An ontology describing specialised spatial and dataset classes for the Location Integration Capability (LOC-I) projects. LOC-I is one of the Data Integration Partnership for Australia (DIPA) https://www.pmc.gov.au/public-data/data-integration-partnership-australia projects, in this case involving CSIRO, GA, ABS & DoEE.
This ontology will subclass the GeoSPARQL Feature class by adding constraints to ensure that all geo:Feature objects published within LOC-I datasets contain certain relations, for example, a link from the Feature to a dcat:Dataset object that contains it, thus making clear what Dataset the feature is within.
The ontology will also subclass dcat:Dataset (v2 of DCAT) to create a class called a "Linkset" which is a Dataset used to publish links between other datasets. A Linkset will require certain metadata not typically found in dcat:Datasets, principally notes on the methodology used to form the links between separate datasets. While the Semantic Web allows for links between essentially any two things to be declared, LOC-I Linksets will be restricted to certain authorised link publishers.
In addition to being an ontology, the LOC-I Ontology is also a Profile, as described by the emerging W3C Profiles Ontology (https://w3c.github.io/dxwg/profilesont/) which profiles both GeoSPARQL and DCAT. This is mentioned for the WG might be interested to see what the implications of being a formalised ontology are in the future, unknown at present.
