Dear all, > Oddly, perhaps, schema.org seems not to care about CRS at all: > http://schema.org/GeoCoordinates Not really, they rely on us! Please, see the current issue at https://github.com/schemaorg/schemaorg/issues/113 > Can we take inspiration from the former one (geo) and admit > alternative CRSs that must be identified by virtue of the ontology > (and therefore namespace, assuming a 1-1 relationship) that is used? +1! Note that CRS could also have stable URIs to use. The French National Geographic Institute (IGN) aims to provide such stable URIs for the numerous CRSs used by French authorities. > This could do for *referencing* a CRS without ever needing a > "default". For the *description" of a CRS, I would vote to defer that > to the OGC by its existing methods, and I see no reason why that > description needs to have a linked data representation, beyond an > ontology that permits its use. Please, note that we have already a vocabulary for describing CRSs, based on ISO 19111. It is available at http://data.ign.fr/def/ignf and see http://vowl.visualdataweb.org/webvowl/#iri=http://data.ign.fr/def/ignf to see the description of the vocab in your favorite language.
