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 |
