• 5.2.1.3.1 - Bind Models Sept. 6, 2010 Bind models to data types and value sets An artifact description associates a resource with normative definitions of value specifiers. A value specifier includes a collection of value sets. A value set is defined in terms of its structure and semantics. A property-value pair construct binds an artifact description to the semantics of a value set within a given execution context.
• 5.2.1.3.2 - Constrain Sept. 6, 2010 A policy represents some constraint or condition on the use, deployment or description of a resource as defined by a participant or, more generally, a stakeholder. A contract is a constraint that has the agreement of the constrained participants. A policy constraint is a measurable proposition that characterizes the constraint that the policy is about. A permission constraint governs the ability of a participant or other actor to perform an action or enter some specified state. An obligation constraint governs the requirement that a participant must perform some action or maintain some state.
• 5.2.1.3.3 - Extend Sept. 6, 2010 There were more requests for various types of extensibility than any other category of request other than improvements to tool interfaces. caBIG users and other stakeholders articulated a compelling business need to readily extend models, terminologies, and data elements in a variety of ways A policy represents some constraint or condition on the use, deployment or description of a resource as defined by a participant or, more generally, a stakeholder. A permission constraint governs the ability of a participant or other actor to perform an action or enter some specified state. The ability to extend a service specification, including any associated model artifact, is subject to the permission policies embodied in the contract between the participants.
• 5.2.1.3.4 - Model Sept. 6, 2010 Create, destroy, edit, and maintain models.
• 5.2.1.3.5 - Semantic Annotation Sept. 6, 2010 In a diverse information environment, semantics must be used to clearly indicate the meaning of data. This requirement is expected to be addressed by the Semantic Infrastructure, although there will be a touchpoint between the caGrid 2.0 and the Semantic Infrastructure to annotate data with semantics.
