A Transformation Process for Generating an Extensible Markup Language (XML) Schema from a Formal Ontology for Practical Application in C2SIM Implementations

摘要

A Simulation Interoperability Standards Organization (SISO) Product Development Group (PDG) is developing a standard for Command and Control System to Simulation System Interoperation (C2SIM). The C2SIM standard will improve upon and replace the current SISO standards Military Scenario Definition Language (MSDL; SISO-STD-007-2008) and Coalition Battle Management Language (C-BML; SISO-STD-011-2014). Current work in the PDG is specifying a core logical data model ontology addressing key areas of C2-to-Simulation interoperation such as initialization and tasking/reporting as well as transformation of the ontology data model to an Extensible Markup Language (XML) schema for implementation. This paper describes the transformation process of interpreting the ontology structures and generating associated XML Schema language constructs to support practical application of the standard. Certain restrictions are imposed on the XML Schema language constructs generated by the transformation process in order to make implementation of software for reading and writing XML documents conforming to the generated schema as simple as possible. The transformation relies on particular patterns found in a specific representation of the ontology; namely, the Resource Description Framework (RDF) XML (rdf/xml) format produced by the open-source Protege ontology editing tool developed by Stanford University.
