The term ontology has its origin in philosophy. In computer science and information science, an ontology is a formal naming and definition of the types, properties, and interrelationships of the entities that really or fundamentally exist for a particular domain of discourse.
The Design Built Process ontology (DBP) has been designed to facilitate accurate and complete exchange of Design Built Process information.
The Design Built Process ontology (DBP) is based on the Process Specification Language (PSL). There are four primitive classes in the ontology of PSL Core, ACTIVITY, ACTIVITY_OCCURENCE, TIMEPOINT and OBJECT.
Roles descriptions are based on the General Formal Ontology (GFO) .
Each class can have several types (individuals in the ontological vocabular).
