In particular, error handling and content negotiation will need to be addressed in September. This is the very first version of the prototype and some features requires further refinements. There are also plans to add HTML+RDFa, starting from September. About the output formatĬurrently, the conversion tool supports different RDF serialisations of DCAT-AP and GeoDCAT-AP - more precisely, RDF/XML, Turtle, N3, N-Triples and JSON-LD. Alternatively, the tool works also on static files including metadata records.

Subsequently, it uses the GeoDCAT-AP XSLT stylesheet to transform ISO 19139 records into (Geo)DCAT-AP. The experimental conversion tool for GeoDCAT-AP uses the standardised CSW HTTP Request interface (using the GetRecords or GetRecordById operations) to retrieve descriptive metadata in ISO 19139 format. The Joint Research Centre developed in the context of the ARE3NA ISA Action an XSLT stylesheet to do an automatic conversion from ISO 19139 to (Geo)DCAT-AP. The conversion tool allows the automatic conversion with very little additional investment from data providers. Providing geospatial metadata in this additional syntax can aid data discovery with a wider group of potential data users. The GeoDCAT-AP specification provides an alternative RDF syntax for metadata according to the INSPIRE Metadata Regulation and the ISO19115 Core profile. The CSW provides an HTTP interface allowing machine readable metadata to be requested from a server in ISO19139 xml format. To date, search services for spatial information, such as INSPIRE discovery services, are often based on the CSW standard (e.g. The tool provides a service that is capable of retrieving metadata from an OGC Catalogue Service for the Web ( CSW) server and converting it into the WC3’s linked data’s Resource Description Framework (RDF) in one of several serialisations according to either the DCAT-AP or GeoDCAT-AP.

You can access the source code and preliminary documentation and see an online demo that has been set up in collaboration with SEMIC (ISA Action 1.1), who is leading the overall work on DCAT-AP. It 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. GeoDCAT-AP is an extension of DCAT-AP for describing geospatial datasets, dataset series, and services. In the context of the ARE3NA Action funded by the ISA Programme, the Joint Research Centre has developed an experimental tool to convert metadata from ISO 19115/19139, the standards widely used in the geospatial domain, to DCAT-AP or its geospatial extension GeoDCAT-AP, the standards used for open data portals in Europe. Making geospatial information available through open data portals increases its potential to be found and consumed not only in the geospatial, but also in other sectors (e.g.
