U-P2P: a peer-to-peer system for description and discovery of resource-sharing communities

Abstract

Abstract--A simple method is proposed for peer-to-peer description and discovery of resource-sharing communities as well as the resources themselves. An XML Schema document describes a shared resource. By applying transformations, specified in XSL, the schema is used to generate an application with the ability to publish and search for the defined object. Meta-data is indexed and searchable allowing complex objects to be discovered. We propose to solve the problem of discovery for resource-sharing communities by treating a community as a shared resource. An XML Schema description of resourcesharing communities is used to generate a P2P system for community discovery.

Peer-to-peer data integration with distributed bridges

“…U-P2P [13,6] is an open source framework for sharing data described in XML over any supported peer-to-peer network. At its core, the three shared components in U-P2P are resources, communities and attachments.…”

“…Using the peerto-peer approach, we propose the use of usercontributed mappings or "bridges" that can be published and exchanged over a network of peers. Universal Peer-to-Peer (U-P2P) [13,6] is a framework that allows peer-to-peer sharing of documents enclosed in a user-defined and Copyright c 2006 Neal Arthorne and Babak Esfandiari.

Collaborative knowledge construction in a peer-to-peer file sharing network

“…We base this work on an existing prototype file-sharing application called U-P2P, first presented in [3], which allows users to share structured XML documents. Users may contribute new documents of a given schema, but also define new document types, or concepts, in the form of XML schemas and customized presentation templates.…”

“…We present briefly our prototype file-sharing system U-P2P [3], in its existing form prior to this thesis.…”

“…3 Actor which implement a client for the protocol, and can be automatically used by U-P2P. We note that a proof-of-concept study for this representation of protocols was presented in [3], but in the most recent versions of U-P2P, this feature has been abandoned for simplicity's sake: all implemented communities are required to use the Gnutella protocol, which is now hard-coded into the application.…”
