The [http://www.identitygang.org/DigitalSubject IdentityGang.org definition] of [[Digital Subject]] is:

+
[[Category:Higgins Obsolete Pages]]
:An ''Entity'' represented or existing in the digital realm which is being described or dealt with.
+
 
+
Their relationship to [[Attributes]] is mentioned in the IdentityGang definition of Identity Attribute :
+
 
+
:A property of a ''Digital Subject'' that may have zero or more values.

In Higgins:
+
 
+
* 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 [[Digital Subject]] in one [[Context]] and as another [[Digital Subject]] in another [[Context]] (and perhaps still others). By linking or "federating" these disparate [[Digital Subject|Digital Subjects]] one can gain a more unified view of a given [[Entity]]. [[Context|Contexts]] 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|Digital Subjects]] may be in the same or in different [[Contexts]].
+
* In addition to simple scalar values the [[Attributes]] contained in a [[Digital Subject]] may contain a reference to other [[Digital Subject|Digital Subjects]] in the same or different [[Contexts]]
+
* [[Contexts]] 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|Digital Subjects]] relevant to those contexts provides an overall view of a [[Digital Subject]] (or at least a partial "overall" view to those [[Contexts]]).
+
 
+
Subclasses of Digital Subject:
+
* A "Subject Group" is a kind of [[Digital Subject]] that is an aggregate "group" of other [[Digital Subject|Digital Subjects]]: A [[Digital Subject]] representing a group, e.g. the US Tennis Team, is related to the [[Digital Subject|Digital Subjects]] of its constituent players.
+
 
+
The following paragraph has been contributed, but needs further discussion to clarify:
+
* Given that an [[Entity]] may have multiple [[Digital Subject|Digital Subjects]], the relationships between these may need to be maintained. The relationship can be maintained in a single place for a set of [[Contexts]] (e.g, enterprise id with system accounts wrt operating systems); for others, they may still be treated [[Digital Subject|Digital Subjects]] and thus consider [[Digital Subject|Digital Subjects]] to be federated - both within and across contexts/enterprises/orgs.
+
 
+
Note:
+
* 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|Digital Subjects]] of an [[Entity]] taken together. There is no consistency constraint imposed between the [[Digital Subject|Digital Subjects]] of an [[Entity]]. For example, a person could claim that their name was Joe in one [[Digital Subject]] and JoAnn in another.
