Installation

For the inferencing, a special branch of rdflib is needed:

## don't install this stuff system-wide, use virtualenv
virtualenv foo
. ./foo/bin/activate

## install the prerequisites
pip install pyparsing
pip install -e svn+http://python-dlp.googlecode.com/svn/trunk/layercake-python#egg=rdflib
pip install hg+https://fuxi.googlecode.com/hg/#egg=fuxi

## install this package from git
git clone git://github.com/wwaites/graphmin.git
cd graphmin
python setup.py develop

Example

Running this example:

graphmin -i examples/ex1.n3 -f n3 -r examples/rdfs-rules.n3

Should give this result:

@prefix eg: <http://example.org/>.
@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>.

eg:a a eg:A.

Because the statement eg:a a rdfs:Resource in ex1.n3 is entailed by the RDFS inference rules.
