Class: UniqueIdentifierString
Documentation: A unique identifier string is a character string which identifies an object in a globally unique and timeless manner. The allowable formats and values and procedures of this data type are strictly controlled by HL7. At this time, user-assigned identifiers may be certain character representations of ISO Object Identifiers (OID) and DCE Universally Unique Identifiers (UUID). HL7 also reserves the right to assign other forms of UIDs, such as mnemonic identifiers for code systems.
The sole purpose of the UID is to be a globally and timelessly unique identifier. The form of the UID, whether it is an OID, an UUID or any other form is entirely irrelevant. As far as HL7 is concerned, the only thing one can do with a UID is denote to the object for which it stands. Comparison of UIDs is literal, i.e. if two UIDs are literally identical, they are assumed to denote to the same object. If two UIDs are not literally identical they may not denote to the same object.
