Meaning of recommended properties on Standards #101

Open jakubklimek opened 3 months ago

jakubklimek commented 3 months ago

Motivation GeoDCAT-AP 2.0.0 specifies recommended properties for Standards:

However, even in GeoDCAT-AP examples, the recommended properties are not used, e.g. Example 25:

<http://www.opengis.net/def/crs/OGC/1.3/CRS84> a dct:Standard ;
  dct:identifier "urn:ogc:def:crs:OGC:1.3:CRS84"^^xsd:anyURI ;
  dct:title "CRS84"@en ;
  dct:type <http://inspire.ec.europa.eu/glossary/SpatialReferenceSystem> ;
  skos:inScheme <http://www.opengis.net/def/crs/OGC> ;
  skos:prefLabel "CRS84"@en .

Questions

  1. What is the meaning of recommended here? Should the properties be used with all standards mentioned in GeoDCAT-AP? e.g. with http://www.opengeospatial.org/standards/wms in the following example? 
    [] a dcat:DataService;
dct:conformsTo <http://www.opengeospatial.org/standards/wms> .
  2. Should they be used only for standards for which there are no URIs?
  3. Is there a registry of standards in which the standards are documented using the recommended properties?

Possible proposals

  1. Move recommended properties to optional properties for Standards

Since no additional feedback was received, this is resolved in sync with #109 - all properties for supporting entities, including Standards, will be optional.
