Redland is a library that provides a high-level interface for RDF allowing the RDF graph to be parsed from XML, stored, queried and manipulated. Redland implements each of the RDF concepts in its own class via an object based API, reflected into the other language APIs - Perl, Python, Tcl, Java and Ruby. Some of the classes providing the parsers, storage mechanisms and other elements are built as modules that can be added or removed as required.
This library is mature and has been used in large systems. See the todo list or the website version for an up-to-date copy, and the FAQS for more information. Changes can be found in the NEWS file or more detailed changes in the ChangeLog.
Redland provides:
The packaged sources are available from http://www.redland.opensource.ac.uk/dist/source/ (master site) and also from the SourceForge site. There are nightly snapshots of the development version which is can also be browsed via CVSweb.
This library is free software / open source software released under the LGPL or MPL licenses. See LICENSE.html for full details.
See INSTALL.html for general installation and configuration information and the language specific documents for installing the interfaces in Perl, Python, Tcl, Java or Ruby.
Further documentation is available in the documents area including the API document.
