   or a defined collection of data items in an

   information model.  The clinical meaning represented by of an instance of a data item with a meaning binding is determined by applying the meaning bindingto the value or set of values in that instance. The

   that can be replaced by concepts entered or stored in a particular context.

Example

• An application that manages surgical procedure requests could identify requested procedures using concepts that are subtypes of 

  Concept
  t 387713003 Surgical procedure

  . In this case, the data item in which that concept is recorded should have a meaning binding that explicitly indicates that this is a request (e.g. the for that procedure. The expression template below ). When this meaning binding is applied this data item is interpreted as a subtype of

   and not as a completed procedurerepresents this meaning binding. It indicates that the procedure selected should replace the "@procedure"

  , resulting in an 

  Gloss
  t expression

   that means procedure has been requested, rather than suggesting incorrectly, that it has been done.

/* Expression Template */
