An ontology is a formal specification of a conceptualization,usually related to a specific domain of knowledge like library and information science.The metadata application profile along with the documentation of its abstract model can be thought of a primitive ontology of a specific implementation. Classification themes and thesaurus,which have been used for a long time in the library and information arena,are also a source of formal ontologies.After formalization processing and encoded with standard ontology languages,these kinds of concept systems can be very useful to establish a metadata service based on ontology services and fulfill the high level interoperability of digital libraries.
