Para explanar como a WS se relaciona com cada sistema da AI, foram consideradas as tecnologias apontadas pelo W3C (XML, RDF, RDF Schema, OWL, SPARQL e SWRL), bem como algumas aplicacoes que utilizam tecnologias da WS e que sao objetos de estudo da Ciencia da Informacao (Knowledge Graph, Rich Snippets, Linked Data, Explorator e Europeana Data Model--EDM).
Los vocabularios y ontologias mas usados son: DUBLIN CORE, BIBO, BIO, FOAF, FRBR, FRAD, FRSAD, IFLA, ISBD, INTERMARC, MADS / RDF, XML EAD, OAI_ORE, RDF, RDF SCHEMA, ORG, OWL, RDA, SKOS, WGS84 y EVENT.
For that rationale, the RDF schema is needed to define resource varieties and property names.
Structured formats for binding the elements of a metadata schema are XML, XML Schema, RDF, RDF Schema and OWL.
OntoRelfinder [9] also precalculates and materializes path expressions, but the scope is within the triples of the RDF schema classes.

Two types of standard are required, one for describing ontology such as the OWL (OWL 2 is now recommended by W3C [25]), and the other for annotations such as the W3C's RDF schema [26].
Resource description framework (RDF) code illustrates the triples format, RDF schema vocabulary, the web ontology language (OWL), reification, named graphs, graph patterns and querying from multiple graphs.
The language supports a second-order syntax, which is efficiently translated into sets of first-order logic rules using metadata, where variables can range over classes and properties, so that reasoning over the RDF schema can be performed.
