Knowledge Architect/Reference/Glossary/E


An information security process where information is encrypted and can only be accessed by owners of the corresponding decryption key. All communication and long term persistence of private content, profiles, and resources should be encrypted, and keys managed the accordingly. See also AuthorizationAuthenticationEntitlement.

See Organization.

A resourcerelation type that defines responsibility, accountability, access rights, privileges, policies, and tracking between associated resources. The process of securingresources by constraining access of subject resources over object resources, in real-time, on every access, with unlimitedgranularity, to ensure that: users are given access only to all resources that they are entitled to, for any given context. Entitlement is expressed, modeled, and managed as a resource relation type, that defines access rights, roles, and policies between resources. Entitlement is at the root of distributedvirtualprofileapplications, because of the important associated security considerations. Entitlement is a fundamental information and knowledge sharing enabler, combining EncryptionAuthorizationAuthentication with resource management to offer secure information sharing and access. Run-time entitlement is provided and enforced by the DNAOS Reference Monitor.

As knowledge naturally maps to resources, as consequently resources are everything, and as tradition (e.g. databases, UML) and logic typically differentiate entities and relations, entities are resources that are not relations (e.g. that do not also define relations between other resources). Unfortunately, [ISO TC97/SC5/WG3 TR 9007 (1982)] defines entity as "any concrete or abstract thing of interest, including associations between things.", breaking with common usage, tradition, and logic, especially as beings, for example, are not typically referred to as things, but commonly as resources. Entity is also sometime used as a synonym for party or owner resources, which we will also avoid, to try to limit confusion, especially as party and owner already describes those resources.

A sequence of values.

Calculating the value of resources.

The assessment of resources against defined criteria.

Events are actionresources that signal an activityphase transition. Event complexity can vary considerably, from simple signals to rich notification messages.
