MIX: A Meta-data Indexing System for XML
نویسندگان
چکیده
We present a system for efficient meta-data indexed querying of XML documents. Given the diversity of the information available in XML, it is very useful to annotate XML data with a wide variety of meta-data, such as quality and security assessments. We address the meta-data indexing problem of efficiently identifying the XML elements along a location step in an XPath query, that satisfy meta-data range constraints. Our system, named MIX, incorporates query processing on all XPath axes suitably enhanced with metadata features offering not only query answering but also dynamic maintenance of meta-data levels for XML documents.

متن کاملXML Query Routing in Structured P2P Systems
This paper addresses the problem of data placement, indexing, and querying large XML data repositories distributed over an existing P2P service infrastructure. Our architecture scales gracefully to the network and data sizes, is fully distributed, fault tolerant and selforganizing, and handles complex queries efficiently, even those queries that use full-text search. Our framework for indexing ...
