Geosparql context/namespace to RDF rather than doc #96

Closed jyucsiro closed 4 years ago

jyucsiro commented 4 years ago

Looking at this context (https://opengeospatial.github.io/ELFIE/json-ld/elf.jsonld) ... and doing some tests, it appears that http://www.opengeospatial.org/standards/geosparql is used rather than http://www.opengis.net/ont/geosparql#

It would be better to use http://www.opengis.net/ont/geosparql# as this can then be used as the namespace to the GeoSPARQL ontology, which can be loaded in a tool chain.

So I'd suggest one change in that context definition shown here:

   "gsp": "http://www.opengis.net/ont/geosparql#",

Maybe this is should be an issue in ELFIE repo? (also examples need to use the new URLs to the contexts)...

I would +1 (we use http://www.opengis.net/ont/geosparq in our examples). But related to issue #67, I remember there was a discussion in November Toulouse TC during the SDWIG session about the pattern to be used within OGC NA (to have a coherence in URI patterns of all ontologies exposed at OGC level). @afeliachi may be able to provide more details on this

afeliachi commented 4 years ago

yes this was one of the questions raised in Toulouse, the answer wasn't very clear regarding Geosparql, as it is a "real" owl ontology & doesn't conform to the URI scheme of OGC NA. But what is sure is that http://www.opengeospatial.org/standards/geosparql is not correct URI for the ontology, and that the current one is http://www.opengis.net/ont/geosparql#

It's been changed in all the contexts.
