OVERVIEW

   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:
     * A modular, object based library written in C
     * Perl,  Python, Tcl, Java, Ruby and PHP interfaces for manipulating
       the RDF graph and parts - Statements, Resources and Literals
     * Parsers and Serializers for reading and writing RDF as syntax.
     * Storage  for  graphs in memory and on disk via Sleepcat / Berkeley
       DB.
     * Query  APIs  for  the graph by Statement (triples) or by Nodes and
       Arcs
     * Statement  Streams  for construction, parsing, de/serialisation of
       graphs
     * Start of query language support.
     * No memory leaks so far.
