… a little-language for analysing graph-structured data, especially RDF. The syntax of GraphPath is reminiscent of Xpath. It has a python implementation that can be teamed up with your favourite python RDF API (e.g. Redland, rdflib, or your own API).
Anyone tried it? Apparently it has a rule/inference system too (backward chaining). I don’t quite see how namespace abbrevations are handled, but guess there must be some mechanism for registering them in the API. Could be a candidate for transliteration into Ruby?
I’ve used it with rdflib to do some simple inference based on schemas. For application specific reasons, I’ve handled namespace abbreviations myself, but as far as I can tell, rdflib takes care of them…
The rules can express anything that doesn’t involve an anonymous/variable property, but with a bit of python code around it, all the RDF schema rules can be expressed.
It’s a really nice way to work with RDF in Python. And of all the inference engines I’ve tried to integrate, it’s by far the easiest…
