13:08:40 <SimonCox> eparsons: Issue013
13:09:27 <SimonCox> Alejandro: ISSUE 13 Profiling
13:10:29 <SimonCox> Alejandro: Profiles of SSN 1. constrained model 2. compliance - unclear which?
13:12:42 <SimonCox> Alejandro: understands need to check data is compliant with SSN model - no clear way to do this - W3C RDF Data Shapes probably relevant but incomplete
13:12:51 <Payam> forgot how to add myself to the qeue

13:13:17 <ahaller2> q+
13:14:10 <eparsons> q?
13:14:36 <SimonCox> Alejandro: e.g. geology wants to define version of SSN with specific constraints on values - probably not possible in SDW - must be delegated to application community?

13:16:15 <SimonCox> Payam: validation is needed in Requirements
13:16:54 <SimonCox> Chris is a chipmunk
13:16:55 <Alejandro_Llaves> helium?
13:17:11 <SimonCox> Come down Chris - all forgiven
13:17:41 <SimonCox> General hilarity
13:18:22 <Zakim> Zakim has joined #sdw
13:18:51 <eparsons> q+
13:18:54 <SimonCox> Armin: 1. RDF Shapes not viable solution 2. different modules of SSNO makes it difficult to define generic validation service
13:18:56 <eparsons> q-
13:19:03 <jtandy> q+
13:19:52 <SimonCox> Chris: if SSNO is complex, profiles are essential; if SSNO is simple, profiles implies SSNO is inadequate - which?
13:19:57 <eparsons> ack next
13:20:34 <SimonCox> Jeremy: SSNO is complex; typically necessary to add domain specific aspects in a profile
13:21:10 <Alejandro_Llaves> +q
13:21:31 <SimonCox> Jeremy: RDF Data Shapes is unlikely to be finished in time
13:22:18 <eparsons> ack next
13:22:29 <ChrisLittle> +1 jeremy
13:22:48 <SimonCox> Jeremy: Is simplifying a complex model for a domain application a 'best practice' in its own right?
13:23:15 <jtandy> q+
13:23:27 <SimonCox> Alejandro: do we agree SSNO validator required?
13:23:41 <ahaller2> +1 profile
13:23:45 <ahaller2> -1 validator
13:23:48 <SimonCox> Alejandro: do we need SSNO profiles?
13:23:51 <eparsons> ack next
13:24:43 <SimonCox> Jeremy: is the validator/profile requirement specific to SSNO? Or is this a generic requirement - to be able to profile/validate against data models?
13:25:34 <SimonCox> Alejandro: focussing on what goes in document
13:26:22 <ahaller2> q+
13:26:30 <eparsons> ack next
13:26:36 <SimonCox> Alejandro: set 'solutions' aside at this time?
13:27:03 <SimonCox> Armin: what does validator actually validate?
13:27:36 <Payam> +q
13:27:44 <eparsons> ack next
13:28:13 <SimonCox> Payam: validation allows combination of more than one ontology
13:28:37 <jtandy> q+
13:28:42 <Payam> ack Payam
13:28:45 <eparsons> ack next
13:28:56 <aharth> q+ there is no validator for ontologies
13:29:02 <aharth> q+
13:29:18 <SimonCox> Jeremy: 1. validation = verify that data is complete, to support application
13:29:39 <AndreaPerego> AndreaPerego has joined #sdw
13:29:42 <SimonCox> Jeremy: 2. validation = verify that profile is conformant to general case
13:30:02 <eparsons> ack next
13:30:39 <SimonCox> Andreas: OWL models/ontologies are concerned with logical consistency, not integrity
13:31:57 <SimonCox> ANdreas: RDF data shapes - add integrity checks; QB includes SPARQL ASK queries to check integrity
13:32:30 <SimonCox> Ed: not convinced there is big validation requirement
13:33:30 <ahaller2> don't care
13:33:39 <SimonCox> Alejandro: Barcelona discussion focussed on validation; requirements on list/document appears to focus more on application-specific profiles
13:33:43 <aharth> link to qb well-formed section: http://www.w3.org/TR/vocab-data-cube/#wf
13:33:47 <ahaller2> it is the web, everyone can extend ontologies how they like
13:34:12 <SimonCox> Ed: requirement does not call out validation - can we close issue?
13:34:47 <AndreaPerego> present+ AndreaPerego
13:34:56 <SimonCox> Jeremy: ask validation question in UCR nexct draft?
13:35:09 <Payam> I'm sorry, I have to leave early today
13:35:23 <eparsons> PROPOSED: Close issue - case for validation not made yet.. will revisit

13:35:47 <SimonCox> Ed: close ISSUE 13 - no case for validation yet (can be reopened later)
13:35:50 <MattPerry> +1
13:36:28 <eparsons> RESOLVED: Close issue - case for validation not made yet.. will revisit
13:36:34 <SimonCox> Jeremy: call out 'candidate' and 'deferred' requirements - validation = candidate requirement, not addressed now
13:36:52 <jtandy> Candidate ... Accepted ... Deferred requirements ...
13:37:07 <jtandy> (see http://w3c.github.io/csvw/use-cases-and-requirements/index.html for example)
13:37:40 <SimonCox> Jeremy: use precedent from CSV on web
13:37:47 <eparsons> Topic : Best Practice Consolidation Progress
13:37:56 <SimonCox> Ed: next - BP til now
13:38:19 <Alejandro_Llaves> I did not
13:38:27 <Alejandro_Llaves> https://www.w3.org/2015/spatial/wiki/BP_Consolidation
13:39:15 <SimonCox> Jeremy: has membership reviewed https://www.w3.org/2015/spatial/wiki/BP_Consolidation ?
13:39:52 <SimonCox> Jeremy: propose working through UCs to pull out common themes to use in narrative?
13:40:49 <eparsons> +1
13:41:01 <SimonCox> Jeremy: focus is on Spatial Best Practices in general, Time/overages/SSN only incidentally
13:41:02 <Alejandro_Llaves> +1
13:41:06 <LarsG> +1
13:41:15 <SimonCox> s/overages/coverages/
13:42:06 <SimonCox> Jeremy: publisher vs consumer view - typically publisher wears cost to make consumer's life easier.
13:43:35 <SimonCox> Jeremy: see summary https://www.w3.org/2015/spatial/wiki/BP_Consolidation#Analysis_pointers
13:45:03 <SimonCox> Jeremy: e.g. looking for wildfires using satellite imagery - UC is mostly about classifying pixels; BP can't address details of processing algorithms, but might look at BP relating to inputs and outputs
13:45:38 <SimonCox> Ed: yes, separate concerns
13:45:45 <AndreaPerego> q+
13:45:55 <eparsons> ack next
13:46:09 <SimonCox> Jeremy: workflows out of scope
13:46:40 <SimonCox> Andrea: why focus on UCs rather than requirements?
13:47:06 <SimonCox> Andrea: appears to refine UCR rather than move towards BPs
13:48:17 <SimonCox> Jeremy: rationale = arrange BP around narrative stories, i.e. UCs
13:48:52 <SimonCox> Jeremy: will ensure that BP does address real stories
13:49:37 <SimonCox> Jeremy: compress 48 UCs into a small number of narrative stories
13:50:03 <Alejandro_Llaves> sounds good to me!
13:50:22 <AndreaPerego> +1 from em
13:50:36 <AndreaPerego> s/from em/from me/
13:51:10 <SimonCox> Jeremy: consolidation and mapping requirements to stories allows us to check completeness

13:52:45 <chaals> chaals has joined #sdw
13:53:25 <SimonCox> Jeremy: BP will not recommend encodings?
13:54:02 <SimonCox> Ed: this would be a big gap, risks making the BP not meet expectations?
13:54:43 <SimonCox> Ed, Jeremy: provide examples, but not exclusive list - make it clear that other techniques would be possible.
13:54:45 <ChrisLittle> q+
13:55:08 <eparsons> ack next
13:55:18 <SimonCox> Ed: BP should be as complete as possible; self-contained as far as possible
13:55:46 <SimonCox> Chris: BP should include list of formats, with comments on pros and cons of each format
13:56:30 <SimonCox> Ed: how long will it take to consolidate themes? How many?
13:57:08 <ChrisLittle> suggest 6 rather than 12 narratives
13:57:17 <SimonCox> Jeremy: no more than 12; BP document must be short-enough ... ; 1-11 took 3 hours, 12-48 to go
13:58:07 <eparsons> Topic: ANOB
13:58:24 <SimonCox> Ed: use discussion tab on https://www.w3.org/2015/spatial/wiki/BP_Consolidation
13:58:32 <AndreaPerego> Around 10 would be reasonable - 6 are probably not enough to cover all the relevant use cases.
13:58:33 <SimonCox> Book travel to Sapporo asap
13:58:52 <SimonCox> No direct flights to Sapporo
13:59:15 <SimonCox> Best prices are via Tokyo
