Outline of content

The Small configuration TCM comprises 3949 concepts, 4337 relationships and 10,102 descriptions, some small subsetting and crossmapping tables, and 161 ‘definitions’.

The sct_definitions table, in combination with the hierarchical structuring of the testing framework, currently comprises the explicit documentation of the individual properties that are testable via the TCM. 108 of these definition texts are prefixed by the alphanumeric pattern ‘TCM-xxxx’. This prefix identifies those concepts, or the immediate parents of those concepts, intended to be used directly as test cases. They are numbered in blocks to indicate which branch of the testing framework they reside in, but are in broken sequence (ie with gaps) to allow for some further expansion, and in no fixed order with respect to the tests within a testing block.

All new TCM concepts and linkage concepts reside under either [370115009 Special concept] or [246061005 Attribute], and (using the default build configuration) populate the 1000102 and 1000103 namespaces. Use of these namespaces is officially registered with the IHTSDO and is reserved for TCM development.

All new TCM concepts and attributes additionally have a fully specified name that carries the ‘(tcm)’ suffix.

A snapshot of the Alpha-1 release of the TCM Compliance Test Framework hierarchy is presented in the following section. This provides an overview of the range and depth of the TCMs purpose and content (Alpha-3 release):
