Evolving Data Models and Standards - collaborating to achieve shared understanding and semantic interoperability June 13, 2005 – MITRE, McLean, VA. Peter P. Yim Co-convener, Ontolog Forum President & CEO, CIM Engineering, Inc. (“CIM3”) (v 1.02) Presentation to the first eGov DRM Public Forum:

Evolving_Standards--PeterYim_ ppt / DRM_Public_Forum_ Who understands all of the alphabet soup? … and the jargon? ebXML CCTS ISO / IEC SCL: Simple Common Logic

Evolving_Standards--PeterYim_ ppt / DRM_Public_Forum_ answer: (probably) No One! … should we be worried? … No … but then, the immediate next moves are crucial!

Evolving_Standards--PeterYim_ ppt / DRM_Public_Forum_ We should enlist distributed collaboration (i.e. our “collective intelligence”) to the rescue.

Evolving_Standards--PeterYim_ ppt / DRM_Public_Forum_ Reuse and Semantic Interoperability Multiple working groups shouldn't have to redefine basic conceptsMultiple working groups shouldn't have to redefine basic concepts  Undermines semantic interoperability across domains and systems  Varying quality of individual models  Limits downstream extensibility Ontology-based formalizations offer more rigorOntology-based formalizations offer more rigor  Typically leverage work of broader community of interests  Designed for reuse and extensibility  Generally reflect more thorough, higher-quality modeling  Reuse of Upper and Mid-level ontologies improves semantic alignment of Domain-Level ontologies and resulting implementations
