Hi, Frans. > [snip] > > As for time, I do not yet see a requirement like the Spatial Metadata > requirement for temporal data, but I think there could be.

Just to note that we do have a metadata-related use case including temporal resolution and temporal reference systems in the requirements. It's the in Section 4.42: http://w3c.github.io/sdw/UseCases/SDWUseCasesAndRequirements.html#h-geospatialextensionstodomainindependentmetadataschemas The requirements are listed in the UC description. BTW, these are still open issues in the work on GeoDCAT-AP described by the UC. The GeoDCAT-AP WG is currently maintaining an XSLT to transform ISO 19139 metadata records into RDF, and mappings for the metadata elements under discussion are still missing (along with the one concerning CRSs): https://webgate.ec.europa.eu/CITnet/stash/projects/ODCKAN/repos/iso-19139-to-dcat-ap/ >From what reported by members of the GeoDCAT-AP WG, it is apparent that many organisations dealing with spatial data and their publication on cross-domain data catalogues are using provisional approaches to deal with this problem, while waiting for the publication of best practices. Cheers, Andrea
