Call for editors for Time and SSN

kerry: asks for volunteers

<KJanowicz> Happy to help editing the SSN

kerry: contact Kerry or Ed, if you are interested
... there is interest already, but please come forward, if you are interested

UCR: Strategy to resolve issues for PWD approval 9 December

kerry: goal is clean up and new public draft
... ...then OGC and W3C processes
... ...should take roughly 9 days to get them through both organisations
... ...reminder this is not the final version, but should become more and more stable

BartvanLeeuwen: is there room for new use cases?

frans: yes, until the document is final there is room, but the sooner the better

BartvanLeeuwen: hopes to have it before the end of the year, so probably after the 2nd PWD
... it is already recorded as an action (ACTION-89?)

kerry: match the use case and the products

frans: tracker has matches, some issues are still open - with a discussion thread
... proposing to shift responsibility for resolving from UCR editors to the editors of the other deliverables

<frans> ISSUE-15: time

<trackbot> Notes added to ISSUE-15 Time req. not clear - represent past, present and future.

<frans> ISSUE-18: coverage

<frans> ISSUE-19: coverage

<frans> ISSUE-20: SSN

<trackbot> Notes added to ISSUE-18 Model Reuse.

<trackbot> Notes added to ISSUE-19 Multiple types of coverage requirement.

<trackbot> Notes added to ISSUE-20 Reference external vocabularies.

<frans> ISSUE-23: BP

<frans> ISSUE-24: SSN

<trackbot> Notes added to ISSUE-23 phrasing of the spatial operators requirement.

<trackbot> Notes added to ISSUE-24 clarification of lightweight APIs requirement.

<frans> ISSUE-26: time

<trackbot> Notes added to ISSUE-26 clarification of temporal vagueness requirement.

frans: ... these editors need to look at the use cases anyhow

<frans> ISSUE-28: BP

<trackbot> Notes added to ISSUE-28 That a default crs is a requirement.

<frans> ISSUE-29: BP

<trackbot> Notes added to ISSUE-29 Add a requirement for linking geometry to CRS.

<frans> ISSUE-30: BP

<trackbot> Notes added to ISSUE-30 UCR: missing requirement -- local/contextual spatial references.

frans: any comments on the proposal?

eparsons: a sensible way forward

frans: we could create actions for each deliverable / issue pair

kerry: sounds good

<scribe> ACTION: frans to create actions that matches UCR issues and deliverables [recorded in http://www.w3.org/2015/11/11-sdw-minutes.html#action01]

<trackbot> Created ACTION-93 - Create actions that matches ucr issues and deliverables [on Frans Knibbe - due 2015-11-18].

<eparsons> Thank you Frans !!!

kerry: anything else for UCR, frans?

frans: join the discussions

UCR: Issue-16 Time req. out of scope - Valid time

<kerry> http://www.w3.org/2015/spatial/track/issues/16

frans: special attention on ISSUE-16, is not related to a particular deliverable

<phila> issue-16?

<trackbot> issue-16 -- Time req. out of scope - Valid time -- open

<trackbot> http://www.w3.org/2015/spatial/track/issues/16

frans: should we discuss now?

<BartvanLeeuwen> +1

frans: problematic without Simon etc

(agreement to move to next week)

kerry: follow the list and let's try to get to a conclusion next week

<kerry> BP: Expanding best practice topics

BP: Expanding best practice topics

kerry: not much time until 9 December

Linda: in Sapporo most of the meeting was spent on BP
... ...discussion on narratives, took notes during discussion
... ...currently post-processing the notes to prepare topics that other could provide content or examples

<Linda> http://w3c.github.io/sdw/bp/#bp-linking

Linda: linking data is the first topic

<Linda> - How to make the links within a dataset discoverable

Linda: anyone who could provide input how to create good links, get the right granularity, etc?

BartvanLeeuwen: is working on a demo for bridging WFS and linked data
... Is that something that is relevant for this topic?

Linda: Yes

<BartvanLeeuwen> +1

<kerry> ACTION: bart to write about make the links within the dataset discoverable [recorded in http://www.w3.org/2015/11/11-sdw-minutes.html#action02]

<trackbot> Created ACTION-94 - Write about make the links within the dataset discoverable [on Bart van Leeuwen - due 2015-11-18].

<KJanowicz> Bart: wrt WFS and Linked Data, see http://carsten.io/jones-kuhn-kessler-scheider-agile2014.pdf (and other implementations)

kerry: clarification about the process? email ok or change Github directly?

Linda: Both fine, as long as we get the content

frans: what kind of links? all links or spatial links?

Linda: not specified, but should be related to spatial aspects, eg also links into spatial datasets

eparsons: could be linking to a thing or the spatial representation, there may be a difference

<BartvanLeeuwen> http://w3c.github.io/sdw/bp/#h-bp-clear-semantics

<phila> Yes, it was Linksets

<KJanowicz> +1

BartvanLeeuwen: need to clarify what's in scope, what's spatial

<BartvanLeeuwen> +1

<AndreaPerego> +1

eparsons: need to clarify that something without a geometry may be considered spatial and within scope of our work

<kerry> ACTION: linda to add to scope and link data section -- comment o spatail data without a geometry is in scope here [recorded in http://www.w3.org/2015/11/11-sdw-minutes.html#action03]

<trackbot> Created ACTION-95 - Add to scope and link data section -- comment o spatail data without a geometry is in scope here [on Linda van den Brink - due 2015-11-18].

Linda: will add this to the BP

frans: where one is coming from will influence how that topic is understood
... ...different audiences may require a different wording

<kerry> +1 to serve both groups of readers in same doc

Linda: not clear yet how to address this

<BartvanLeeuwen> +1 for one document

<eparsons> +1 to serve both may need to be more explicit as a result..

<Zakim> phila, you wanted to say reduce your assumptions

phila: agrees with frans
... one document, we just need to be clear and make no assumptions about prior knowledge

<frans> Or: make liberal use of the ability to link to definitions

<phila> <abbr title="World Wide Web Consortium">W3C</abbr>

phila: maybe use abbr mechanism in more cases

kerry: this is about more than just acronyms
... need to think how to present the different viewpoints, likely after 9 December

<Linda> - Making your spatial data more useful by including links to wellknown spatial resources (things like GeoNames, Wiki/dbPedia, OSM etc)

Linda: any volunteers for this topic?

billroberts: I can have a go at that

<kerry> ACTION: billroberts to write on make the links within the dataset discoverable [recorded in http://www.w3.org/2015/11/11-sdw-minutes.html#action04]

<trackbot> Error finding 'billroberts'. You can review and register nicknames at <http://www.w3.org/2015/spatial/track/users>.

<kerry> actio

<Linda> - Example of how you could link to a particular version of a thing

<phila> ACTION: roberts to write on make the links within the dataset discoverable [recorded in http://www.w3.org/2015/11/11-sdw-minutes.html#action05]

<trackbot> Created ACTION-96 - Write on make the links within the dataset discoverable [on Bill Roberts - due 2015-11-18].

Linda: any volunteers for this topic? in particular an example...

<BartvanLeeuwen> +q

frans: what is the spatial aspect?

eparsons: not particularly spatial, but occurs often with spatial data

frans: I experienced it more as a temporal than a spatial problem

<Zakim> phila, you wanted to talk about Annette Grainier

phila: discussed with DWBP group whether that group has subsetting use case that is not spatial
... will follow up on this to clarify relationship between groups

<kerry> ACTION: phila to work on subsetting links [recorded in http://www.w3.org/2015/11/11-sdw-minutes.html#action06]

<trackbot> Created ACTION-97 - Work on subsetting links [on Phil Archer - due 2015-11-18].

kerry: there is a topic in the DWBP, but high level - we probably need to go deeper

phila: either provide DWBP with better text or we add it in our own

kerry: probably in our own for now

billroberts: versioning should be in scope, but reference elsewhere and put it in a "spatial context" using an example

Linda: agrees, it should be an example

(discussion about whether a best practice on this topic already exists)

frans: how to match requirements

Linda: but should be done without loosing the narrative flow

<Linda> - A list/matrix of the common formats (GeoJSON, GML, RDF, JSON-LD) and what you can or can't achieve with it.

<frans> RDF is a format?

Linda: any volunteers?

phila: this will require input from more than one person and may trigger quite a bit of discussion

kerry: maybe a first attempt for now?

<KJanowicz> frans: not in a strict sense

<kerry> ACTION: clemens to look at A list/matrix of the common formats (GeoJSON, GML, RDF, JSON-LD) and what you can or can't achieve with it. [recorded in http://www.w3.org/2015/11/11-sdw-minutes.html#action07]

<trackbot> Created ACTION-98 - Look at a list/matrix of the common formats (geojson, gml, rdf, json-ld) and what you can or can't achieve with it. [on Clemens Portele - due 2015-11-18].

Reminder: next F2F Netherlands 8-10 Feb 2016

kerry: put Feb 8/9/10 in your calendar

<frans> 8th of february? Bring your ice skates

<phila> Looking forward to being in NL again

<KJanowicz> where exactly will the meeting take place?

<BartvanLeeuwen> Amersfoort

<frans> We have one hill, no mountains
