Abstract	The Internet is currently being designed and used in a way that is strongly influenced by inter-personal communications and content-based services. Content Networks, having presence and audiovisual metadata descriptions as central concepts, can play an important role in the provision of these services. Existing standards from the ISO/IEC MPEG (MPEG-7,-21) and IETF (PIDF, RPID) provide the technologies for these elementary features. This paper contributes to the deployment of Content Networks by proposing a layered architecture where the IMS Multimedia Subsystem and P2P-based midlleware tackle the problem of terminal, networks heterogeneity and the integration of different presence and metadata tools. The P2P-based middleware is used to construct autonomously self-organized, context and interest based communities by providing overlay infrastructures for the interconnection of different Content Networks components. The results obtained from implementing this architecture using Open IMS Core and Scribe open platforms show that the proposed architecture can be used for the creation and deployment of services on Content Networks.
