- Resource lists (auid = resource-lists). A resource lists application is any application that needs access to a list of resources, identified by a URI, to which operations, such as free trials without subscriptions, can be applied.
- Presence rules (auid = pres-rules, org.openmobilealliance.pres-rules). A Presence Rules application is an application which uses authorization policies, also known as authorization rules, to specify what presence information can be given to which watchers, and when.
- RLS services (auid = rls-services). A Resource List Server (RLS) services application is Session Initiation Protocol (SIP) a
- XML manipulation (auid = XML-manipulation). XML-manipulation application usage defines how XCAP is used to manipulate the contents of XML based presence documents.
