Mapping Maintenance in XML P2P Databases [chapter]

Dario Colazzo, Carlo Sartiani
2005 Lecture Notes in Computer Science  
This paper describes a novel technique for maintaining mappings in XML p2p databases, based on a semantic notion of mapping correctness.  ...  A main problem in mapping-based systems is the maintenance of schema mappings, and, in particular, the detection of corrupted mappings.  ...  In particular, we plan, in the near future, to implement this technique in a centralized, logical p2p system, so to verify its applicability in a background maintenance activity.  ...

Peer-to-Peer Semantic Integration of XML and RDF Data Sources [chapter]

Isabel F. Cruz, Huiyong Xiao, Feihong Hsu
2005 Lecture Notes in Computer Science  
In this paper, we propose a P2P data management framework named PEPSINT that semantically integrates heterogeneous XML and RDF data sources, using a hybrid architecture and a global-as-view approach.  ...  Peer-to-Peer (P2P) data management systems combine traditional schema-based integration techniques with the P2P infrastructure.  ...  We discuss the construction of the architecture, maintenance of mappings, and query processing in PEPSINT.  ...

Peer-to-peer management of XML data

Georgia Koloniari, Evaggelia Pitoura
2005 SIGMOD record  
The widespread use of XML as a standard for representing and exchanging data in the Internet suggests using XML for describing data shared in a p2p system.  ...  In this paper, we focus on data management issues for processing XML data in a p2p setting, namely indexing, replication, clustering and query routing and processing.  ...  p2p management of XML Structured P2P Unstructured P2P Non P2P Mapping of paths onto the Use of space efficient routing Pure P2P  ...

Distributed Search and Pattern Matching [chapter]

Reaz Ahmed, Raouf Boutaba
2009 Handbook of Peer-to-Peer Networking  
Representative search techniques from three application domains, namely, P2P content sharing, service discovery and distributed XML databases, are considered.  ...  Peer-to-peer (P2P) technology has triggered a wide range of distributed applications including file-sharing, distributed XML databases, distributed computing, server-less web publishing and networked resource  ...  Distributed XML Databases Distributed XML databases on P2P systems, or P2P Databases Systems (PDBS) in short, have been investigated, more recently, following the success of P2P content sharing.  ...

Query routing and processing in schema-based P2P systems

M. Karnstedt, K. Hose, K.-U. Sattler
2004 Proceedings. 15th International Workshop on Database and Expert Systems Applications, 2004.  
Recently, the peer-to-peer (P2P) paradigm has emerged, mainly by file sharing systems such as Napster and Gnutella and in terms of scalable distributed data structures.  ...  However, several design and technical challenges arise in building scalable P2Pbased integration systems. In this paper, we address one of them: the problem of distributed query processing.  ...  The decentralized nature of P2P systems makes it difficult to directly use well-known processing strategies from distributed database systems.  ...
