In philosophy, a process ontology refers to a universal model of the structure of the world as an ordered wholeness.
However, fundamental process ontologies have become more important in recent times, because the progress in the discovery of the foundations of physics has spurred the development of a basic concept able to integrate such boundary notions as "energy," "object", and those of the physical dimensions of space and time.
This ontology provides a vocabulary of classes and relations for concepts at the ground level of event-instances, object-instances, and timepoints.
The results of the project SUPER include the UPO and a set of ontologies for processes and organizations.
The main target of DDPO is tasks, namely the types of actions, their sequencing, and the controls performed on them.
The purpose of oXPDL is to model the semantics of XPDL process models in standardized Web ontology languages such as OWL and WSML, while incorporating features of existing standard ontologies such as PSL, RosettaNet, and SUMO.
GFO includes elaborations of categories like objects, processes, time and space, properties, relations, roles, functions, facts, and situations.
[19][20][21] The m3po ontology unifies both internal and external business processes, combining reference models and languages from the workflow and choreography domains.
The related ontology m3pl, written in PSL using the extension FLOWS (First Order Logic for Web Services), enables the extraction of choreography interfaces from workflow models.
