Hi Andrea, Thanks a lot for pointing this! With the amount of work (and review) that's already gone into DCAT-AP and GeoDCAT-AP, I'd suggest we follow the pattern without questioning it - especially if some of us already prefered it ;-) Best, Antoine On 11/27/15 1:53 PM, Andrea Perego wrote: > Dear WG, > > Apologies for jumping in your discussion. but since your use case is > about GeoDCAT-AP, I thought it was relevant to mention that DCAT-AP > (and therefore also GeoDCAT-AP) supports the possibility of specifying > the metadata standard / application profile), using exactly the > solution proposed by Antoine - i.e.: > > my:CatalogRecord a dcat:CatalogRecord ; > foaf:primaryTopic my:Dataset ; > dct:conformsTo <metadata standard / application profile> . > > Best, > > Andrea > > > On Fri, Nov 27, 2015 at 9:50 AM, Antoine Isaac <aisaac@few.vu.nl> wrote: >> Hi Riccardo, >> >> Sorry for the late response.
