-> https://philarcher1.github.io/sdw/ssn/ My current version of the SSN doc

phila: This includes a *lot* of tweaks, but nothing substantive of course
... mainly adding and fixing the references (which were a royal mess, sorry)
... I need help resolving the broken links in the doc, see https://validator.w3.org/checklink?uri=https%3A%2F%2Fphilarcher1.github.io%2Fsdw%2Fssn%2F&hide_type=all&depth=&check=Check

SSN document

Propose to publish SSN Working Draft http://w3c.github.io/sdw/ssn/ as foreshadowed at F2F https://www.w3.org/2016/12/16-sdw-minutes#item09.

-> https://philarcher1.github.io/sdw/ssn/ My working copy of the doc

phila: I need people who know about SSN to look at https://validator.w3.org/checklink?uri=https%3A%2F%2Fphilarcher1.github.io%2Fsdw%2Fssn%2F&hide_type=all&depth=&check=Check

https://philarcher1.github.io/sdw/ssn/#SSNhasOutput (lines 2305, 2316)

https://philarcher1.github.io/sdw/ssn/#SSNobservedBy (lines 1916, 1926)

https://philarcher1.github.io/sdw/ssn/#SSNhttp://www.w3.org/ns/ssn/Output (line 1605)

https://philarcher1.github.io/sdw/ssn/#SSNhasValue (line 2764)

https://philarcher1.github.io/sdw/ssn/#SSNhasInput (line 2293)

ahaller2: They should be SSN, not SOSA

<Zakim> kerry, you wanted to comment on broken links by irc only

<ahaller2> please post it into IRC

<kerry> reminding I cannot hear

<kerry> the 404 is to an ontology that needs to be deployed in w3 space

ahaller2: Is looking up why those links are borken
... They should be right but they're not

phila: Yes, Kerry, but I don't know which of the *many* RDF files I'm supposed to put there

<kerry> the ones phil has typed in are all specgen-sourced --- I thnk then fixed by armin

<kerry> no -- not many!

<kerry> "ine: 3875 http://www.w3.org/2017/01/ssn-ssnx"

<kerry> that one is new --- on github

Yes, I know the destination, but which RDF file on GH

<kerry> ok -- looking up

<laurent_oz> Phil: specgen generates blank cell in some tables.

<laurent_oz> ... which I have to delete.

<laurent_oz> ... e.g. tables which have two declared columns and then have three

phila: Which of the files at https://github.com/w3c/sdw/tree/gh-pages/ssn/rdf goes in /2017/01?

<kerry> https://github.com/w3c/sdw/tree/gh-pages/ssn/ssn_separated

<kerry> These three are all needed

<kerry> ssn.owl replaces previous

<kerry> dul-alignment is for broken link "ine: 3875 http://www.w3.org/2017/01/ssn-ssnx"

<kerry> No!

<kerry> ssn-equivalences is for broken link ine: 3875 http://www.w3.org/2017/01/ssn-ssnx"

<kerry> dul-alignment replaces previous (ssn-dul)

http://www.w3.org/ns/sosa/ now works

<kerry> and there is one more --- the new sosa

<ahaller2> observedBy defined in SSN http://www.w3.org/ns/ssn/observedBy

ahaller2: Those properties aren't being included by SpecGen as there is no label

<kerry> there is only one fil in the https://github.com/w3c/sdw/tree/gh-pages/ssn/rdf directory --- only sosoa.ttl

<ahaller2> https://github.com/w3c/sdw/blob/gh-pages/ssn/ssn_separated/ssn.owl

No, Kerry, I see *10* RDF files in that GH directory

<kerry> in the rdf directory -- only one file is relevant -- https://github.com/w3c/sdw/blob/gh-pages/ssn/rdf/sosa.ttl

<KJanowic> phila, imho, we only need to care about https://raw.githubusercontent.com/w3c/sdw/gh-pages/ssn/rdf/sosa.ttl , right?

<ahaller2> there are several properties in SSN that are not in the document, because they do not have a label in the ontology: SSNobservedBy, #SSNhasValue , #SSNhasInput, #SSNhasOutput

laurent_oz: It surprised me to see a .owl extension when the content in Turtle
... I'd expect to see .ttl

<ahaller2> kerry, please have a look at them

<kerry> armin --- not sure what you are asking me/

<ahaller2> https://github.com/w3c/sdw/blob/gh-pages/ssn/ssn_separated/ssn.owl

<KJanowic> the raw file: https://raw.githubusercontent.com/w3c/sdw/gh-pages/ssn/rdf/sosa.ttl

<KJanowic> see my link

<ahaller2> http://www.w3.org/ns/ssn/

phila: For clarity, https://github.com/w3c/sdw/blob/gh-pages/ssn/ssn_separated/ssn.owl replaces /ns/ssn

<KJanowic> https://raw.githubusercontent.com/w3c/sdw/gh-pages/ssn/ssn_separated/ssn.owl

KJanowic: Be careful to take the raw files, not the rendered ones

<ahaller2> https://raw.githubusercontent.com/w3c/sdw/gh-pages/ssn/rdf/sosa.ttl

phila: So that one is /ns/sosa/ - done

<ahaller2> https://github.com/w3c/sdw/tree/gh-pages/ssn/ssn_separated

<ahaller2> https://raw.githubusercontent.com/w3c/sdw/gh-pages/ssn/ssn_separated/dul-alignment.owl

<ahaller2> http://www.w3.org/ns/ssn/dul/

<ahaller2> https://raw.githubusercontent.com/w3c/sdw/gh-pages/ssn/ssn_separated/ssn_equivalences.owl -> http://www.w3.org/2017/01/ssn-ssnx

<KJanowic> e.g., http://www.w3.org/ns/ssn/dul-a/

KJanowic: Don't mean to be picky, but I think we shouild call it Dul-A so it doesn't look likem it's the actual DUL ontology
... It's not the namespace for DUL, it's the alignment

phila: I agree, KJanowic, I don't like having alignments in /ns

ahaller2: We discuessed this last time

<kerry> It has not moved --- it was there for FPWd!

<KJanowic> kerry: dul-a is our alignment to dul. ns/dul does not point to dul and we should be careful not to confuse people

ahaller2: Kerry was saying it deserves its own namespace; I don't have an opinion. I like the idea of dul-a but I also like dated space

<kerry> there is nothing dated about that dul alignment

<KJanowic> imho, we do not need a namespace for the alignment but I will be fine with whatever the rest of you like to do

<KJanowic> ok

<kerry> maybe you missed this --- but it is *alrady* in /ns as it was for the fpwd

phila: With hindsight, we'd have done it differently, but, well, we didn't have hindsight.

ahaller2: OK.

Coming back to the missing properties

<laurent_oz> I suggest that in the next version we include a ssn-dul prefix in dul-alignment to make it clear it is not DUL.

<ahaller2> Kerry, can you have a look at them and add them back into the document?

<kerry> armin, yes I can --- I suppose I can just fake the specgen output for them

ahaller2: The problem is that properties don't have labels so SpecGen can't generate, so we need to handcraft

<Zakim> kerry, you wanted to ask what the hell dul-A is? Never heard of it before? and to answer laurent

<ahaller2> please post to IRC!

<kerry> I think the dul-a thing is over

<laurent_oz> OK, kerry I retract what I said (because there is nothing in the file which would use it)

<kerry> but to mention that it is "ssn-dul" --- and that is the prefix

<kerry> was laurent asking for a declaraion of the prefix inside ssn-dul? that could be done.

<laurent_oz> (I was just trying to make it consistent with our use of ssn-ssnxg)

<laurent_oz> Yes, kerry, but see my previous point,

<kerry> yes, there is no ssn-dul used inside the file becuase there are no new terms in the file --- but a prefix statement could be included i suppose if it is useful

<laurent_oz> Phil: I'll use the right extensions for the file .ttl or .owl

-> http://w3c.github.io/sdw/ssn/ Now up to date

<laurent_oz> Memo for the next version: check that all classes/properties have labels.

<kerry> ACTION: kerry to put labels in those ssn terms without them e.f observedBy [recorded in http://www.w3.org/2017/01/04-sdw-minutes.html#action01]

<trackbot> Created ACTION-250 - Put labels in those ssn terms without them e.f observedby [on Kerry Taylor - due 2017-01-11].

<Zakim> kerry, you wanted to ask about references

<kerry> phil mentioned trouble with references

<ahaller2> kerry please post your question

ahaller2: Any other requests for changes?
... or comments?

<kerry> the mostimportant one --- to the ssn paper (which was the only one for fpwd)

<kerry> seems to have gone?

<kerry> cna that be put back ---- is it possible it just disappeared today?

Where's the ref to it in the doc?

Only docs that are referred to make it into the references sectrion :-)

<kerry> ok --- that must be the problem!

:-)

<kerry> well I can add a link if you want or we can do that as an action for next time

<KJanowic> Hmm, I see the ssn paper in the reference section

See https://github.com/w3c/sdw/blob/gh-pages/ssn/config.js

phila: I think all the references are in that config file, but ReSpec ignores anything not cited in the doc

<kerry> So does the group want me to writesomething to use the reference for the vote -- or just leave it to newt wd?

<KJanowic> SSNO

<laurent_oz> In the previous published version was here: Based on this initial work, the following document specifies a revised, modularized, and extended version of the SSN [SSNO].

<KJanowic> That is the reference to the paper not the report

<ahaller2> kerry, there is a reference to SSNO the journal paper, but not to the SSN XG, you want both I suppose?

<kerry> laurent is right --- where did that go?

<laurent_oz> at the end of part 1

<KJanowic> https://www.w3.org/2005/Incubator/ssn/ssnx/ssn is the document

<ahaller2> http://www.w3.org/ns/ssn/

phila: So the final sentence of part 1 should say Based on this initial work, the following document specifies a revised, modularized, and extended version of the SSN ontology. [SSNO]
... and that links to https://www.w3.org/2005/Incubator/ssn/ssnx/ssn

<KJanowic> we are confusing document and paper

laurent_oz: The SSNO link pointed to the journal paper, not to the generated documentation
... i.e. it was to

<laurent_oz> SSNO = Michael Compton; Payam Barnaghi; Luis Bermudez; Raúl García-Castro; Oscar Corcho; Simon Cox; John Graybeal; Manfred Hauswirth; Cory Henson; Arthur Herzog; Vincent Huang; Krzysztof Janowicz; W. David Kelsey; Danh Le Phuoc; Laurent Lefort; Myriam Leggieri; Holger Neuhaus; Andriy Nikolov; Kevin Page; Alexandre Passant; Amit Sheth; Kerry Taylor. Web Semantics: Science, Services and Agents on the World Wide Web, 17:25-32 . The SSN ontology of the W[CUT]

KJanowic: Let's use the SSNO link that points to the article for now

ahaller2: That's in the config file, so just add [[SSSNO]] to the end pf part 1

PROPOSED: To publish the SSN document as at http://w3c.github.io/sdw/ssn/, with addition of link to SSNO at the end of part 1, and relevant RDF files being put in place/updated; plus addition of missing SSN properties

<ahaller2> kerry, please post your question?

phila: We have proxy votes from Linda, Ed, Scott, Bill, Rob, Raphael

<kerry> re "updated" in motion

<kerry> is hter anything to update? in rdf files/ - I don't think so

phila: No, nbothing to update in the files, but I need to update the w3.org copies/put them in place

<ahaller2> there should be updates later to SSN to include labels with the properties, but that is ok for now

<ahaller2> those five properties that have missing labels

<ahaller2> but, I will handcraft that for the document

<kerry> so there are no "updates" to rdf files for the vote, right?

<ahaller2> no updates to the RDF files

Correct, Kerry

<kerry> good

<laurent_oz> Have we change ssn-bc to ssn-ssnxg in ssn-equivalence ?

<kerry> also there are some more proxy votes:

phila: Yes, laurent_oz

PROPOSED: To publish the SSN document as at http://w3c.github.io/sdw/ssn/, with addition of link to SSNO at the end of part 1, and relevant RDF files being put in place/updated; plus addition of missing SSN properties

<ahaller2> +1

<kerry> +1

<MattPerry> +1

<laurent_oz> +1

<DanhLePhuoc> +1

phila: We have proxy votes from Linda, Ed, Scott, Bill, Rob, Raphael, so +6

<KJanowic> +1

RESOLUTION: To publish the SSN document as at http://w3c.github.io/sdw/ssn/, with addition of link to SSNO at the end of part 1, and relevant RDF files being put in place/updated; plus addition of missing SSN properties

<KJanowic> Thanks phila,ahaller2 for getting us through that!

<ahaller2> please post quickly

<kerry> who will fix the doc dor missing properties?

<ahaller2> missing properties I will fix
