Jim Logan
Ontology Platform SIG Co-Chair
Herndon, Virginia, United States
Summary
👤
SeniorJim Logan is a realist ontologist and systems architect with 11 years of experience helping organizations achieve semantic clarity and interoperable systems. He designs foundational models that constrain interpretation so terms, diagrams, and data align with stakeholder intent, and he’s known for running live modeling sessions that produce semantically rigorous representations used to define APIs, standards, and generated code. Jim co-chairs multiple OMG working groups and leads governance and technical efforts at the Industrial Ontologies Foundry, shaping initiatives like SysML v2, KerML, and the IOF core ontology. As founder and chief ontologist of Ontogenesis Solutions, he focuses on problems where schema-based approaches fail—multi-party exchange, product lifecycle integration, and digital engineering transformation. His work blends formal semantics, multi-level theory, and practical tooling to deliver lifecycle interoperability rather than isolated models. Based in Herndon, VA, he combines standards leadership with hands-on modeling practice, often surfacing and resolving subtle conceptual ambiguities teams didn’t realize were causing integration failures.
