CTS2-LE LOINC Loader

The LOINC loader is provided with 2 files that have to be obtained from LOINC downloads (Regenstrief Institute, Inc.):

1. a file that comprises the LOINC codes along with their axes (comma separated)
2. a file that defines the multi-axial hierarchy (comma separated)

The following attributes need to be set for administrative tasks and cannot be read from the files:

• the uri of the code system (aboutUri):http://loinc.org
• the alternative aboutUri of the code system (alternateAboutUri):urn:oid:2.16.840.1.113883.6.1
• the name of the code system version (resourceID): Loinc2.44
• the group name: LOINC
• the default language: en
• the name of the graph that represents the code system:urn:cts2:graph#Loinc2.44
• a description of the code system: The LOINC system (Logical Observation Identifiers Names and Codes) is a universal code system that faciliates exchange, pooling and processing of clinical and laboratory test results.

Please also note the following design activities:

• The top level concepts are defined according to the Multi-Axial Hierarchy view depicted in the Regenstrief LOINC Mapping Assistant.
• Whenever possible, a LOINC concept is weaved with a concept taken from the UCUM code system by means of a rdfs:seeAlso relation.
