Common Ontologies for Semantic Web Domain Modeling

Saturday, October 11th, 2008

Below is a list of the ontologies I am currently using for semantic web domain modeling.

Core Ontologies

  • RDF Vocabulary The RDF Schema for the RDF vocabulary defined in the RDF namespace xmlns:rdf=”http://www.w3.org/1999/02/22-rdf-syntax-ns#”
  • RDFS The RDF Schema vocabulary xmlns:rdfs=”http://www.w3.org/2000/01/rdf-schema#”
  • XML Schema xmlns:xsd=”http://www.w3.org/2001/XMLSchema#”
  • OWL Web Ontology Language xmlns:owl=”http://www.w3.org/2002/07/owl#”
  • Dublin Core xmlns:dc=”http://purl.org/dc/elements/1.1/”
  • Dublin Core Metadata Terms xmlns:dct=”http://purl.org/dc/terms

ISO-15926

Sunday, June 29th, 2008

The ISO-15926 standard is titled: “Industrial automation systems and integration—Integration of life-cycle data for process plants including oil and gas production facilities“. One of its main requirements was that the scope of the data model covers the entire lifecycle of a facility (e.g. oil refinery) and its components (e.g. pipes, pumps and their parts, etc.)

The data model that has evolved is an RDF/OWL ontology. Its development and evolution has set some important precedents that other engineering and construction projects such as the development of the Common Inspection and Test Plans can learn from. These include:

  • The use of OWL to model concepts and the potential reuse of concepts already identified by ISO-15926 and modeled in OWL.
  • The construction of OWL ontologies through community participation.
  • Public sharing of web based ontologies in order to speed up the adoption of standardized concepts.
  • The development of a Semantic Web Ontology browser.
  • Provisioning for individual companies to provide their own customizations.

Wikipedia provides overviews of both ISO-15926 and ISO-15926 WIP (Work In Progress).

15926.ORG is a wiki based site providing a Knowledge Base dedicated to the practical implementation of, and information about ISO 15926. It includes an ISO 15926 General Introduction.
