NIST Support for Dimensional Metrology Interface Standards The “interoperability problem” System users cannot easily and cheaply build systems from components Component vendors have to support many different proprietary interface languages Measurement quality suffers The interoperability solution: concurrent development of Interface standards: Timely, unambiguous, sufficiently functional, and consensus-based Implementations: Timely, compliant, fully functional, interoperable, and performed by a critical mass of vendors worldwide Tests: Product must pass conformance and interoperability tests for purchase 28/04/2005 John Horst NIST

NIST Support for Dimensional Metrology Interface Standards Provide leadership, analysis, consultation, and testing support; working through AIAG MIPT I++ & IA.CMM DNSC & EDUG Regular and frequent implementers meetings to ensure Compliant implementations Consistent, unified, and documented feedback to spec writers to ensure unambiguous and sufficiently functional spec 28/04/2005 John Horst NIST

NIST Support for Dimensional Metrology Interface Standards Write test suites consisting of test cases, test utilities, test artifacts, and example code modules for enabling new implementations Public interoperability tests to further encourage compliant implementations and unambiguous spec 28/04/2005 John Horst NIST

I/F Standards Test Development NIST Validation Testing Validation Testing Interoperability Testing Can this specification support what my software can do? Why aren’t our two implementations communicating well? Conformance Testing How do I need to augment my product to conform? How well does this vendor’s software conform to the standard? Specification Writers Software and Hardware Vendors
