A User identity subject identifies a user that exists in the real world. Users can have different logon names for different applications. A site-defined suffix of a subject identifier item differentiates user logon names for different applications.
User subjects have the following attributes:
|Security||Requires authentication to set subject|
|Mapping Agent Coupon Value||-2|
User-linked applications should be configurable to use the appropriate suffix (or suffixes) when getting or setting context data. Any application can log a user off of all the user-linked applications. Applications log users off by setting the user subject to empty.
User subjects have the following standard context data items. A User Linked application should set the value for at least one of the items listed in the following table:
|User Subject Identifier Item Name||Meaning||Data Type||Semantic Constraints on Values||Case Sensitivity|
|User.Id.Logon.Suffix||User's logon name||ST||None||Value is case sensitive.
For example, “gsmith” and “Gsmith” are two different logon ID values
An application can optionally set values for the corroborating items listed in the following table:
|User Subject Corroborating Item Name||Meaning||Data Type||Semantic Constraints on Values||Case Sensitivity|
|User.Co.Name||User's name (No meaning for HL7)||XPN||None||No|
Examples of User Subject Items are listed in the following table:
|Example Item Names||Example Item Values|
