Excerpt

Purpose

The 

Concept

...

t705109006 Code to expression type reference set
 is designed to enable associations between codes in another code system 
Gloss
t(other-codes)
t:other-codes
 and 
Gloss
tSNOMED CT concepts
, where the following constraints apply:

  1. Some of the 
    Gloss
    tother-codes
    t:other-codes
     cannot be mapped to an individual SNOMED CT 
    Gloss
    tconcept
    .
  2. Licensing conditions (or other considerations) prevent addition of new SNOMED CT concepts to represent the same meaning as the 
    Gloss
    tother-codes
    t:other-codes
    .
  3. The 
    Gloss
    tother-codes
    t:other-codes
     can be logically defined using the 
    Gloss
    tSNOMED concept model
     to represent the same meaning 
    Gloss
    t(sufficiently defined)
     or a similar though less specific meaning 
    Gloss
    t(primitive)
    .
  4. Other requirements similar for those applicable to mapping may also apply including:
    1. An indication of the degree of correlation between the  
      Gloss
      tother-code
      t:other-codes
       and the SNOMED CT expression.
    2. An indication of whether the 
      Gloss
      tother-code
      t:other-codes
       was created before any single concept representation of that meaning in SNOMED CT or whether the single concept representation in SNOMED CT predated the creation of the association.

Data Structure

The general approach to the above requirements is to associate each of the 

Gloss
tother-codes
t:other-codes
 with a representation of the same logic based definition as would have been applied to a SNOMED CT concept with that meaning. However, since the  
Gloss
tother-code
t:other-codes
 are not identified by an  
Specref
RefTypedata type
tSCTID
, the logical definition cannot be represented using  
Gloss
tdefining relationships
. There are two potential approaches to this, one would be to use a general purpose description logic language (e.g.  
Gloss
tOWL
) and the other is to use a 
Gloss
tSNOMED CT expression
 to represent each definition. The 
Concept
ShowPartsterm
t705109006 Code to expression type reference set
 is designed to support the expression-based approach.
