REFORM

A System for Rewriting XML Nested Queries Using Nested Views


Welcome to the REFORM Website!
REFORM was created as a a system for rewriting XML nested queries using XML nested views. It takes an input XQuery expression and a set of XQuery views and it returns an XQuery expression equivalent to the original one, but formulated in terms of the views output schemas. When it cannot find such a rewriting, it fails with an error message.
More details are available on the overview page.

Latest News NEW
  • May 2007. The capacity to input user defined rewriting rules has been added to the rewriting engine and can be tested in Usecase 3 of our demo.

Older News
  • February 2006. The language of the input queries was extended to NEXT+ which covers most of XQuery, including function calls. Check queries q05 and q06 in usecase2 of the demo.
  • December 2005. REFORM webdemo is now available!
Coming Soon
At present, we are working on new features that will be part of the future release:
  • allow for the top query node to be an arbitrary expression (for instance an Element Construction)
  • add the option of choosing between ordered and unordered semantics
