Semantic Policy Enforcement and Reconciliation for Information Exchange in XMPP
نویسندگان
چکیده
Extensible Messaging and Presence Protocol (XMPP) is a popular open-standard protocol for instant messaging (IM) widely used in military and commercial applications. In military contexts, as in commercial settings, it is often necessary to regulate who may communicate with whom and how. The distributed nature of XMPP makes centralized information exchange policy enforcement impossible, however. We report on a technology we have developed, called PolVISor, in which we express information exchange policies in a natural language formalism (SBVR SE), automatically translate these policies into an executable rule language (BaseVISor rule language) and enforce and reconcile disparate policies among XMPP servers, each with its own policies, using semantic technologies.
