Logical Model: II - Detailed Descriptions

Active as of 2023-10-03

Definitions for the II logical model.

Guidance on how to interpret the contents of this table can be found here

0. II
Definition

An identifier that uniquely identifies a thing or object. Examples are object identifier for HL7 RIM objects, medical record number, order id, service catalog item id, Vehicle Identification Number (VIN), etc. Instance identifiers are defined based on ISO object identifiers.

Control1..*
XML FormatIn the XML format, this property has the namespace urn:hl7-org:v3.
2. II.assigningAuthorityName
Definition

A human readable name or mnemonic for the assigning authority. The Assigning Authority Name has no computational value. The purpose of a Assigning Authority Name is to assist an unaided human interpreter of an II value to interpret the authority. Note: no automated processing must depend on the assigning authority name to be present in any form.

4. II.displayable
Definition

Specifies if the identifier is intended for human display and data entry (displayable = true) as opposed to pure machine interoperation (displayable = false).

6. II.root
Definition

A unique identifier that guarantees the global uniqueness of the instance identifier. The root alone may be the entire instance identifier.
