Zorba

Zorba 2 is an extensive rewrite and re-architectural work, with improved stability, complete functionality, and max conformance level. It supports W3C specs (XQuery 1.0 with XMLSchema validation, XQuery 3.0 June 2011 draft with try-catch, groupby, outerjoins, XQuery Update 1.0, XQuery Full Text 1.0, and XSLT 1.0), extension specs (XQuery Data Definition (collections, indexes and integrity constraints) and XQuery Scripting Extension), and an extensive set of modules (process, system, HTTP, data cleaning, data conversion (JSON, CSV, HTML), excel, cryptography, geo, image, oauth, and email).

Various bugfixes.

Besides bugfixes and performance improvements, this release comes with an extended function library and support for the XQuery 1.1 switch expression. You can find examples for the new features that are ready to execute in the live demo. Moreover, the tutorial “Atom Processing with Zorba” shows how easy it is to develop a tiny mashup entirely in XQuery with Zorba and the EXPath HTTP client.

This release contains mostly bugfixes and major performance improvements. It also contains a preliminary implementation of higher-order functions as specified in XQuery 1.1.

The following specifications are implemented in this version: XQuery 1.0 (with schema validation) (99.5%W3C tests success rate), XQuery Update (97.2%), XQueryX (98.5% success rate for XQuery 1.0 and 96.6% for XQuery Update), many XQuery 1.1 features (including try-catch, windowing and general FLWOR expressions), and XQuery Scripting Extension. This release includes support for data definition and manipulation (collections, indexes, and integrity constraints). It also extends the standard XQuery capabilities with a rich and extensible function library, including xqDoc, REST, JSON, CSV, Excel functions, email, introspection, file manipulation, and mathematical computations. Zorba 1.0 includes lots of bug fixes and performance improvements as well.
