A schema-based P2P network to enable publish-subscribe for multimedia content in open hypermedia systems
Tiropanis, Thanassis and Kanellopoulos, Dimitris (2008) A schema-based P2P network to enable publish-subscribe for multimedia content in open hypermedia systems. International Journal of Web Engineering and Technology, 4, (1), 21-43. (doi:10.1504/IJWET.2008.016103).
Open Hypermedia Systems (OHS) aim to provide efficient dissemination, adaptation and integration of hyperlinked multimedia resources. Content available in Peer-to-Peer (P2P) networks could add significant value to OHS provided that challenges for efficient discovery and prompt delivery of rich and up-to-date content are successfully addressed. This paper proposes an architecture that enables the operation of OHS over a P2P overlay network of OHS servers based on semantic annotation of (a) peer OHS servers and of (b) multimedia resources that can be obtained through the link services of the OHS. The architecture provides efficient resource discovery. Semantic query-based subscriptions over this P2P network can enable access to up-to-date content, while caching at certain peers enables prompt delivery of multimedia content. Advanced query resolution techniques are employed to match different parts of subscription queries (subqueries). These subscriptions can be shared among different interested peers, thus increasing the efficiency of multimedia content dissemination.
