Dear Frans, > Thank you for sharing this. It is an impressive undertaking, I do hope > you will let us know when it is finished. Yes, we will naturally. > Do you plan to include links to the OGC CRS URIs in your CRS > vocabularies? As far as I know, those URIs do not resolve to RDF (yet), > but they can be expected to be widely used identifiers of CRSes. This would be a good idea indeed. I tried to look up what CRS are already been given an id by OGC, but from http://www.opengis.net/def/crs/ and I just see some examples coming either from the EPSG or OGC authority. I think historically OGC used to have URNs to identify CRS but the move to use URL is recent, right? Do you know where can I have an exhaustive list of resources that would be of type http://www.opengis.net/def/dataType/OGC/1.1/crsURI? > About your remark about allowing a geometry to have different CRSes: Do > you mean that you see a geometry as a real world phenomenon that can > have multiple data encodings? No, we are just saying that a geometry depends on a CRS to be correctly interpreted, and that CRS is better been made explicit, which is generally not the case for barely all geo-localized resources published by the French government.
