Workshop theme and goals
-------------------------
The aim of the workshop is to bring together researchers that deal with the problem of envisaging intelligent mechanisms and efficient techniques that provide novel approaches of modeling, indexing, searching, retrieving and engineering methods that are already applied in Peer to Peer and Service Oriented Hypermedia environments.
The most popular instance of hypertext is by far the Web, which lacks many of the hypertext properties. The integration of hypermedia techniques into the WWW has seen considerable research attempts, though it has not known wide public acceptance yet. One key drawback that has kept this integration from moving forward is the dominating centralized model. Most systems have been characterized by local storage of hypermedia structures in order to face scalability issues. However, these systems lack the potentials of serendipity and service orientation. In contrast, over the past few years, several other promising non-centralized, open and service driven solutions have been promoted. In previous HyperText Conferences, the idea of multiple open services has been proposed in order to rethink the way in which services are provided to clients with goal to split up services into generalized independent components - services. An instantiation of such an attempt was the proposed process for creating Web Services and mapping functions of hypermedia services to operations of Web Services and vice versa.
In parallel trail, the peer-to-peer paradigm which is characterised by equal capability of participating nodes and decentralisation of control can be used to support a distributed open hypermedia system for collaboration. The combination of P2P and hypermedia has seen some promising speculation and development in several recent HT Conferences (HT
2004 P2P section, HT 2003 Storm Hypermedia system, HT 2002 introduction for the notion of P2P Hypertext). Service Oriented Environments and Peer to Peer technology are categorized among the newest members of the Web engineering area and they have already attracted both scientific community and vendor attention. Hypermedia approaches have been already presented that integrate these technologies.
In this workshop, the key concept and aim is to give the opportunity to researchers to present their original work on issues pertaining to the interplay of Service oriented computing, architectures for Peer-to-Peer systems and efficient techniques for modeling, retrieval and organization of XML data.
