HL7 Datatypes 簡述

 

EncapsulatedData (ED): Data that is primarily intended for human interpretation or for further machine processing outside the scope of HL7.

ConceptDescriptor (CD):A reference to a concept defined in a code system

CodedSimpleValue (CS):Coded data in its simplest form, where only the code is not predetermined. The code system and code system version are fixed by the context in which CS value occurs. CS is used for coded attributes that have a single HL7-defined value set.

Interval (IVL):A set of consecutive values of an ordered base data type.

Boolean (BL): A binary value for use in boolean logic. A BL value can be either true or false, or, as any other value, MAY be NULL.

CNE(Code without Exception):取代CE這個Datatype，不可extent原本的coding

CWE(Code With Exception)：也是取代CE這個Datatype，可以extend原本的coding
