Context Policies
Context policy items can include the following domain-based rules:
Access control rules that establish the access control against specific participant, object type, life cycle state, and domain combinations.
For example, there can be an access control rule for objects with the wt.doc.WTDocument object type in the /Default domain that gives read permission to the Engineers system group.
Indexing rules that define which collections an object is included in when the object of a specified object type and domain combination moves to a specific life cycle state. Collections are used to create indexing lists which help improve performance when searching for objects.
Notification rules that define which participants get notified when a specified event occurs for an object type and domain combination.
Contexts provide a means for controlling access to the contained information. In application contexts, access is controlled through context team membership, policy rules, and ad hoc rules. Context contents can be restricted so that access is limited to the members of a context team, or so that the context information can be made more broadly available to the enterprise through policies that grant additional participants (such as users, groups, or organizations) access to specific object types.
The policies that are in effect in a context are determined by the policies set in the domains that are in the current context, as well as those set in the parent domains. For details, see Administering Domains and Policies.
