Peer-to-Peer Schema Mapping Composition Based on XSLT Template Unfolding
Zheng Zhao · Jisuanji gongcheng · 2009
Aiming at the time-consuming problem of multiple reformulations when bypassing left peers in peer data management system, a peer schema mapping composition method is proposed based on XSLT template unfolding.By matching and unfolding template contents consecutively, the method processes two mappings expressed in an XSLT subset with the style of matching templates, and forms a composed mapping equivalent to multiple mappings.When neighboring peers on mapping path depart together, agent peer no longer reformulates multiple times, but uses composed peer to bypass directly.Simulation results show that the composition method can produce equivalent mappings correctly.By passing time shortens significantly and network topology becomes robust.
