7 years ago We are using GeoSPARQL as upper ontology for spatial object / feature types. Issue #31 discusses if that alignment should be applied for all spatial object / feature types or only a subset.

Description
Spatial object / feature types of INSPIRE application schemas are instances of the ISO 19109 GF_FeatureType meta-class. In the GML encoding, this relationship is expressed by all INSPIRE spatial object / feature types being in the substitution group of gml:AbstractFeature. The same is true for the GML encoding of feature types from other application schemas.
This approach supports working with any feature type, for example writing rules that must be supported by any feature, specifying service interfaces that manage any feature, and encoding data sets with any feature as member.
The question is if a similar approach can be usefully applied to INSPIRE RDF schemas and how it should look like.
Some further background information:
NOTE: the General Feature Model vocabulary has not been published yet (8th of January, 2016), but a draft version is available at https://github.com/ISO-TC211/GOM/blob/master/isotc211_GOM_harmonizedOntology/19109/2005/iso19109GeneralFeatureModel.owl. We assume that once finalised, the vocabularies will be published on the ISO/TC 211 website as the base URI of the vocabulary suggests. There is also a new version of ISO 19109 (ISO 19109:2015, published in December 2015) for which no vocabulary is available yet. However, as INSPIRE uses ISO 19109:2005 this should not be an issue.
Discussion Item
Which vocabularies – in addition to the ones that were already mentioned - define classes that implement the semantics of ISO 19109 GF_FeatureType? These vocabularies would be candidates for upper ontologies of INSPIRE RDF schema.
