CCOW View Identity Subjects

View Identity Subjects

The View Identity subject represents a particular view, screen or presentation for each application in a context sharing setting. The View subject collectively renders a coordinated series of data to support a user's task. Views are site specific and are defined to accommodate specific user roles, a specific user, and specific groups of users. The data values for View subjects are an alphanumeric strings and items.

View subjects have the following attributes:

Subject Label “View”
Subject type Identity
Synchronization Temporary
Security None
Subject Dependencies None
Mapping Agent Coupon Value -10

A View mapping agent configures site-specific mappings of View data values to accommodate different applications in the context system. A site-defined suffix is used with the name of the subject's identifier items. A View-Link-enabled application should be configurable to use site-specific suffixes to set and get view context data.

All View-Link-enabled applications are required to support the pre-defined View subject values “Stay” and “Home”. “Stay” means an application should not change its current view or when not possible to remain in the current view should present a view close to the current view. “Home” means that the application should display its highest-level view or its default view. The View mapping agent can be used to set the View subject's value for an application to one of the pre-defined values in the previous table or set it to empty. This allows an application to be unconstrained in its response to a view context change by another application. An application should not set the View context when it is a participant in a context change transaction instigated by another application.

View subjects have the following standard context data items listed in the following table:

View Subject Identifier Item Name Meaning Data Type Semantic Constraints on Values Case Sensitivity
View.Id.View.Suffix The application view to be presented ST None No
