[apologies for multiple postings] Sedna XML DBMS is now available in source code under Apache License 2.0. You can find the source code of the currently developed version 0.3 from http://www.modis.ispras.ru/Development/sedna.htm. Please note that the code is unstable and we do not recommend to use it in production projects, for benchmarking Sedna, etc. Going free and open source with Sedna, we aim at getting more people involved in using Sedna, giving us feedback and contributing to the actual development of the code and documentation. Everybody's input is welcome! Features under development are: - Support for Linux - Document collections (that allows effective querying over a large collection of similar XML documents) - XQuery support extensions: user-defined XQuery functions - XML namespaces - Database Security - C API - Unicode - Regular Expression Library for XQuery - XQuery library for querying relational databases in SQL - ACID Transactions and Recovery Features: - Available for free in open source form - Native XML DBMS implemented from scratch in C/C++ and Scheme - Support for the W3C XQuery language (partial support for the latest working drafts of 29th October 2004) - Support for a declarative update language - Native XML data storage structures designed for efficient support for both queries and updates (no underlying relational or another DBMS). The XML data storage is based on descriptive schema (derived from data, also called DataGuide) - Efficient support for stand-alone XML documents with arbitrary structures and collections of XML documents with similar structures - Java API and Scheme API for application development - Open client/server protocol over sockets that allows implementing APIs for other programming languages - A data definition language that allows creating/droping XML documents and collections, printing the names of the documents stored in database, printing the descriptive schema of XML documents. - Administration via easy-to-use command line utilities - Supplied with extensive documentation including Quick Start Please, notice that using the client/server protocol you can easily implement APIs for your favorite programming language.
