RDF is a directed graph composed of triple statements. An RDF graph statement is represented by: (1) a node for the subject, (2) an arc from subject to object, representing a predicate, and (3) a node for the object. Each of these parts can be identified by a Uniform Resource Identifier (URI). An object can also be a literal value.
(Turtle examples are also valid Notation3). The example encodes an RDF graph made of four triples, which express these facts: The W3C technical report on RDF syntax and grammar has the title RDF/XML Syntax Specification (Revised). That report's editor is a certain individual, who in turn Has full name Dave Beckett. Has a home page at a certain ...
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").
TriG is a serialization format for RDF (Resource Description Framework) graphs. It is a plain text format for serializing named graphs and RDF Datasets which offers a compact and readable alternative to the XML-based TriX syntax.
To enable the encoding of semantics with the data, technologies such as Resource Description Framework (RDF) [2] and Web Ontology Language (OWL) [3] are used. These technologies are used to formally represent metadata. For example, ontology can describe concepts, relationships between entities, and categories of things.
RDF Schema (Resource Description Framework Schema, variously abbreviated as RDFS, RDF(S), RDF-S, or RDF/S) is a set of classes with certain properties using the RDF extensible knowledge representation data model, providing basic elements for the description of ontologies. It uses various forms of RDF vocabularies, intended to structure RDF ...
It is a line-based, plain text serialisation format for RDF (Resource Description Framework) graphs, and a subset of the Turtle (Terse RDF Triple Language) format. [ 1 ] [ 2 ] [ 3 ] N-Triples should not be confused with Notation3 which is a superset of Turtle.
Initially developed as fifteen terms in 1998 the set of elements has grown over time and in 2008 was redefined as an Resource Description Framework (RDF) vocabulary. [1] Designed with minimal constraints, each Dublin Core element is optional and may be repeated. There is no prescribed order in Dublin Core for presenting or using the elements.
