=======================

[~] familiarize yourself w/ some tooling

	[x] run all queries from ulo paper in virtuoso

	[~] import all data into graphdb

		[x] import coq data into graphdb

		-> had to use a little scritping to remove some
		invalid(?!) parts from the rdf files

		-> used script /ulo/coq-cut.sh

		[~] import isabelle data into graphdb

		-> importing the isabelle rdf files I get an error

			org.eclipse.rdf4j.sail.SailException: Invalid IRI value

		   for all files; I wonder if the proposed IRI
		   scheme is actually illegal; will have to
		   look into that

		-> RDF [1] uses IRIs which "are a generialization of URI [2]";
		   IRIs are also defined by the IETF [3]

	[ ] run all quries from ulo paper in graphdb
