The Namespace Hierarchy

SNOMED CT core release files include metadata concepts that represent each of the allocated namespace-identifiers.

A namespace concept has the following characteristics:

  • It is a subtype child of 370136006 |Namespace concept|

  • The fully specified name of the concept has the term

    • Extension Namespace {nnnnnnn}(namespace concept)

  • A synonym associated with each concept has the term

    • Extension Namespace {nnnnnnn}

  • Where appropriate further synonyms may be included to identify the nature of the responsible organization.

In the terms shown above {nnnnnnn} is the seven digit namespace identifier of the responsible organization.
