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):

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.
