(Not wearing my CG co-chair hat) Dear colleagues, Please find below the call for public review of GeoDCAT-AP, the extension to DCAT-AP ("DCAT application profile for data portals in Europe") developed in the framework of the EU ISA Programme to enable the cross-domain sharing and exchange of geospatial metadata [1]. GeoDCAT-AP does not define new terms, but uses existing cross-domain vocabularies (as Dublin Core, DCAT, PROV) to define a harmonised RDF representation of ISO 19115/19119 metadata. To achieve this, the WG had to deal with issues - like the representation of geometries, reference systems and spatial resolutions - that have been discussed quite a few times by the LOCADD CG. You may be interested in the solutions agreed upon by the GeoDCAT-AP WG (e.g., for geometries), also to deal with alignments still having open issues (e.g, reference systems and spatial resolution). As you will read in the call, GeoDCAT-AP is implemented in an XSLT [2] that can be run directly on CSW output or standalone ISO 19139 records to convert them into RDF. This tool comes together with a documentation, including a summary of the implemented mappings [3] and "where" in ISO 19139 records the XSLT expects to find HTTP URIs [4]. The plan is to carry out a number of pilot exercises with this XSLT, to test GeoDCAT-AP also with respect to its actual implementation. On behalf of the GeoDCAT-AP WG, thanks in advance for any feedback you would like to contribute. Best, Andrea ---- [1]https://lists.w3.org/Archives/Public/public-locadd/2015Mar/0001.html [2]https://webgate.ec.europa.eu/CITnet/stash/projects/ODCKAN/repos/iso-19139-to-dcat-ap/ [3]https://webgate.ec.europa.eu/CITnet/stash/projects/ODCKAN/repos/iso-19139-to-dcat-ap/browse/documentation/Mappings.md [4]https://webgate.ec.europa.eu/CITnet/stash/projects/ODCKAN/repos/iso-19139-to-dcat-ap/browse/documentation/HTTP-URIs.md ----------- CALL FOR PUBLIC REVIEW OF GeoDCAT-AP Dear Madam, Dear Sir, You are kindly invited to review the working group draft of the GeoDCAT Application Profile, an extension of the DCAT application profile (DCAT-AP) for describing geospatial datasets, dataset series, and services. GeoDCAT-AP provides an RDF syntax binding for the union of metadata elements defined in the core profile of ISO 19115:2003 and those defined in the framework of the INSPIRE Directive. The GeoDCAT-AP specification can be downloaded from: https://joinup.ec.europa.eu/node/139283#Distributions The specification is accompanied by an XSLT script, which allows the automated conversion of ISO 19139 metadata records into GeoDCAT-AP format https://webgate.ec.europa.eu/CITnet/stash/projects/ODCKAN/repos/iso-19139-to-dcat-ap/ The public review period will last until 30 August 2015. Please submit your feedback by sending comments and suggestions to the GeoDCAT-AP mailing list: dcat_application_profile-geo@joinup.ec.europa.eu. The feedback received will be discussed by the GeoDCAT-AP Working Group in early September. Final publication of application profile is foreseen for October 2015. The full text of the call is available from Joinup: https://joinup.ec.europa.eu/node/144506/ The intended use case of GeoDCAT-AP is to make spatial datasets, data series, and services searchable on general data portals, thereby making geospatial information better searchable across borders and sectors. This can be achieved by the exchange of descriptions of data sets among data portals using a common exchange format. GeoDCAT-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 four Directorates-General of the European Commission: the Joint Research Centre, DG DIGIT (ISA Programme), DG CONNECT and the Publications Office of the EU. Looking forward to receiving your feedback, The EU ISA Programme -----------
