OGC Linked Data API Profile

A profile (of various Semantic Web standards) that provides a data model for OGC LD API systems.

This profile specifies the "shape" of data elements needed for instnaces of OGC APIs but additionally requires certain Linked Data characteristics of data. The result is a requirement for "OGC LD API" data that is a superset of OGC API data and a subset of (the infinite) Linked Data world.

The classes of data required for an OGC API are:

1. LandingPage
2. FeatureCollections
3. Feature

Our interpretation of this is that the following Semantic Web / Linked Data classes of object correspond to those above:

1. dcat:Dataset (and possibly a dcat:DataService but this isn't implemented yet) - as per DCAT
2. geo:FeatureCollection - as per GeoSPARQL 1.1
3. geo:Feature - as per the original GeoSPARQL

The OGC LD API requires data objects in of these classes to have certain properties - titles, IDs, geometries etc. - and a SHACL Shape validator is provided to validate that data to be used by API instances actually does contain these elements.
