Wikidata:Relation between properties in RDF and in Wikidata
http://www.w3.org/TR/2014/REC-rdf-schema-20140225/#ch_sumproperties
The Wikidata data model is at the simplest level well-matched to RDF, as most data is encoded via an item (rdf:subject), a property (rdf:predicate) and a value for that property (rdf:object). The following table notes some of the standard properties in wikidata that match standard RDF and RDFS predicates.
Wikidata labels and descriptions are however handled separately from properties; in the RDF dump they are translated into rdfs, skos, and schema predicates directly. In particular, a Wikidata label in a given language becomes an rdfs:label, skos:prefLabel, and schema:name in the dump. An alias (alternate label) becomes a skos:altLabel. The description strings become schema:description triples.
| RDF Property name | RDF comment | RDF domain | RDF range | WD property (primary) | WD property (domain specific) |
|---|---|---|---|---|---|
| rdf:type | The subject is an instance of a class. | rdfs:Resource | rdfs:Class | instance of (P31) | vessel class (P289) |
| rdfs:subClassOf | The subject is a subclass of a class. | rdfs:Class | rdfs:Class | subclass of (P279) | parent taxon (P171) |
| rdfs:subPropertyOf | The subject is a subproperty of a property. | rdf:Property | rdf:Property | subproperty of (P1647) | |
| rdfs:domain | A domain of the subject property. | rdf:Property | rdfs:Class | expressed via property constraint (P2302) | |
| rdfs:range | A range of the subject property. | rdf:Property | rdfs:Class | expressed via property constraint (P2302) | |
| rdfs:label | A human-readable name for the subject. | rdfs:Resource | rdfs:Literal | all labels become rdfs:labels directly | |
| rdfs:comment | A description of the subject resource. | rdfs:Resource | rdfs:Literal | descriptions are represented via schema:description predicates | |
| rdfs:member | A member of the subject resource. | rdfs:Resource | rdfs:Resource | part of (P361) | transport network (P16), connecting line (P81), located in the administrative territorial entity (P131), part of the series (P179) ... |
| rdf:first | The first item in the subject RDF list. | rdf:List | rdfs:Resource | expressed via series ordinal (P1545) | |
| rdf:rest | The rest of the subject RDF list after the first item. | rdf:List | rdf:List | expressed via series ordinal (P1545) | |
| rdfs:seeAlso | Further information about the subject resource. | rdfs:Resource | rdfs:Resource | related property (P1659) | |
| rdfs:isDefinedBy | The definition of the subject resource. | rdfs:Resource | rdfs:Resource | described at URL (P973) - but this is also represented by sitelinks and external id properties | |
| rdf:value | Idiomatic property used for structured values. | rdfs:Resource | rdfs:Resource | ||
| rdf:subject | The subject of the subject RDF statement. | rdf:Statement | rdfs:Resource | ||
| rdf:predicate | The predicate of the subject RDF statement. | rdf:Statement | rdfs:Resource | ||
| rdf:object | The object of the subject RDF statement. | rdf:Statement | rdfs:Resource |
