Documentation section 4

<Phila-offline> Apologies - BT Broadband problems (the two are synonymous)

SimonCox - concerned that documentation e.g. http://w3c.github.io/sdw/ssn/#d4e892

still makes reference to 'Situation' which is DUL concept

Kerry: yes, still based on the original SSN documentation

<KJanowic> SimonCox: Maybe add more warning to make clear that this documentation will be replaced (in some places).

<ahaller2> +1 for a caveat on top

<scribe> ACTION: Danh to add caveat related to documentation replacement [recorded in http://www.w3.org/2016/05/17-sdwssn-minutes.html#action01]

<trackbot> Created ACTION-170 - Add caveat related to documentation replacement [on Danh Le Phuoc - due 2016-05-24].

Danh: Some missing pieces of documentation, e.g. skos:exactMatch?

would have to be done manually

<Kerry> ACTION: danh to write a caveat around ssn doc section to go into ed draft to explain the doc will change in accordance with changes of the ontology but refelct ssn as it was [recorded in http://www.w3.org/2016/05/17-sdwssn-minutes.html#action02]

<trackbot> Created ACTION-171 - Write a caveat around ssn doc section to go into ed draft to explain the doc will change in accordance with changes of the ontology but refelct ssn as it was [on Danh Le Phuoc - due 2016-05-24].

some dc:source information is not carried through to automatically generated LODE documentation

Kerry: since documentation is only in 'annotation' properties does not matter ...

<KJanowic> josh: fine as long as we agreed that this draft will not later limit our proposed changes.

josh: conflicting priorities - intent to re-factor (modular, O&M alignment, PROV alignment) vs. need to get FPWD out, despite content issues - we are wll clear that FPWD is not a constraint on future revisions

http://w3c.github.io/sdw/ssn/#Work Plan and 'Status' section

<phila> I did a *lot* of manual editing... so I probably introduced more than one error.

<KJanowic> Aren't we running into problems by rushing this; If we put out the FPWD and people start commenting on issues that will not make it into the final version anyway?

Armin: typo in condition description?

<phila> <a name="blah"></a> is *so* last century...

+1 @KJanowic

<Kerry> ACTION: danh to fix "dition" class [recorded in http://www.w3.org/2016/05/17-sdwssn-minutes.html#action03]

<trackbot> Created ACTION-172 - Fix "dition" class [on Danh Le Phuoc - due 2016-05-24].

<Kerry> Sefki saying that ssn is only human-readable, nor machine readable

Sefki: propose major refactor for 'timeline' support

@KJanowic - do you want to join q?

"<KJanowic> Aren't we running into problems by rushing this; If we put out the FPWD and people start commenting on issues that will not make it into the final version anyway?"

KJanowic: group agrees that there will be major changes, so should not issue working draft, so as not to waste people's time commenting?

Kerry: group lifetime is a pressure - need to publish early and often - plenty of precedent for draftier drafts in W3C

Purpose of FPWD is to solicit comment

Timeline was set in Dec 2015, Feb 2016

ALready one month late

There is no realistic alternative ...

<SefkiKolozali_Unis> My question was about local restrictions vs global restrictions. Since SSN Ontology is using global restrictions, SSN Ontology is missing domain and range definitions for properties. This can causes some problem when one is parsing the ontology or mapping the ontology into a library.

scribe: but must be sure of support for publishing current draft

<Kerry> +q

<KJanowic> @Sefki: guarded domain and range restrictions were added on purpose vs global domains and ranges

Armin: add comment that modularization does not yet represent the ultimate intention

Kerry: all in http://w3c.github.io/sdw/ssn/#Work Plan

Armin: modularization until now only relates to splitting out DOLCE, not the other re-factoring

<roba> Needs to be in introductory/scoping section

Task: Armin to write words to explain intentions around modularization, RDFS

<Kerry> ACTION: armin to write a little more about modul,arisation re currnet state [recorded in http://www.w3.org/2016/05/17-sdwssn-minutes.html#action04]

<trackbot> Created ACTION-173 - Write a little more about modul,arisation re currnet state [on Armin Haller - due 2016-05-24].

URL for SSN & SSN-DUL

Currently https://www.w3.org/ns/ssn/

Modularisation section 3

modularization

http://w3c.github.io/sdw/ssn/#Modularisation

SimonCox: segmentation text is rather hard to read - could it be improved (examples?)

<Kerry> ACTION: armin to add examples to modularisation [recorded in http://www.w3.org/2016/05/17-sdwssn-minutes.html#action05]

<trackbot> Created ACTION-174 - Add examples to modularisation [on Armin Haller - due 2016-05-24].

SimonCox - 'horizontal' vs 'vertical' a bit abstract

<josh> +1 - the spatial analogy has little meaning. Axiomatic versus subclass dimensions makes more sense

<KJanowic> I simply forgot to consider that, sorry. Happy to change this.

<KJanowic> The wiki ahaller2 pointed to: https://www.w3.org/2015/spatial/wiki/SSN_core_modules

<roba> +1

Armin: "/" URIs proposed to best support modularization
... including URIs for modules

<Kerry> Work Plan section 5

Work Plan Section 5

http://w3c.github.io/sdw/ssn/#WorkPlan

Any other burning and essential FPWD issue

no reponse

SefkiKolozali_Unis: relationship with sensors/IoT
... still unclear how to contribute

https://www.w3.org/2015/spatial/wiki/Proposals_for_rewriting_SSN

DanhLePhuoc: add diagrams in Section 4 to explain relationship to patterns etc

Kerry: too late
... but if you can add diagrams to Wiki, will be added to next version

<KJanowic> +1 for SamplingFeature. I also added this to the SSN core proposal: https://www.w3.org/2015/spatial/wiki/SSN_core_modules

<scribe> ACTION: Kerry to add Sampling Features in Issue biox [recorded in http://www.w3.org/2016/05/17-sdwssn-minutes.html#action06]

<trackbot> Created ACTION-175 - Add sampling features in issue biox [on Kerry Taylor - due 2016-05-24].

<josh> Perhaps it just seems something to do "after" re-factoring

<Kerry> ACTION: kerry to put issue box around sampling features [recorded in http://www.w3.org/2016/05/17-sdwssn-minutes.html#action07]

<trackbot> Created ACTION-176 - Put issue box around sampling features [on Kerry Taylor - due 2016-05-24].

<Zakim> phila, you wanted to talk about issues

phila: make formally tracked issues consistently
... it is essential that issues are tracked, and that we link to them

WHat is mechanics to add items to tracker?

<Kerry> w3c tracker it is

<phila> issue: Align SSN to to implement Best Practices as defined in our BP deliverable.

<trackbot> Created ISSUE-42 - Align ssn to to implement best practices as defined in our bp deliverable.. Please complete additional details at <http://www.w3.org/2015/spatial/track/issues/42/edit>.

issue: Add treatment of Sampling Features in SSN

<trackbot> Created ISSUE-43 - Add treatment of sampling features in ssn. Please complete additional details at <http://www.w3.org/2015/spatial/track/issues/43/edit>.

<josh> bye

<KJanowic> Thanks, bye bye

<ahaller2> hi byron

<roba> bye

<ahaller2> bye

<SefkiKolozali_Unis> bye

<RaulGarciaCastro> Bye!
