Process Specification Language
The Process Specification Language (PSL) is a set of logic terms used to describe processes. The logic terms are specified in an ontology that provides a formal description of the components and their relationships that make up a process. The ontology was developed at the National Institute of Standards and Technology (NIST), and has been approved as an international standard in the document ISO 18629.
The Process Specification Language is used for the representation of basic manufacturing, engineering and business processes. In the manufacturing domain, PSL’s objective is to serve as an interlingua for integrating several process-related applications throughout the manufacturing process life cycle. The process-related applications include production planning, process planning, workflow management, and project management.
The foundation of the ontology is a set of primitive concepts (activity, object, timepoint, and relationship), functions (beginof, endof), and relations (participates-in, between, before, occurring-at) that are common to all types of manufacturing processes. This core ontology is then used to describe more complex concepts. The ontology uses the Common Logic Interchange Format (CLIF) to represent the concepts, functions, and relations.
