2.5 URIs for Properties

There are additional aspects of SNOMED CT that do not have SCTIDs but still need a URI for use cases such as an OWL representation of SNOMED CT (to identify certain annotations) and for parts of CTS2 such as characteristicTypeId. To address these needs we define a general set of URIs identifying the RF2-based properties of Components.

The URI space for these properties follows the pattern:

http://snomed.info/field/{tableName}.{fieldName}

Valid table names are as described for Data Files with respect to the _ContentType element¹ in the File Naming Conventions for RF2. Note, these URIs identify the property itself, not the value or values that may be associated with the property.
