Collaborative development of ontologies

The ontologies used in the project were used for two purposes: publicly define shared vocabularies of the project domain so that agents can use them in the interaction; as a way for an agent to discover other agents providing desired services and information.

The project decided to use DAML+OIL as the ontology representation framework given the current and widely disseminated trend towards DAML+OIL. This decision has shown to be well justified since W3C has chosen DAML+OIL as the basis for their Ontology Representation Standard OWL (Web Ontology Language). DAML+OIL framework and language has the following main characteristics:

The domain is modelled in terms of classes, properties and objects. A class may be defined as the subset of the elements of another class that have a specified set of properties. Properties exist outside the scope of the class but can be associated with classes. Unlike many other object-oriented approaches, properties in DAML+OIL may be hierarchically organised. Each property has domain and range. The property domain is the set of classes to which it can be applied. The range is the set of values the property may have. These can be specified as a class or as a data type.
