VOIP and the Semantic Web

The availability of VOIP implementations based on standards (like Asterik or even Java-based implementations will enable the integration of VOIP wither other applications. A paper by Tomas Vitvar discusses the integration of VOIP with Semantic Web Services. Also an interesting application will be the integration of VOIP with the Semantic Desktop. Consider a scenario where a user gets a call from a project collaborator. As soon as the call arrives metadata is extracted from the call (either implicit metadata (e.g., the callee) or explicit metadata (e.g., the project the call is related to) and relevant project information is openend and presented automatically, which establishes the context of the VOIP call. Part of this scenario can be realized without any changes to the SIP - other parts (e.g, the transmission of explicit metadata) may require protocol enhancements.
