Discussions

Geoff

We aren't walking through slides. optimizing individual proofs for starting combining (not a rush), Cynthia TODO Combining has been for proofs in logic, but we could combine more general proof like structures (e.g. geology, security) How to apply the technology to something other than logic proofs. Tim still not sure "what features to look for" Geoff - perhaps spend a day to figure it out. Geoff away next week.

Cynthia's hasHash

done: Cynthia added the content negotiation. Now the models are coming in fine. Problem: proper use of things defined in "indirect" document. Cynthia points us to http://inference-web.org/wiki/IW_Meeting_2011-07-14#URI_namespace_points_to_a_html_file In the RDF/XML returned by curl -H "Accept: application/rdf+xml" -L http://www.semanticdesktop.org/ontologies/nfo/#hasHash

 <rdf:Property rdf:about="http://www.semanticdesktop.org/ontologies/2007/03/22/nfo#hasHash">
   <rdfs:comment>Links the file with it's hash value.</rdfs:comment>
   <rdfs:label>hasHash</rdfs:label>
   <rdfs:domain rdf:resource="http://www.semanticdesktop.org/ontologies/2007/03/22/nfo#FileDataObject"/>
   <rdfs:range rdf:resource="http://www.semanticdesktop.org/ontologies/2007/03/22/nfo#FileHash"/>
 </rdf:Property>
 

Problem: http://www.semanticdesktop.org/ontologies/nfo/#hasHash is NEVER MENTIONED in the RDF/XML returned when requesting it.

Note:

 curl -H "Accept: application/rdf+xml" -L http://www.semanticdesktop.org/ontologies/2007/03/22/nfo#hasHash

returns IDENTICAL content as

curl -H "Accept: application/rdf+xml" -L http://www.semanticdesktop.org/ontologies/nfo/#hasHash

TODO: Tim to change ALL uses of http://www.semanticdesktop.org/ontologies/nfo/#hasHash with http://www.semanticdesktop.org/ontologies/2007/03/22/nfo#hasHash TODO: Tim to look for this same type of problem with the rest of NFO usage in provenance tools.

Cynthia how to handle direct references

"static" vs. "dynamic" content Tim: static vs. dynamic Cynthia: the LOOOONG URI for the Information created when Tim loads the triple store. first.ttl.rdf contains the two triples:
