Discuss progress of current sprint based on the Sprint Plan

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

ACTION-242

(Restructure the document to move the summary to the top and remove the template)

Linda: Restructuring is done, BP overview is now chapter 4
... action is complete

ACTION-232, ACTION-233

<Linda> ClemensPortele: is done, except that links to issues are still in the draft.

ClemensPortele: actions done, no comments received
... issues could be closed

Action Linda to review whether the issues can be closed

<trackbot> Created ACTION-260 - Review whether the issues can be closed [on Linda van den Brink - due 2017-02-08].

Linda: Everyone should review the changes (like all other changes)

ACTION-234

ClemensPortele: schema.org snippet is included, but statistics on schema.org Place is missing
... needs to wait for Ed's input

ACTION-247 Rewrite of section 7 Coordinate Reference Systems

Linda: Done, rewrite done by Ed and now in the Editor's draft
... some parts were left out as too detailed for the audience

ClemensPortele: detail seemed sufficient to me

Linda: again, everyone to review

ACTION-241 Further work on best practices 3 and 18 about Coordinate Reference Systems (possibly merging them)

Linda: Byron is working on it, no pull request, progress unclear

Action Linda to ask Byron about progress on ACTION-241

<trackbot> Created ACTION-261 - Ask byron about progress on action-241 [on Linda van den Brink - due 2017-02-08].

ACTION-248 Further work on BP7 (use HTTP URIs) + BP14 (Links to related resources)

Linda: jtandy reported that he wants to work on it over the weekend
... should be part of the next release

ACTION-249 Further work on BP8 (geometry)

AndreaPerego: Had a call with jtandy about the changes
... will work on this next week, we should have something ready in two weeks
... plans to make changes in fork in his own repository so that everyone can review before merging into the Editor's draft

Linda: sounds good

AndreaPerego: There has been a discussion on the email list and in the last meeting that will have an impact on the BP
... also we should add to the glossary, e.g. on "dimension"
... there is a specialist definition in the ISO-based glossary, but we should also have something for the non-specialist

Linda: yes, this is one of the terms we take for granted

ChrisLittle: my working definition is what is in the RDF Data Cube
... other work by Rob Atkinson as well as Peter Baumann (WCS)
... probably same meaning, but in some cases "dimension" is reduced to coordinate dimension
... but, e.g., "species" can be a dimension, too

AndreaPerego: Please provide a link to the Data Cube definition

ChrisLittle: Will do

AndreaPerego: I will add candidates for discussion in my fork so we can discuss it

ChrisLittle: This is raised also in the OGC as it is relevant for map services

Linda: so this action will not be ready for the next release

AndreaPerego: probably yes, but it should be ready for the next release

Other actions for this sprint

Linda: None working on BP1, so this will not be part of the sprint
... ACTION-240 Remove BP17 (crowdsourcing) from BP document is done. Some text has been moved elsewhere (BP1)
... ... in examples
... ... also ready for review

Outreach for wider review

Linda: task on Ed and Phil
... ... progress is unclear
... Recap - most issues are done and wait for review
... when should we freeze? Proposal: Monday morning (would include actions 248, but not 249, 241 unclear)
... ... thoughts?

<AndreaPerego> +1 to ClemensPortele

ClemensPortele: I think we should stick to our time plan

<ChrisLittle> +1 to freeze

PROPOSAL: Freeze edits on Monday morning

<AndreaPerego> +1

<Linda> +1

<ClemensPortele> +1

Action Linda to update BP sprint plan accordingly

<trackbot> Created ACTION-262 - Update bp sprint plan accordingly [on Linda van den Brink - due 2017-02-08].

discuss contents of next sprint

Linda: next week to next f2f meeting
... See backlog https://www.w3.org/2015/spatial/wiki/Detailed_planning_BP_document#Backlog_-_To_do
... highest priority comes first in the list
... BP1 was discussed in London and we need address the points made there
... ... see https://github.com/w3c/sdw/issues/520
... ... discussion probably needs a larger group than we have today, but it should be in the next sprint

<ClemensPortele> +1

<Linda> +1

<AndreaPerego> +1

<ChrisLittle> +1

<ScottSimmons> +1

Linda: Next one for the next sprint would be BP10 (spatial semantics). A choice between vocabularies, or a good method for selecting the right vocabulary for a specific use, is needed. See https://github.com/w3c/sdw/issues/39 and https://github.com/w3c/sdw/issues/214.
... ... should be in the next sprint, too

<ClemensPortele> +1

<Linda> +1

<ChrisLittle> +1

<AndreaPerego> +1

Linda: One question is who wants to work on BP10 and has ideas?

AndreaPerego: This is general and affects also how we select how we represent geometries

Linda: The work on the spatial ontology will take longer than the BP work

AndreaPerego: Then we should show how things are done today (examples)
... ... will make a proposal in the ongoing work on BP8

Linda: currently no owner for BP10, but we agree it is a key issue
... Anyone willing to own BP1?

(silence)

Linda: Next is BP2 (provide context required to interpret data values, https://github.com/w3c/sdw/issues/384)
... ... can it be removed, covered by DWBP already?
... ... could also be in a future spint
... Also no owner at the moment

<ChrisLittle> My ACTION: here is the link to the W3C RDF (non) definition of Dimensions: http://www.w3.org/TR/vocab-data-cube/

Linda: Next is chapter 11 (how to use these best practices, https://github.com/w3c/sdw/issues/381)

<AndreaPerego> Thanks, ChrisLittle !

Linda: Any topic on the backlog where we have a volunteer?

tidoust: question on the time line - based on the current plan after this spring there will mainly be editorial changes
... ... so everything where we do not have a volunteer for the next sprint, we won't get it into the BP document

Linda: yes, this correct - please consider this

Action Linda to send email to the WG to remind everyone to volunteer for the next sprint, otherwise it is in danger of being dropped from the BP document

<trackbot> Created ACTION-263 - Send email to the wg to remind everyone to volunteer for the next sprint, otherwise it is in danger of being dropped from the bp document [on Linda van den Brink - due 2017-02-08].
