rdfs:label a human-readable name for the subject rdfs:comment a description of the subject resource rdfs:member a member of the subject resource rdfs:seeAlso further information about the subject resource rdfs:isDefinedBy the definition of the subject resource. This vocabulary is used as a foundation for RDF Schema, where it is extended.
When used as such a property is a predicate (see also RDF: reification). rdfs:domain the rdfs:domain of an rdf:Property declares the class of the subject in a triple whose predicate is that property. rdfs:range the rdfs:range of an rdf:Property declares the class or datatype of the object in a triple whose predicate is that property.
A semantic triple, or RDF triple or simply triple, is the atomic data entity in the Resource Description Framework (RDF) data model. [1] As its name indicates, a triple is a sequence of three entities that codifies a statement about semantic data in the form of subject–predicate–object expressions (e.g., "Bob is 35", or "Bob knows John").
RDF/XML is a syntax, [1] defined by the W3C, to express (i.e. serialize) an RDF graph as an XML document. RDF/XML is sometimes misleadingly called simply RDF because it was introduced among the other W3C specifications defining RDF and it was historically the first W3C standard RDF serialization format.
In computing, Terse RDF Triple Language (Turtle) is a syntax and file format for expressing data in the Resource Description Framework (RDF) data model. Turtle syntax is similar to that of SPARQL, an RDF query language.
These languages support querying of both data and schema. RQL, an acronym for RDF Query Language, is known for using types defined in RDF schemas (RDFS) to query the schema class hierarchy and to support data querying by type. RQL is considered more expressive than the SPARQL family of languages, but has been criticized for too many features ...
A triplestore or RDF store is a purpose-built database for the storage and retrieval of triples [1] through semantic queries.A triple is a data entity composed of subject–predicate–object, like "Bob is 35" (i.e., Bob's age measured in years is 35) or "Bob knows Fred".
Using RDFS it is for example possible to create hierarchies of classes and properties. Web Ontology Language (OWL) extends RDFS by adding more advanced constructs to describe semantics of RDF statements. It allows stating additional constraints, such as for example cardinality, restrictions of values, or characteristics of properties such as ...
