The presentation covered:
The problem of ambiguous units — why existing approaches (code lists, symbols, names) fail for reliable scientific data exchangeUnitsML's approach — structured models for encoding units, quantities, and dimensionsUnitsDB — the comprehensive database of scientific units, from SI base units to non-SI unitsStandards governance — the transition from NIST through OASIS to CalConnect TC UNITSFuture directions — international alignment with ISO, IEC, and BIPM towards a "Digital SI"
Early UnitsML presentation at the metadata registries forum in Santa Fe, NM — one of the first public introductions of the project.
January 2003 · PPT
Peer-reviewed paper in the NIST Journal of Research describing how UnitsML improves data exchange by embedding unambiguous unit definitions in markup languages.
January–February 2010 · NIST JRES · PDF
Official guidelines document covering how to use UnitsML in practice — writing valid markup, choosing appropriate elements, and incorporating UnitsML into other formats.
Version 1.0-wd01 · PDF
Early draft of the UnitsML usage guidelines, providing context on the design decisions and intended usage patterns.
Draft 0.4.2 · DOC
