Progress towards the 3 FPWD - EO-QB, QB4ST, CovJSON. How close are we to candidate FWPD on each of these?

bill" covjson plan to fill in a lot of the gaps

scribe: call with Jon Friday and exepct to meet monday morning stabe doc

as to plan

scribe: but have some questions...

<billroberts> http://w3c.github.io/sdw/coverage-json/

billroberts: couiple of sections that I am asking about
... section 6 use cases and requirements
... thinking of exaplining how covjson maps to requirements
... saw that other docs have not done it in a lot of detail
... is this appropriate?
... necessary? useful?

phila: yes it is necessary
... you must show you have met requirements
... a section in each document to do this is useful
... it needs to be in all

billroberts: will do

roba: was planning to do same for qb4st
... but question about style ...OGC provides more rationale of technology where W3C is terse.. what do we do?

billroberts: also for covjson --- we need to say "why we are making another standard for coverages"

phila: would include some verbage around motivation
... also relationship to previous work would be good
... like time --- why it is different to before
... beyond that entirely up to you
... no rule that yo cannot include explanation --- you should do it if you think so especially if expected of OGC papers

roba: qb4st will retain why you need anything at all

phila: inapprop to write non-normative in docs as whole doc is non-normative

dmitrybrizhinev: non-normative comes by defualt -- cannot remove it -- is there another one?

phila: yes ... you should not use informative class so ... dont' use section class = informative

billroberts: covjson may have an appendix that contains [missed] so that the same doc has everything in it and not externally referenced

<billroberts> https://covjson.org/spec/

phila: billroberts question it is odd to have covjson standard body with an appensix that is the specification

s.appendix/apendix/

phila: will look inot ithis

billroberts: will talk to jon about how much the covjson spec might change -- it does not look tremendously final right now

roba: suggests you copy the spec in in full status

billroberts: but how close to final is it? in final version of note this could be the definitive version of spec

phila: leave this to editors draft link.... their doc does not have ipr committments, so that repo spec could be implemented with royalties lurking
... so I am reluctant to give that doc credit, but we could incluide a link somewhere...

roba: previous version link?

phila: no but something in the status of the repo doc to point to our Note that points it as a static version and that this version may be an update
... legal stuff matters a lot
... a link to that one is the best you can do -- there are places you can link but it will not go through process and IPR

billroberts: will work through that with Jon, seems like we should wrap up that spec and put it in this note

phila: yes, if the full content goes in our note
... must give full endorsement in our note but IPR constrains us

roba: could transcribe the bulk of it directly into our Note

<phila> s/ but we could include a link somewhere/ but we could certainly include links somewhere.../

billroberts: respec references: if we need a ref that is not elsewhere whre do I put it?

phila: in local biblio = config.js

<phila> This file, bill

phila: it shows how to do it there -- an ssn one is thre

billroberts: are we sharing a common biblio?

phila: just copy and paste between config.js

billroberts: doc number?

roba: offers to check on OGC doc number

Topcic: eo-qb?

eo-qb

<roba> 16-125 Publishing and Using Earth Observation Data with the RDF DataCube and the Discrete Global Grid System

<roba> but i dont see covjson yet..

dmitrybrizhinev: pretty good shape, includes refs to use cases and requirements, we have description to rdf on example, als some new detail with implementation, has updated qb-4st

billroberts: what do we have to do in a formal sense?

phila: day 1 of f2f will be vote -- it ha become the norm that the group is given a week to review it

<roba> shall I generate one then?

eo-qb lokks ready for review to me

billroberts: if there isn't one and you can make one --- can you pls? for covjson

roba: title is currently "coveragejson" but it can be changed
... usually more descriptive than that -- what do you want?

<roba> The CoverageJSON Format Specification

roba: [suggested a name] and bill agreed

phila: asks about geojson's name
... likes "coveragejson" name
... dmitry
... could this end up a rec -- could there be another implementation for rec?

dmitrybrizhinev: but is more of guidance -- a wroked example -- than it is for a standard

<roba> You have successfully reserved 16-145 for The CoverageJSON Format Specification.

billroberts: on eo-qb will send round an email to draw attention

roba: minor changes around qb4st

Kerry: will do

roba: other comment is if using rdfdatacube --- statment about using for data and metadata should be higher up
... is more significant than where it is

<Zakim> phila, you wanted to ask about the namespace http://resources.opengeospatial.org/def/qbcomponents/qb4st/

phila: ... 2 things -- the namespace is very long... can it be shorter ... when I refernce it I get an error

<phila> I can offer you http://www.w3.org/ns/qb4st

roba: namespace is not fixed yet.... currently mutable... what should they be .. can be changed to a target

phila: can give you one

roba: will adopt what you give me

phila: want to see the final name space in the FPWD

roba: happy eith that

<Zakim> Kerry, you wanted to ask a realted question about ssn

billroberts: so when will qb4st be ready

roba: wanting some more review

billroberts: will leave to you to mail the list

roba: there has been close review of the concept by dmitry, chris, kerry etc but would like a closer look at the ontlogy itself
... but can throw it out as public draft and see

phila: we should contact Cyganiak and Reynolds to review

roba: did talk with reynolds again about the concept but not the detailed design
... would welcome a closer inspection

billroberts: any other thing to agree for next meeting?
... rob would you lie to see someone lese summarise and present for you?
