User Identity Subjects

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:

Subject Label	“User”
Subject type	Identity
Synchronization	Constant
Security	Requires authentication to set subject
Subject Dependencies	None
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
User.Id.Logon.LEADTOOLS_Demo_Workstation	g_smith
User.Id.Logon.Visage	gsmith
User.Id.Logon.CareView	gs1229
User.Co.Name	Gabi Smith
