A flexible content repository to enable a peer‐to‐peer‐based wiki

Abstract

SUMMARYWikis-being major applications of the Web 2.0-are used for a large number of purposes, such as encyclopedias, project documentation, and coordination, both in open communities and in enterprises. At the application level, users are targeted as both consumers and producers of dynamic content. Yet, this kind of peer-to-peer (P2P) principle is not used at the technical level being still dominated by traditional client-server architectures. What lacks is a generic platform that combines the scalability of the P2P approach with, for example, a wiki's requirements for consistent content management in a highly concurrent environment. This paper presents a flexible content repository system that is intended to close the gap by using a hybrid P2P overlay to support scalable, fault-tolerant, consistent, and efficient data operations for the dynamic content of wikis. On the one hand, this paper introduces the generic, overall architecture of the content repository. On the other hand, it describes the major building blocks to enable P2P data management at the system's persistent storage layer, and how these may be used to implement a P2P-based wiki application: (i) a P2P back-end administrates a wiki's actual content resources. (ii) On top, P2P service groups act as indexing groups to implement a wiki's search index.

A State-of-the-Art Survey of Peer-to-Peer Networks: Research Directions, Applications and Challenges

“…1 shows a general architecture of a super-peer P2P network. As indicated by the following literature, there are ongoing efforts to maximize the advantages of P2P and that of other systems, leading to the development of more robust hybrid systems [12]- [14], [70]. The authors in [14] presented the development of a scalable, efficient and fault-tolerant hybrid of P2P network and wikis, an application of web 2.0 for use in content repositories.…”

Also, discussed were the key blocks that enable peer-to-peer data management at the system non-volatile storage layer for repositories.…”

Evaluation of intra‐group optimistic data replication in P2P groupware systems

“…P2P computing systems offer many advantages of decentralized distributed systems but suffer from availability and reliability. In order to increase availability and reliability, data replication techniques are considered commonplace in distributed computing systems [3,21,9,16].…”

“…P2P computing systems offer many advantages of decentralized distributed systems but suffer from availability and reliability. To increase availability and reliability, data replication techniques are considered commonplace in distributed computing systems [7][8][9][10].Replication can support complex computational processes in P2P systems, beyond simple file sharing, by increasing availability and reliability, and therefore, improve the perception of peers, yielding to fast response times and rich experience in such systems. Indeed, in P2P systems, users have often the perception of a highly unreliable system.…”
