| Mar 12, 2007 | OUM, successor of UnitDim |
|---|---|
Within the framework of the VL-e project and Food
Informatics, we have constructed an ontology of units of measure, quantities,
dimensions and related concepts, called OUM (Ontology of Units of Measure and
related concepts). OUM is the successor UnitDim, published earlier on this site.
An ontology of units of measure and related concepts is an important resource
for unambiguous exchange and processing of quantitative information. In our work
within the project we have run into the absence of a proper, formal, digital
representation of units of measure and related concepts. In OUM, we do not claim
completeness, but the ontology covers a range of the most important units of
measure, quantities and the like, in various scientific and engineering
application domains. The ontology, implemented in OWL, is quite comprehensive
and contains over 350 units of measure and over 500 quantities. The concepts of
dimensions, systems of units, measurement scales and application areas are also
included in OUM. |

Again, we are very interested in further review and bug reports of the ontology. For downloading OUM, click here: OUM.owl. For a descriptive document about the ontology, click here: UnitDim.pdf We are looking forward to any comments and suggestions.
