Redland RDF Application Framework

Dave Beckett

Overview

Redland is a library that provides a high-level interface for the Resource Description Framework (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 language APIs, currently C#, Java, Perl, PHP, Python, Ruby and Tcl. Several classes providing functionality such as for parsers, storage are built as modules that can be loaded at compile or run-time as required.

This is a mature and stable RDF library developed since 2000 used in multiple projects. See the FAQS for general information and the Redland issue tracker for known bugs and issues. A summary of the changes can be found in the NEWS file, detailed API changes in the release notes and file-by-file changes in the Subversion ChangeLog.

Redland provides:

A modular, object based library written in C
APIs for manipulating the RDF graph and parts - Statements, Resources and Literals
Language Bindings in C#, Java, Perl, PHP, Python, Ruby and Tcl via the Redland Bindings package.
Support for multiple syntaxes for reading and writing RDF with Parsers and Serializers for RDF/XML, N-Triples and Turtle Terse RDF Triple Language syntax via the Raptor RDF Parser Toolkit.
Storage for graphs in memory and persistently with Sleepycat/Berkeley DB, MySQL 3-5, PostgreSQL, AKT Triplestore library, SQLite, files or URIs.
Query language support for RDQL using Rasqal.
APIs for accessing the graph by Statement (triples) or by Nodes and Arcs
Redland contexts for managing aggregating graphs and recording provenance.
Statement Streams for efficient construction, parsing and serialisation of graphs
rdfproc RDF processor utility program
No memory leaks.
