Modular Web Queries - From Rules to Stores.
Abstract
Even with all the progress in Semantic technology, accessing
Web data remains a challenging issue with new Web query languages and
approaches appearing regularly. Yet most of these languages, including W3C
approaches such as XQuery and SPARQL, do little to cope with the explosion
of the data size and schemata diversity and richness on the Web. In this
paper we propose a straightforward step toward the improvement of this
situation that is simple to realize and yet effective: Advanced module
systems that make partitioning of (a) the evaluation and (b) the
conceptual design of complex Web queries possible. They provide the query
programmer with a powerful, but easy to use high-level abstraction for
packaging, encapsulating, and reusing conceptually related parts (in our
case, rules) of a Web query. The proposed module system combines ease of
use thanks to a simple core concept, the partitioning of rules and their
consequences in flexible .stores., with ease of deployment thanks to a
reduction semantics. We focus on extending the rule-based Semantic Web
query language Xcerpt with such a module system though the same approach
can be applied to other (rule-based) languages as well.
