Technologies and standards
XML provides syntax; allows users to addarbitrary structure to their documents
Resource Description Framework (RDF)Meaning expressed in sets of triples, like the
subject, verb and object of a sentence. Semantic web ontology (OWL) used to
develop domain-specific vocabularies
Simple Knowledge Organization Systems(SKOS) - Supports the use of knowledgeorganization systems (thesauri,classification schemes, and taxonomies

Benefits
Maximize outsourceability byseparating core IP (information,rules, logic, data, constraints,conditions) from coding procedures.
Extend Intellectual Property tostandard models that can be ownedand maintained locally
Youruse of open standard metadataand rule formats extends thecapability of the semantic net

State of the Semantic Web
Remember:
1. The Web was born at CERN
2. was first picked up by high energyphysicists
3. then by academia at large4. then by small businesses and start-ups
5. Big business came only later!
Network effect kicked in early
Semantic Web is now at #4, and movingto #5
