No need to create a canonical representation and then to check it. There are at least two tools to help you with:
1) rdf-utils allow you to check for diffs in the RDF graph. <http://wymiwyg.org/2005/12/22/announicing-rdf-utils?appendLang=en> 2) KAON2 OWL tools allow you to check for diffs in the OWL ontology that is represented by the RDF graph. <http://owltools.ontoware.org> Both should work out of the box. The latter maybe offers a bit of a higher abstraction, but it fails if both ontologies are not within OWL DL. I didn't try out the former, but as far as I understand the description it should work fine on the triple level, which is probably what you need here. I think neither works on the model, but both work on the RDF structure, which may or may not be what you want. I am not sure if there is a model-aware version of such a tool. I should write one :) I hope this helps, denny Rzepa, Henry wrote: > Assuming we can extract RDF from our SMW, we would like to compare it > logically with some "hand crafted" RDF produced for what we assume is > the same collection of facts. > > What is the best way of comparing two sets of such facts to isolate > discrepancies. Does the concept of canonicalised RDF exist? ------------------------------------------------------------------------- Take Surveys. Earn Cash.
