  • Formatting was changed.


  • Completion of a major review and update with many new entries and updated definitions.
  • New entries have been added to the glossary from the Editorial Guide as well as from other documentation.
  • The format for entries has been standardized so that it begins with a single sentence definition:
    • The definition 
      • starts by specifying a general class
      • continues by specifying differentia that distinguish that term from the general class
      • does not include the defined term (though the definition of a term consisting of more than one word may include a words from the term when specifying the general class)
  • The formal definition is followed by the following sections:
    1. Notes - that provide a less formal description or explanation of the defined term
    2. Examples - that illustrate the defined term
    3. Alternatives - other words or abbreviations that may sometimes be used in place of the defined term
    4. Related Links - links to other glossary entries and/or related documentation
    5. Disambiguation - where there are other potentially confusing uses of the same term (or a similar term).
    6. Change Notices - where changes to SNOMED CT design has resulted in changes to definitions notes are added here. These notes may be removed in future versions of the glossary as they are specific to the transitional period of the changes noted.

Version Notes 2017-12-21

  1. To align with glossary practice in formal standard such as those published by

    , the glossary has been updated to use lowercase text for all terms, except where there is a specific reason to use upper case. Upper case characters continue to be used in product names, acronyms and terms that have a specific roles in the 
    tSNOMED CT Affiliate Licence Agreement
     and the 
    tArticles of Association


    As a result of this style change, the representation of the terms used in the glossary now matches expected usage of these terms in text. Therefore, if the glossary term appears in lower case, it should be used in lowercase. The only exceptions to this should be where the term is at the start of a sentence or in another situation (e.g. within a document or section title) where capitalization rules apply. During the first half of 2018 documents in the online SNOMED CT Document Library will be updated to follow this revised style convention.
