Re: Theorem proving / reasoning using CIF dictionaries

Many thanks Nick,
CIF and DRel are ahead of their time. I find this all the time with CML. noone gets the point.
It's so obvious to you and us and me that published knowledge is computable. But so few people get it. I didn't realise when started withe early dictionaries (what was the precursor of CIF? ) that this was anything unusual. What's amazing is how few other disciplines have adopted the semantic dictionary idea.
I am now starting this with Wikidata, which I think is the future of scientific metadata and can be computed (it's in RDF/SPARQL).
Is there any activity in getting CIF definitions into Wikidata? All the PDB codes are already in.

I think CIF.DRel is a good playground for developing theorem proving

In our original design considerations of how to structure a dictionary and define dREL we explicitly discussed the concept of a knowledge engine trawling the dictionary to find hitherto undefined relations from the definitions - we were blue sky, spit balling in essence but we were confident eventually such a process could be manufactured. 

The realities of mapping ideas around dREL into concrete systems means you make compromises. While we tried to engineer dREL around "relations" it is quite imperative in nature. Not to sure what knowledge engines consume as information these days and whether it has moved on from is_a, has_a etc etc semantic networks or whether programming code is trawlable, but good luck - I would love to see DDL and dREL move to the next level.

cheers

Joe Cornell is a mathematician who is interested in theorem proving starting from semantic definitions. The CIF dictionaries could be an interesting starting point where definitions and executable code are coupled. Do you know of efforts to use CIF to calculate properties or relations that are not explicitly defined in the dictionaries - possible with constraints.

Hope this makes some sense!
