librdfa - The Fastest RDFa Processor on the Internet

librdfa is a SAX-based RDFa processor written in C for XML and HTML family languages. It currently supports XML+RDFa, XHTML+RDFa, SVG+RDFa, HTML4+RDFa and HTML5+RDFa for both RDFa 1.0 and RDFa 1.1.

Building and Running librdfa

Make sure that you have the following software installed on your system before attempting to build librdfa:

autoconf
automake
gcc
make
pkg-config
libtool
libxml2-dev

Make sure you have the following packages installed if you're attempting to build the Python RDFa libraries:

g++
python-dev 
swig

Make sure you have the following packages installed if you are attempting to build the Debian/Ubuntu packages:

dpkg-buildpackage
dpkg-dev
python-all-dev 
dh-buildinfo 
debhelper

Change into the librdfa source directory and run the following:

./autogen.sh
./configure
make
./tests/speed 

If everything goes well, the speed test should be able to crank through documents at 32 MB/sec and generate roughly 6.5k triples/sec.

Optionally, you can build the Python bindings with the following:

./configure --enable-python
make

Development

pkg-config support is provided to setup cflags and libs. The .pc file is installed along with development files. Add the librdfa source dir to the PKG_CONFIG_PATH environment var to use the uninstalled library.

Building a simple program using librdfa pkg-config support:

cc `pkg-config --libs --cflags librdfa` -o test test.c

Installation

Use configure options to setup install directories. For more information:

./configure --help

To install:

make install
