(c) Commonwealth of Australia (CSIRO), 2021
An ontology to govern Linked Data resources published within the [Loc-I](https://confluence.csiro.au/display/DIPAAnalyticHubs/Location+Integration+Capability+Loc-I) project. The primary focus is on (a) datasets composed of multiple geospatial features (objects); (b) recording relationships between features, with metadata attached to reified rdf:Statements.
Loc-I Ontology
A Loc-I Dataset is a DCAT and VOID Dataset that has been accepted by the Loc-I Registry Manager.
Membership of a loci:Dataset is (a) geo:Feature (Loc-I conformant) (b) loci:LinkingStatement (c) related types, such as PlaceNames
Loc-I Dataset
Should be implemented as a SHACL shape
A Loc-I Feature is a GeoSPARQL Feature that has at least one Geometry, one persistent identifier, and is a member of a loci:Dataset
Loc-I Feature
An RDF Statement (Subject, Predicate, Object + additional metadata) that links class instances in one Loc-I Dataset with class instances in another
Loc-I Dataset Linking Statement
A Loc-I Linkset is a specialised form of a VoID Linkset that requires the void:subjectsTarget & void:objectsTarget indicate Loc-I Datasets
Loc-I Linkset
This property is used to relate an individual feature from one geography or dataset with a feature from another geography or dataset which is intended to represent the same real-world entity. Use of loci:equivalent would allow representations using slightly different geometrical bases (e.g. surveyed geometries, aggregates of DGGS cells, aggregates of ASGS meshblocks) to be linked, in situations where a purely geometrical computation might not deduce a `geo:sfEquals` relationships because of differing precision, slivers, etc,. When the data provider's intention is that they match, then this predicate can be used to make that assertion. The provenance of the assertion maybe be recorded in the usual way in a link-set.
equivalent to
The method that was used to generate this object
This property is a property chain axiom equivalent to a chain of three properties in the PROV ontology: prov:wasGeneratedBy, prov:qualifiedAssociation and prov:hadPlan linking a prov:Entity (the thing generated) to a prov:Plan (the thin instruction generation - the method) via a prov:Activity (the generating event) and a prov:Association that the prov:Activity has linking it to the prov:Plan.
had generation method
The context resource contains the target resource, in some geospatial, logical, ownership, governance, jurisidictional or compositional sense. This predicate provides a convenient generalized or super-property-of containment relations with more specialized semantics. It may be useful in formulating some generalized SPARQL queries where any kind of containment relationship is intended. Note that this property is **not transitive** though some sub-properties may be.
has part
The context resource is a member of the target resource (a collection, aggregate or composite)
is member of
The context resource is part of the target resource, in some geospatial, logical, ownership, governance, jurisidictional or compositional sense. This predicate provides a convenient generalized or super-property-of contained-by relations with more specialized semantics. It may be useful in formulating some generalized SPARQL queries where any kind of containment relationship is intended. Note that this property is **not transitive** though some sub-properties may be.
is part of
In the context of Loc-I datasets, `dcterms:type` is used for an additional classifier, such as a place-type or meshblock-category. The value should be taken from a controlled-vocabulary, and may be expressed as a `skos:Concept` or an `rdfs:Class` or some other kind of resource providing it is from a well-governed source.
