CTS2-LE UCUM Loader

The UCUM loader imports a terminology that comprises the most common units of measurement contemporarily used in international science, engineering and business. The loader maps the knowledge contained in the source .tsv-file to the entities of the CTS2-information model. There are attributes that cannot be derived from the file and need to be defined manually. Among these attributes are:

• the uri of the code system (aboutUri): http://unitsofmeasure.org/trac
• the alternative uri of the code system (alternateAboutUri): http://unitsofmeasure.org/trac
• the name of the code system version (resourceID): UcumCodeSystem2013
• the group name: UCUM
• the default language: en
• the name of the graph that represents the code system: http://unitsofmeasure.org/trac#UcumCodeSystem

When UCUM is loaded together with the LOINC terminology, the unit of a LOINC concept is referenced in the UCUM code system by means of a 'rdfs:seeAlso' relation.

Further instructions on how to enable the import of UCUM during the installation process can be found here.
