Description

An ontology to govern Linked Data resources published within the 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 Dataset^c

URI	`http://linked.data.gov.au/def/loci#Dataset`
Description	A Loc-I Dataset is a DCAT and VOID Dataset that has been accepted by the Loc-I Registry Manager.
Super-classes	rdf:Bag^c void:Dataset^c dcat:Dataset^c
Restrictions	dcterms:issued exactly 1 dcterms:publisher exactly 1 org:Organization^c dcterms:modified exactly 1 dcterms:title exactly 1 dcat:contactPoint min 1 rdfs:member min 1
Sub-classes	loci:Linkset^c
In range of	loci:isMemberOf^op

Loc-I Feature^c

URI	`http://linked.data.gov.au/def/loci#Feature`
Description	Should be implemented as a SHACL shape
Super-classes	geo:Feature^c
Restrictions	loci:isPartOf^op only geo:Feature^c dcterms:identifier min 1 loci:hasPart^op only geo:Feature^c geo:hasGeometry min 1 geo:Geometry^c

Loc-I Dataset Linking Statement^c

URI	`http://linked.data.gov.au/def/loci#LinkingStatement`
Description	An RDF Statement (Subject, Predicate, Object + additional metadata) that links class instances in one Loc-I Dataset with class instances in another
Super-classes	rdf:Statement^c
Restrictions	loci:isMemberOf^op exactly 1 loci:Linkset^c rdf:object exactly 1 rdf:predicate min 1 loci:hadGenerationMethod^op exactly 1 prov:Plan^c rdf:subject exactly 1

Loc-I Linkset^c

URI	`http://linked.data.gov.au/def/loci#Linkset`
Description	A Loc-I Linkset is a specialised form of a VoID Linkset that requires the void:subjectsTarget & void:objectsTarget indicate Loc-I Datasets
Super-classes	loci:Dataset^c void:Linkset^c
Restrictions	rdfs:member only loci:LinkingStatement^c

URI http://linked.data.gov.au/def/loci#equivalentTo

Description

URI	`http://linked.data.gov.au/def/loci#equivalentTo`
Description	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.

type^op

URI	`http://purl.org/dc/terms/type`
Description	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.

had generation method^op

URI	`http://linked.data.gov.au/def/loci#hadGenerationMethod`
Description	The method that was used to generate this object
Domain(s)	rdf:Statement^c
Range(s)	prov:Plan^c

has part^op

URI	`http://linked.data.gov.au/def/loci#hasPart`
Description	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.
Domain(s)	geo:SpatialObject^c
Range(s)	geo:SpatialObject^c

is member of^op

URI	`http://linked.data.gov.au/def/loci#isMemberOf`
Description	The context resource is a member of the target resource (a collection, aggregate or composite)
Range(s)	loci:Dataset^c

is part of^op

URI	`http://linked.data.gov.au/def/loci#isPartOf`
Description	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.
Inverse properties	loci:hasPart^op
Domain(s)	geo:SpatialObject^c
Range(s)	geo:SpatialObject^c
