Paul: 2 blog posts in the last week - see links above

<dgarijo> yes

<stain> yes

Thanks to Daniel and Stain for two additional blog posts

<dgarijo> no problem :)

They will be posted in the next week

PROV-SEM

Paul: review of outstanding items

<pgroth> james?

Paul: is PROV-SEM ready to be sent out for review?

<jcheney> just tried calling in will try again

<jcheney> sorry

Moving to another item

PROV-Overview

Paul: Not ready - edits not finished - more time needed - hopefully can sent out by Monday of next week

PROV-XML

Update from Stephen

zednik: is ready for review but is missing the FAQ entry

but the note content is ready for review

Paul: is the schema finalised?

Stephen: yes but FAQ may introduce a modification to the new schema but not a change to the schema - so my intention that it is finalised

Paul: review by what date?

Stephen: staged last night - not sure

Paul: original reviews by 4 and changes by 15
... if reviewed by 11 can you incorporate changes by 15

Stephen: hope so - small changes ok - but 11th and 15th should work

Paul: reviewer?

<Luc_> +1

<pgroth> +1

<TomDN> +1

Paul: any responses from our last publication of it?

? from Luc

Paul: will try to get someone from Oracle to take a look

and would be good for Henry to review

PROV-AQ

<SamCoppens> My review is following tonight

Graham: we have reviews in now from Stain and Luc - not one from Sam yet - had a cursory look at the review - not aware of any blocker there

<SamCoppens> but no blocking issues from my side

Graham: plan to review in detail in the coming week and finalise the document by this time next week - and then aim to hand over to Paul to finish up as will be out of circulation in 2 weeks time

Paul: Stain and Luc, could we vote to be a final note?

Luc: we want to publish the note - some comments are more serious than Graham said - related to ping back - would like to see some responses to my comments

Sam: read the document today - will send review tonight - no blocking issues

<GK> I'll need to look in more detail at Luc;s comments, and the others - I'll respond when I do so.

Stain: no blocking issues but some of my issues are more serious

Paul: then let's wait for next week for the vote

to ensure issues are addressed before vote

James: need reviewers for PROV-SEM

PROV-SEM

<jcheney> draft almost done: https://dvcs.w3.org/hg/prov/raw-file/default/semantics/releases/NOTE-prov-sem-20130430/Overview.html

<GK> I'd like to review PROV-SEM, but cannot be sure I'll have time in the coming week.

James: vote on everything next week?

Paul: yes (if not today)

James: better if reviewers can look now rather than waiting for it to be completely done

<khalidBelhajjame> I ll review it

Paul: reviewers

<smiles> I can review it

Tom: a colleague (logic/maths background) and Tom will review

<Paolo> when is it due again?

<GK> I'd like to review PROV-SEM, but cannot be sure I'll have time in the coming week

Paul: review due by next Thursday

<Paolo> would love to but on leave, sorry...

<satya> I will try to complete

James: goal to have something complete - anything controversial will have to be left out

Luc: What change has been regarding this issue [?]

James: to get semantics general enough to not constrain the formal constraints - less of the connection to the inituitve model but necessary
... takes a while to figure out the right way to do that

<pgroth> reviewers - Tom, Khalid, (tom's colleague), simon, satya,

<Luc_> +1 will attempt a quick review

PROV-Primer

Simon: received some reviews - only outstanding is from Craig
... don't see any blocking issues - will make the changes by next week - timeframe is okay

<khalidBelhajjame> It read well, no comment really

Paul: agree, only a need for some minor changes
... vote now

<pgroth> proposed: release prov-primer as a final note

<ivan> +1

<khalidBelhajjame> +1

<GK> +1

<jcheney> +1

<zednik> +1

<satya> +1

<SamCoppens> +1

<Paolo> +1

<Luc_> +1

<pgroth> accepted: release prov-primer as a final note

<smiles> Great, thanks :)

PROV-DC

Paul: congrats Simon and Yolanda

- received a couple of reviews - no blocking issues

- missing a review by Stain

Stain: almost finished - some changes re mapping but should be able to be done in the week

Paul: given that, do not want to vote now
... Tom's review was very long. What was the main issue?

- issue with how we declare the classes - specialising the ontology and also a lot of editorial issues with intro and also with naming spaces - no criticism of the mapppings - so i think no blocking issues

Paul: Stain, which mapping to change?

Stain: the is version

- analysed defns and realised they are equivalent - version and revisions {/}

- not necessarily a directional element - don't want to go into the detail now

Paul: only one?

- yes

Paul: debate the issue online and delay the vote to next week

PROV-Dictionary

<Luc_> +1

Craig: review from Luc and Simon, thanks, no blocking issues, have enough time, give an update next week, do not forsee problems

<Luc_> +q

Luc: in my review, indicated I have implemented PROV-Dictionary, but it turns out it was not working - it took a while to find problem - extensibility production and the new productions conflict
... problem will also occur in PROV-LINKS
... fix in both

Craig: suggest holding off on voting until the document is in a more final state

Craig = Tom

Luc: agree useful to have time to discuss issues further

PROV-Links

<zednik> I have to leave now

Luc: 4 reviews received - thank you - have not had time to read them in detail - but you seem to be happy with the document - some small changes

<smiles> No blocking issues from me

<TomDN> none from me either

<GK> No blockers that I recall

<khalidBelhajjame> No bloking issues from me either

PROV Implementations

Paul: held it open a little longer - nothing to change in the text - just to rerun scripts to update the tables (essentially) - no need to review

<ivan> +1

<Luc_> +1

Paul: one or two people who said they want to register another implementation
... there is still time

Provenance of Docs

<Luc_> +q

Paul: status?

<Luc_> https://dvcs.w3.org/hg/prov/raw-file/e1fa26593295/provenance/test/prov-family.svg

<Luc_> https://dvcs.w3.org/hg/prov/raw-file/e1fa26593295/provenance/test/prov-family.ttl

<Luc_> https://dvcs.w3.org/hg/prov/raw-file/e1fa26593295/provenance/test/prov-family.provn

Luc: tried to recreate the history of all our documents assuming the specs were out

<ivan> wow

<GK> Third link returns "error: provenance/test/prov-family.provn@e1fa26593295: not found in manifest" for me

Luc: covering all versions of the reports we publish - will ask all editors to check when finalised - also should add authorship - do we have URIs for everybody?

Paul: Ivan, can we use URLs for the name in the tracker to represent people?

<Paolo> @Luc: provn version, I get: error: provenance/test/prov-family.provn@e1fa26593295: not found in manifest

<GK> How many of us have ORCID IDs?

<pgroth> http://www.w3.org/2011/prov/track/

Ivan: hmm, it can be used ... but ... often people put a page about themselves on the wiki ... can you give me an example URL to look at in tracker?
... not ideal

<TallTed> WebID! :-)

<stain> you would have hoped for W3C to provide an ontology or dataset of every member!

Paul: wiki user pages?

<pgroth> http://www.w3.org/2011/prov/wiki/User:Ctrim

<Luc_> http://www.w3.org/2011/prov/wiki/User:Lmoreau

Ivan: not sure those are public
... what I was suggesting - if they are all complete that is fine
... they will be frozen

<stain> in foaf they might or might not be seen to represent accounts rather than people..

Paul: use wiki ones - so if you want your proper info recorded update your wiki page

Luc: fine with that

<stain> it might be easiest to identify people like [ a prov:Person, foaf:homepage <http://www.w3.org/2011/prov/wiki/User:Lmorea> ]

<stain> foaf:homepage is inverse functional, thus identifying (but not being) the person

[?] useful to add the link from the RDF files ...

<pgroth> s/RDF/RDF

Paul: can we do content negotation on SVG?

Ivan: not exactly - not a serialisation

Luc: when the file is more or less finalised - post a blog explaining provenance - could put the SVG file there

<stain> you COULD define a prov-diagram that is a formal language that says how to describe prov-dm as a diagram - and then the SVG could still be a representation of the provenance

<TallTed> possibly better pages than wiki -- e.g., https://www.w3.org/users/42501

Ivan: could point to as wekk

<stain> TallTed: except they are seeecret :(

<pgroth> secret

<TomDN> I get Sorry, Insufficient Access Privileges

<GK> No, browser is asking for login

<Luc_> up to editors

Simon: re provenance for primer - what is the preference?

Luc: editors can decide to use the same provenance, don't have to

Paul: thanks everyone, good work, keep it up

<dgarijo> @Simon: we did already a file for prov-o. You can base yours in that one, if you want

Ivan: votes ends on Tuesday - well send an official transition request to publish - expect to get green light by email - try to take care of this next week

<dgarijo> bbye

<Luc_> bye

<GK> Bye

<stain> bye

<SamCoppens> Bye!
