Table of Contents


Participation in the OASIS QUOMOS TC is open to all interested parties, including developers and users of information models or applications (e.g., document markup and data exchange) that require an unambiguous definition of units in digital form. Contact member-services@oasis-open.org for more information on joining the TC.


The OASIS Quantities and Units of Measure Ontology Standard (QUOMOS) Technical Committee works to develop an ontology to specify the basic concepts of quantities, systems of quantities, and systems of measurement units and scales, various base dimensions and units of the SI system, metric prefixes (nano-, micro-, milli-, kilo-, ...), rules for constructing various derived units, and designations of the most common derived units (joules, watts, ...) for use across multiple industries.

For more information on QUOMOS, see the TC Charter. (A Chinese translation of the TC Charter is also available.)
