Tue, 07 Feb 2012 23:47:00 +0100

Dear all,
three months have passed, and we are now proud to release BaseX 7.1, a.k.a. the XMLPrague 2012 Edition! These are some of the new exciting features (a full list is attached below):

GUI: the management of your databases, documents & binary files and index structure has got easier than ever before!
JSON: import, query and export your JSON data via XQuery, REST, or on command line!
Incremental Indexing: update your text and attributes index in realtime!
Enhanced Path Statistics: retrieve distinct values of location paths in constant time!
New XQuery functions to simplify database, full-text, index, and repository access
New XQuery 3.0 Features: support for EQNames, namespace constructors, etc.
Revised Command-Line API: process multiple inputs or commands in one run
Document Index: improved update performance

BaseX is a light-weight, high-performance and scalable XML Database and XPath/XQuery Processor, including full support for the W3C Update and Full Text extensions. An interactive and user-friendly GUI frontend gives you great insight into your XML documents and collections. BaseX is platform independent, fully Open Source (BSD-licensed) and backed by commercial services. And what's best: it is easy to use and runs straight out of the box! We hope you have fun with our latest release, and we're looking forward to your feedback, Christian

BaseX 7.0: TEI Edition

Fri, 14 Oct 2011 16:53:00 +0200

Thanks everyone for your support! We are more than excited to announce BaseX 7.0 (a.k.a. the TEI Edition), the best version we have ever released! It includes an impressive bunch of new features:

STORAGE: Files of any data type can now be stored in BaseX in their raw representation. This means that BaseX can now be used as a full-fledged storage system. Next, millions of documents can now be added faster than ever before.
APIs: We have rewritten our HTTP services: Our REST implementation has been integrated much more tightly in the core system. It can be used to query XML data, retrieve binary resources, and send database commands. A new WebDAV API provides access to the database via your file system, oXygen and various other clients. The classical clients (available for 10 different programming languages) have been extended and sped up.
XQUERY: Numerous modules have been added to process all kinds of data formats via XQuery: JSON documents can be parsed and serialized, SQL databases can be queried, XSLT cryptographics functions are available to encrypt data and use XML signatures. Our database module has been extended to facilitate the storage and modification of database resources.
FULL-TEXT: We now offer tokenization and stemming support for 21 different natural languages, including Japanese (thanks to Toshio HIRAI!). Next, we have further optimized the internals of our retrieval features of BaseX.

We hope you have fun with our latest release, and we're looking forward to your feedback! Christian
