+
===As Used In Higgins===
+
* Most [[Digital Subject]]s have one [[SubjectId]] [[Identity Attribute]]
+
* Some of these [[Identity Attribute]]s may be [[Relation]]s that  are references to other [[Digital Subject]]s in the same or different [[Context]]s
+
* Relationship to an [[Entity]]: Although any given [[Digital Subject]] is relevant to, and exists within a given [[Context]], a single [[Entity]] may be represented as one (or more) [[Digital Subject]](s) in one [[Context]] and yet other [[Digital Subject]]s in another [[Context]]s. By linking or "federating" these disparate [[Digital Subject]]s one can gain a more unified view of a given [[Entity]]. [[Context]]s representing different systems, organizations and entire enterprises with widely varying storage and trust models are handled using this [[Digital Subject]] linking approach. For example the [[Entity]] "Bob Smith" could be represented as two [[Digital Subject|Digital Subjects]]; the first having "bsmith" as an identifier and the second having "bob" as an identifier. These two [[Digital Subject]]s may be in the same or in different [[Context]]s.
+
* [[Context]]s can be nested (e.g. enterprises have sub-organizations, and there are systems within an enterprise/org, etc.) or related through other means (employment/HR system vs. customer system where same person is a customer and an employee). Thus linking the [[Digital Subject]]s relevant to those contexts provides an overall view of a [[Digital Subject]] (or at least a partial "overall" view to those [[Context]]s).
+
* The information contained in a [[Digital Subject]] is not necessarily a pure subset of the union of all of the information contained in all of the [[Digital Subject]]s of an [[Entity]] taken together. There is no consistency constraint imposed between the [[Digital Subject]]s of an [[Entity]]. For example, a person could claim that their name was Joe in one [[Digital Subject]] and JoAnn in another.
