In addition to the standard properties, the following properties are defined for SNOMED CT:
Property | Data Type | Comments |
inactive | boolean | Whether the code is active or not (defaults to false). This is derived from the active column in the Concept file of the RF2 Distribution (by inverting the value) |
sufficientlyDefined | boolean | True if the description logic definition of the concept includes sufficient conditions. This is derived from the definitionStatusId value in the Concept file of the RF2 distribution (i.e. If 900000000000073002 |Sufficiently defined concept definition status| then true). |
moduleId | code | The SNOMED CT concept id of the module that the concept belongs to. |
normalForm | string | Generated Normal form expression for the provided code or expression. |
In addition, any SNOMED CT relationships where the relationship type is subsumed by 410662002 |Concept model attribute| automatically become properties. Properties that represent SNOMED CT concept model attributes are referred to using their concept id, rather than their human readable term.
For example, the laterality property is represented using the conceptId for 272741003 |Laterality|:concept id '272741003', rather than the term 'laterality':
Property | Data Type | Comments | ||
272741003 | code | The value of the laterality attribute in the definition of the given code or expression. | 272741003 | code The equivalent URI for the Laterality property is |
Note that when a $lookup operation is performed on a SNOMED CT concept, servers SHALL return the full URI for the edition and version being used (see above) in the version
property. Other properties are at the discretion of the server and the client.
