find the draft and leave your comments (register and log-in) on the following page:https://joinup.ec.europa.eu/node/66194. All issues will be discussed by the DCAT Application Profile Working Group, in the Virtual Meeting which will take place on 12 June 2013.
