ISO 18629 (Process Specification Language)
Michael Grüninger has been the project leader for the Process Specification Language
project at the National Institute of Standards and Technology.
of the Process Specification Language project is the development of a
common ontology for process modelling which
enables the interoperability of manufacturing process
descriptions between manufacturing engineering and business software
such as process planning, scheduling workflow, business process reengineering,
and project management.
PSL has been demonstrated in several software interoperability scenarios:
PSL: A semantic domain for flow models,
PSL: Principles and Applications
PSL for project scheduling information exchange
Ontologies for integrating engineering applicatons
Semantic Integration through Invariants
Two companies are currently building commercial software tools to manipulate
PSL process descriptions.
Within the academic and industrial research communities, PSL is serving as
the logical foundation for the Semantic Web Services Ontology, which was
submitted to the World Wide Web Consortium. This ontology
addresses the need for richer semantic specifications of
web services, based on a comprehensive representational framework that spans
the full range of service-related concepts.
In 2005, PSL was officially published as an
International Standard with the name ISO 18629
by the Joint Working Group 8 of Sub-committee 4
Industrial data and Sub-committee 5 Manufacturing integration of
Technical committee ISO TC 184, Industrial automation systems and
integration of the International Organization of Standardization.
It is the first engineering standard based on mathematical logic.
