ISSUES

Khalid

• http://www.w3.org/2011/prov/track/issues/267 annotate subproperties
  • The sub-properties were annotated to justify the fact that they are sub-properties. (I sent an email to Tim and Paolo to ask if the related issues 267 can be closed, I haven't received an answer for that).
  • TODO: did he commit them
• http://www.w3.org/2011/prov/track/issues/349 turtle examples in cross ref
  • Khalid made sure that people added all the TTL examples required in the cross references section.
  • Tim: are all comments cleared? Still has yellow and red in spreadsheet.
  • TODO: Tim to review Satya's
  • Tim: we can show Involvement -- how wasConductedBy is understood generically in PROV.
  • Daniel: possible attributes of OriginalSource
  • Tim: I've noticed this same "finding attributes" problem with most of the Involvements.
  • Paul: confidence values on the relation.

Daniel

• http://www.w3.org/2011/prov/track/issues/281 deref namespace
  • http://www.w3.org/ns/prov#  dereferincing namespace will get to a page.
  • Tim: conneg? curl -H "Accept: application/rdf+xml" -L    vs.    curl -H "Accept: text/turtle" -L 
  • http://dvcs.w3.org/hg/prov/file/bc9d5a763ed6/ontology/ProvenanceOntology.owl
  • http://dvcs.w3.org/hg/prov/file/bc9d5a763ed6/ontology/prov.ttl
• https://www.w3.org/2011/prov/track/issues/373 remove qualified from 3.2 expanded

Jun

• http://www.w3.org/2011/prov/track/issues/89 finding attributes CLOSED
• http://www.w3.org/2011/prov/track/issues/344 definitions CLOSED

Stephan

• http://www.w3.org/2011/prov/track/issues/268 two level ontology
  • sent email to group about decision, no response as of yet http://www.w3.org/mid/A3FB311F-AECF-42D0-A5A0-B3CE1B8B1914@rpi.edu
  • possibly ready to be CLOSED
  • TODO send email asking if ready to close (SENT)
• http://www.w3.org/2011/prov/track/issues/363 prov:value collision
  • Stephan: if we break collections to a separate document, then do we use a different namespace?
  • Paul: group all collection info (dm, prov-o) into one document. We've already resolved to use one namespace.
  • Paul: regardless of what document, it's all part of the recommendation.
  • provc:value is clearly not prov:value
  • Tim: use prov-collections as an example of extending prov
  • Stephan: alternate option is to rename object proprty prov:value to prov:keyPairValue or similar
  • Stephan: PROPOSAL: rename datatype property prov:value to prov:content?
  • Paul: too many namespaces causes confusion for developers
• http://www.w3.org/2011/prov/track/issues/338 prov:agent vs hadPlan naming CLOSED

Stian

• http://www.w3.org/2011/prov/track/issues/83 annotate prov:inverse local names
• http://www.w3.org/2011/prov/track/issues/366 approving agent.
• http://www.w3.org/2011/prov/track/issues/334 qual pattern definition

Satya

• For ProvRDF issues, move RAISED issues to either POSTPONED, OPEN, or CLOSED
• http://www.w3.org/2011/prov/track/products/9
  • Tim: be ruthless on POSTPONE
• For Involvement - use non PROV properties (not use specific sub-type of involvement) 

Tim

• http://www.w3.org/2011/prov/track/issues/276 coverage
  • automation still down.
• http://www.w3.org/2011/prov/track/issues/336 latest round of feedback
  • RAISED 44 -> 36
  • PENDING-REVIEW 16 -> 19
  • CLOSED 2 -> 3
  • OPEN 48 -> 50
• http://www.w3.org/2011/prov/track/issues/348 property naming
  • ongoing, describing and documenting is the focus now.
• http://www.w3.org/2011/prov/track/issues/308 w3c style
  • Will close unless somebody objects to the current use of aquarius. Is it holding anybody back?
• http://www.w3.org/2011/prov/track/issues/350 union domains in html cross ref
  • Still not done. Will do this week :-)
• http://www.w3.org/2011/prov/track/issues/371 timestamped owl
  • Still waiting on Jun to clarify what the problem is and what she wants
  • option 1: Tim is going to hg tag the owl file.
    • This gives: http://dvcs.w3.org/hg/prov/raw-file/WD-prov-o-2012MMDD/ontology/ProvenanceOntology.owl
  • option 2: Tim is adding to the automation so that the prov-o.html will point to the OWL version that it used.
  • option 3: <> owl:versionIRI <www.w3.org/TR/2012/WD-prov-o-20120501/ProvenanceOntology.owl>  ?
  • Satya: adding versionIRI into the file itself instead of naming the OWL File directly (owl:version "2012-04-12") owl:versionInfo <ontology IRI>
  • Paul: IRI is better.  Use case is to download it, and use locally. using namespace supposed to use.
  • Tim: support this at every hg commit? Paul: no.
  • Tim: only for WD releases? Paul: yes.
  • Stephan: I prefer versionIRI as well (but do owl:versionInfo as well)

seed issues

How would you encode http://aquarius.tw.rpi.edu/prov-wg/prov-o#acknowledgements in prov-o?

Stephan: Does the removal of responsibilities from dervication deprecate prov:wasApprovedBy? Tim: yes.

New issues

• https://www.w3.org/2011/prov/track/issues/372 qualified prop chains
  • (prov:qualifiedUsage prov:entity) rdfs:subPropertyOf prov:used .
  • Tim tried to add "prov:qualifiedUsage prov:entity -> prov:used", but Protege cut off "prov:entity"
  • prov:qualifiedUsage o prov:entity
  • done: Stephan will send link.
  • Property chains Allow transitivity across multiple properties. For the currently selected property prop3, the editor syntax is prop1 o prop2 [o ...] -> prop3 which means if a prop1 b and b prop2 c then a prop3 c.
  • Looks like it works :-) -Tim
