BaseX is a light-weight, high-performance and scalable XML Database and an XQuery 3.1 Processor with full support for the W3C Update and Full-Text extensions. It allows you to store, query and process large corpora of textual (XML, HTML, JSON, CSV, others) and binary data. The GUI provides an XQuery editor for writing complex applications and provides various visualizations to interactively explore data. RESTXQ enables Web Application development in XQuery. BaseX is platform-independent and distributed under the free BSD License (find more in Wikipedia).
This is the documentation for BaseX 9.7. The newest and upcoming features are Template:Mark.
If you have questions, or if you want to get into direct contact with the developer team and users of BaseX, please write to our basex-talk mailing list. Many questions are being discussed at StackOverflow; planned features are listed in our GitHub repository.
The getting started section gives you a quick introduction to BaseX. We suggest that you start with the Graphical User Interface as this is the easiest way to access your XML data, and to get an idea of how XQuery and BaseX works.
More information on using the wide range of XQuery functions and performing XPath and XQuery requests with BaseX can be found in our XQuery Portal.
The developer section provides useful information for developers. Here you can find information on our supported client APIs and HTTP services, and we present different ways how you can integrate BaseX into your project.
Information for advanced users can be found in our advanced user's guide, which contains details on the BaseX storage, the Client/Server architecture, and some querying features.
