Background

There are a number of additional aspects features of SNOMED CT that do not have SCTIDs or UUIDs, but which still need a URI for to be identified. URIs are required to identify these additional features to support use cases such as an OWL representation of representing SNOMED CT in OWL (e.g. to identify certain annotations) and for parts of CTS2 such as characteristicTypeIdreferring to SNOMED CT properties (e.g. characteristicTypeId) from other standards (e.g. CTS2). To address these needs requirements we define a general set of URIs identifying the RF2-based properties of Componentscomponents.

Form

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 elementinclude those described as possible values for the content type element in the File Naming Conventions

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.

Examples

The following table shows some examples of URIs for SNOMED CT RF2 properties.
