[cat-interop] Metadata link types vocabulary proposal

[Paul van Genuchten]

I support Stephan at this point. The semantic web can be a big consumer
of spatial data services, if we're able to optimally embed our data in
it. Linking to controlled vocabularies by url is a big facilitator.

Sure i see the point of having a urn structure as
{provider}:{type}:{identifier}:{version}. But this can also be managed
in a (skos) vocabulary-identifier-as-url by using identifiers like:

for example:
http://osgeo.org/vocab/service/ogc/wms/1.1
http://osgeo.org/vocab/service/opensearch/opensearch/2.0

and

http://osgeo.org/vocab/mediatype/esri/shapefile/1.0
http://osgeo.org/vocab/mediatype/ogc/gml/2.0
http://osgeo.org/vocab/mediatype/w3c/json-ld/1.0

or

http://osgeo.org/vocab/service#ogc_wms_1_1
http://osgeo.org/vocab/mediatype#ogc_gml_2_0

At this point we should consider if osgeo.org is the best place to set
up such a service/vocab, as this is more a data-matter then a software
matter. Should we connect with geovocab, w3c/ogc, dbpedia to have this
set up?

If we feel osgeo.org is a good place, let's post about it in the
request-list...
