Industrial automation systems and integration — Exchange of characteristic data — Part 20: Concept dictionary resolution services

ISO/TS 29002-20:2010 specifies an interface to retrieve information from a concept dictionary. Three sets of capabilities, called "services", are defined:

• Location Service: given a registration authority identifier, returns location on the Internet of Terminology and Ontology servers for the registration authority;

• Terminology Service: searches for concepts, languages, and other elements of the dictionary based on a rich set of keywords, search criteria, and expressions; given an international registration data identifier (IRDI) in the format defined in ISO/TS 29002-5, retrieves terminological information;

• Ontology Service: retrieves ontological information about a concept based on the concept's IRDI.
