Abstract
System development involves the integration of different data types and modeling tools that were developed independently to address specific engineering challenges. These tools use different modeling languages, data formats, structures, and processes to represent data related to the system model. Currently, data exchange and combination are not possible due to the absence of adequate exchange standards. However, the Department of Defense Digital Engineering Strategy set goals to enable data exchange and usage. In 2022, Vaneman, Carlson, White, and Stone developed the Marine Corps Land Domain (MCLD) Ontology and conceptual data model (CDM) to facilitate this data exchange. This research evaluated the MCLD Ontology and CDM to determine their completeness. The data contained in the acquisition documentation was extracted and mapped to the entities defined in the MCLD Ontology. The research confirmed that MCLD Ontology and CDM could fully decompose the entire MCLD and identified several benefits, including containing critical acquisition details in one location, identifying the authoritative source of truth for each data element, and providing real-time status for all stakeholders. The MCLD Ontology and CDM can be used by all services on any type of acquisition program, from large ACAT I systems entering the acquisition process to small ACAT III programs that are close to the end of their program lifecycle.
