NAME
Redland Resource Description Framework (RDF) Library
VERSION
\s-11.0.3\s0
SYNOPSIS
#include <redland.h>
DESCRIPTION
redland is a library providing support for the
Resource Description Framework (\s-1RDF\s0) written in \s-1ANSI\s0 C with
APIs in several other languages.
This manual page lists most of the redland public \s-1API\s0 functions but
does not claim to be a complete summary of the entire \s-1API\s0. For the
complete \s-1API\s0 with full details of the function interface, see the
\s-1HTML\s0 \s-1API\s0 documentation either on the Redland web site at
<http://librdf.org/> or with the software release in the docs/api
directory.
FUNCTIONS
The functions defined by redland are all defined with the
CWlibrdf_ prefix

class concepts
The library provides macros for all of the \s-1RDF\s0 and \s-1RDFS\s0 concepts -
nodes and URIs. For example, CWLIBRDF_MS_Alt for the librdf_node
for the rdf:Alt concept and CWLIBRDF_MS_Alt_URI for the librdf_uri
for the \s-1URI\s0 reference of rdf:Alt.
CWLIBRDF_URI_RDF_MS and CWLIBRDF_URI_RDF_SCHEMA provide the librdf_uri
objects for the \s-1RDF\s0 and \s-1RDFS\s0 namespace URIs. They must be copied
using librdf_new_uri_from_uri to be shared correctly.
