20:07:10 <eparsons> TOPIC: BP Decisions for wider consideration
20:07:34 <SimonCox> present+
20:08:07 <roba> jtandy: reviews summaries of BP discusses as per email
20:09:15 <eparsons> Proposal:  we shall we remove BP12 "Include search capability in your data

20:09:52 <DanhLePhuoc> +1
20:10:35 <roba> q+
20:11:04 <SimonCox> As long as there is a specific cross-reference ...
20:11:22 <eparsons> ack next
20:12:32 <eparsons> Proposal: we remove BP13 "Provide subsets for large spatial datasets"  because DWBP already says enough?

20:13:20 <ahaller2_> +1
20:13:39 <roba> roba: notes QB4ST work is based on RDF-QB which provides mechanisms to describe subset relationships to data sets, but that this hasnt been fully explored for spatial case, and its emergent practice anyway, not BP.
20:13:40 <roba> +1
20:13:55 <eparsons> Resolved:  we remove BP13 "Provide subsets for large spatial datasets"  because DWBP already says enough

20:14:30 <SimonCox_> present+
20:15:00 <roba> @SimonCox can you minute your point and the response - i was following up request to minute my own comment :-(
20:16:47 <SimonCox_> Wanted to clarify that for this issue (subsetting) since we are delgating the BP to DWBP, we must be sure to retain an explicit cross-reference in the SDWBP document - it is important to give the guidance even if the details are elsewhere
20:16:50 <eparsons> q?
20:19:13 <eparsons> Proposal: we remove BP2 "Provide context required to interpret data values"

20:19:42 <SimonCox_> My connection is clearly too slow
20:19:46 <eparsons> Resolved: we remove BP2 "Provide context required to interpret data values"
20:20:15 <SimonCox_> ahaller2_: that would be _envious_
20:20:31 <roba> @ahaller2_ only because we agree not to go there...

20:25:38 <eparsons> ack next
20:25:41 <ByronCinNZ> q+
20:26:25 <roba> kerry: agrees qualitative relationship is needed - samePlaceAs wont be an established BP
20:27:02 <roba> ... in common english "the same place" used, but dont carry geometry meanings
20:27:45 <ahaller2_> +1 to kerry
20:27:46 <eparsons> ack next
20:27:55 <roba> ...need to offer a solution - we have the power to solve this problem
20:28:22 <roba> ByronCinNZ: supporter of idea - not sure if its thought through enough...
20:29:03 <roba> ...get problematic quite quickly - cites example of hotel moved location.,,

20:29:42 <jtandy> q+

20:29:43 <roba> ...its an emergent issue

20:30:43 <kerry> +1 to ed
20:30:47 <roba> eparsons: "place" is different from "location" - and this is useful - can we park it and move on
20:31:59 <eparsons> ack next
20:32:14 <roba> jtandy: lots of people us owl:sameAs badly - "tis' would be "less wrong"
20:32:54 <roba> kerry: samePlaceAs has correct social context, colocation is specific about geometry and not what we need
20:33:28 <roba> jtandy: will draft something for F2F discussion
20:33:32 <eparsons> Action jtandy to add to F2F agenda discussions of this issue
20:33:33 <trackbot> Created ACTION-281 - Add to f2f agenda discussions of this issue [on Jeremy Tandy - due 2017-03-15].
20:33:50 <eparsons> TOPIC : Upcoming F2F in Delft agenda bashing part 2
20:34:51 <roba> ...monday is BP stuff only day jtandy can be present
20:35:47 <SimonCox> SimonCox has joined #sdw
20:36:19 <roba> jtandy: need to cover "open issues" - last sprint now! - all public comments need to be responded to
20:36:47 <roba> ...planning, review UC, samePlaceAs

20:41:04 <eparsons> 	Need to provide list by 15th march - https://www.w3.org/2015/spatial/wiki/Attending_F2F6
20:41:05 <SimonCox> Engagement on Time has been limited - I warned about level of effort that could be expected when I took on editing. CHris has done even less.
20:41:21 <eparsons> ack next
20:41:35 <SimonCox> Has mostly been done by email.
20:42:13 <eparsons> simon do you need time at the F2F ?
20:43:08 <eparsons> TOPIC: Namespace for SOSA and SSN ontology Part 2.
20:43:45 <ahaller2_> https://www.w3.org/2015/spatial/wiki/Integration_Issue
20:44:13 <roba> ahaller2_: took on board feedback - wiki page authored options - still in discussion - votes in wiki - f2F topic
20:44:51 <ahaller2_> Option 1: If you care about that every term has the same namespace, but don’t mind that the stronger axiomatisation of a term may not be directly accessible in a linked data fashion you will like Option 1.
20:45:31 <ahaller2_> Option 2: If you like Option 1 and would want direct access to every term in a linked data fashion, but don’t mind that terms that are precised in SSN will get an additional namespace, you like Option 2.
20:46:08 <eparsons> rrsagent, draft minutes
20:46:08 <RRSAgent> I have made the request to generate http://www.w3.org/2017/03/08-sdw-minutes.html eparsons
20:46:15 <ahaller2_> Option 3: If you care about the global consistency of terms on the Web, but don’t mind that some instances of SOSA are not valid SSN instances you will like Option 3.
20:47:05 <SimonCox_> SimonCox_ has joined #sdw
20:47:15 <SimonCox_> present+
20:47:27 <ahaller2_> Option 4: If you care about a common namespace for SSN and SOSA and being able to access terms directly in a Linked Data fashion, but don’t mind to have three namespaces, one of which is the common namespace that only introduces terms (their labels) you will like Option 4.
20:48:32 <ahaller2_> Option 5: If you care about the same reuse mechanism of terms as in Option 1, but don’t mind to have two namespaces and that the stronger axiomatisation of a term may not be directly accessible in a linked data fashion you will like Option 5.
20:49:09 <ahaller2_> Option 6: If you like Option 2 and care about direct access to terms in a linked data fashion, but don’t mind having a common namespace at all, you will like Option 6.
20:49:45 <roba> q+
20:49:56 <eparsons> ack next
20:50:05 <ahaller2_> Option 7: If you like Option 4, but don’t mind that the stronger axiomatisation of a term may not be directly accessible in a linked data fashion you will like Option 7.
20:50:49 <ahaller2_> Option 8: If you like Option 5 and you want to be able to access the stronger axiomatisation of a term in a linked data fashion, but don’t mind that SOSA imports an expressive OWL ontology, you will like Option 8.

20:55:30 <roba> roba: generally - number of options - because different concerns
20:55:44 <eparsons> kerry: doubts we have time for option 8

20:55:51 <eparsons> ack next
20:56:01 <roba> ...traversability
20:56:09 <roba> ...server requirements
20:56:48 <roba> kerry: option 8 looks good but worried it may be harder to realise in time frame

20:59:04 <roba> ...and indicate pref on wiki
20:59:46 <eparsons> TOPIC: Timezone changes for the last time !
21:00:21 <SimonCox_> Panicked for a moment then that you needed some work on timezones in OWL-Time
