At level 1, the terminology server will accept CTU expressions matching the following pattern:

[[<<  71388002 |Procedure| @procedure]]:
    [[0..1]]  408730004 |Procedure context|  = [[+id(<<  288532009 |Context values for actions| ))@context]],
    [[0..1]]  408731000 |Temporal context|  = [[+id(<<  410510008 |Temporal context value| )@time]],
    [[0..1]]  408732007 |Subject relationship context|  = [[+id(<<  125676002 |Person| )@person]] 

This pattern allows attributes applicable to the  29125009 | Procedure with explicit context (situation)| domain to be used to add contextual information to procedures.

Important Notes

The terminology server will only accept expressions complying to this pattern if the focus concept of the CTU expression has the following characteristics:

  • The focus concept
    • is the concept 71388002 |Procedure| or a subtype hereof
  • For each expression, only one instance of each attribute is accepted
  • The value of the attribute must be within the allowed range of the attribute as specified by the MRCM

The generated classifiable form must be based on the following expression with 29125009 | Procedure with explicit context (situation)|  as the focus concept and the following default attributes and values, unless otherwise specified by the CTU. The value of the Associated procedure attribute will be replaced by the focus concept of the CF expression.
