20:00:40 <Ian_Holt> Should be
20:01:34 <MattPerry> Can I dial into a hangout with a phone?
20:01:37 <phila> I'm trying to listen to both conversations - nad it's already impossible
20:01:59 <eparsons> Matt no sorry online only
20:02:20 <FransK> FransK has joined #sdw2
20:03:27 <MattPerry> Ok. That's not going to work for my current location. I'll have to dial into the other group.
20:03:53 <phila> present+ Linda, Frans, Ed, Phil, Ian, Matt, Bart
20:04:44 <BartvanLeeuwen> zakim, pick a victim
20:04:44 <Zakim> sorry, BartvanLeeuwen, I don't know what conference this is
20:04:56 <MattPerry> Bye. I'm going to jump into the other one.
20:05:03 <phila> RRSAgent, make logs public
20:05:25 <Linda> scribe: Linda
20:05:33 <Linda> Ed: preliminarieds
20:06:09 <Linda> two housekeeping items:
20:06:27 <Linda> 1: email conversations should go via the public mailing list
20:06:41 <Linda> at least cc
20:07:31 <eparsons> http://www.w3.org/2015/11/TPAC/
20:07:32 <Linda> 2: we are planning the next face to face in Japan, W3C TPAC meeting.
20:07:47 <Linda> Try to get there
20:08:02 <stlemme> stlemme has joined #sdw2
20:08:03 <BartvanLeeuwen> q+
20:08:36 <eparsons> ack next
20:08:36 <BartvanLeeuwen> ack me
20:09:14 <Linda> Bart: when will it be definite that we have the f2f there? Because then I can book my plane ticket as prices are rising.
20:09:15 <phila> q+
20:09:25 <eparsons> ack next
20:09:27 <Linda> Ed: we'll make the decision in the next week or two.
20:10:10 <Linda> Phil: It will be either monday/tuesday or thursday/friday
20:10:27 <Linda> If you go to Sapporo, we'll ask you your preference
20:11:36 <eparsons> https://www.w3.org/2015/spatial/wiki/BP_Requirements
20:11:49 <Linda> Ed: we'll go quickly through the work we did at the f2f and then go on with the rest of the UC's
20:11:59 <Linda> thx phil
20:12:04 <eparsons> https://docs.google.com/spreadsheets/d/1PSnpJYQDgsdgZgPJEfUU0EhVfgFFYGc1WL4xUX9Dunk/edit#gid=1542305387
20:13:15 <Linda> ...created a spreadsheet with requirements. Will go through the list.
20:13:24 <Linda> Frans are you ok with that approach:
20:13:32 <Linda> Frans: ok
20:14:19 <Linda> eparsons: goes through the list
20:15:41 <eparsons> https://www.w3.org/2015/spatial/wiki/BP_Requirements
20:17:12 <Linda> ... what was the one on validation about?
20:17:33 <Linda> phila: having difficulty seeing what column we're at.
20:17:56 <phila> -> RDF Data Shapes WG https://www.w3.org/2014/data-shapes/wiki/Main_Page
20:18:00 <Linda> ... we have ways of validating xml, no standard for validating rdf. But the data shapes wg is working on it.
20:18:00 <phila> SHACL
20:18:30 <Linda> q+
20:18:47 <Linda> -q
20:19:03 <Linda> eparsons: we are also talking about whether the geometries are valid
20:19:14 <Linda> ... so two things: valid data and valid geometries
20:20:00 <Linda> ... the one about fuzziness is perhaps the most relevant and one we've been struggling about
20:20:02 <BartvanLeeuwen> q+
20:20:13 <eparsons> ack next
20:21:06 <Linda> BartvanLeeuwen: re hierarchical relations between locations: there could also be other spatial relations. Is that the same thing or a different topic
20:22:31 <Linda> ... administrative connections between features. Example: child care place on fire, need to place the kids in another daycare center.
20:22:47 <AndreaPerego> AndreaPerego has joined #sdw2
20:22:58 <Linda> ... maybe not the one closest by, but one that is close and also from the same organization.
20:23:29 <Linda> ... I could put another paragraph in my uc to clarify this.
20:23:57 <Linda> eparson: or add it to the requirements doc that Frans is editing.
20:24:30 <Linda> ... if you add the clarification, we'll capture it in the doc. It's a good requirement.
20:24:53 <eparsons> Hangout link at the top of the irc
20:25:22 <RRSAgent> I have made the request to generate http://www.w3.org/2015/03/25-sdw2-minutes.html phila
20:25:35 <Linda> eparsons: 3D geometry: just x,y,x or more complex than that?
20:25:58 <Linda> ... moving on to the reqs not specific to spatial data
20:26:09 <RRSAgent> I have made the request to generate http://www.w3.org/2015/03/25-sdw2-minutes.html phila
20:27:53 <Linda> eparsons: reqs around performance could be difficult
20:28:09 <Linda> ... we went through the first 25 or so use cases
20:28:33 <BartvanLeeuwen> +1
20:28:35 <Ian_Holt> +1
20:28:37 <Linda> ... I suggest we go through the rest of them now. Everybody clear about the process so far?
20:28:43 <Linda> +1
20:28:51 <AndreaPerego> +1
20:29:43 <Linda> ... Smart cities 101 use case
20:30:19 <Linda> ... a lot of information available at the links in the use case.
20:30:44 <Linda> ... digging through those links seems not helpful now.
20:31:06 <Linda> BartvanLeeuwen: it links to a 101 different use cases
20:31:20 <Linda> eparsons: next one. Linked data for tax assessment.
20:31:59 <AndreaPerego> q+
20:32:03 <Linda> ... provenance of data from authoritative sources
20:32:06 <eparsons> ack next
20:33:13 <Linda> AndreaPerego: a similar issue was discussed in barcelona.
20:33:47 <Linda> ed: yes I think it was discussed and I think we need to add it.
20:33:52 <AndreaPerego> See https://www.w3.org/2015/spatial/wiki/BP_Requirements#Be_able_to_annotate_data_with_a_specification_of_what_the_information_is_.2F_where_do_you_find_the_geographic_information_for_the_wellknown_reference_like_a_zip_code
20:34:21 <Linda> frans: provenance seems out of scope
20:34:40 <Linda> .... because it's not typically spatial
20:34:55 <Linda> eparsons: yes, I suppose. We can discuss that one.
20:35:41 <Linda> ... next one: Images, e.g. a Time series of a water course
20:35:47 <AndreaPerego> http://www.w3.org/2015/spatial/wiki/Working_Use_Cases#Images.2C_e.g._a_Time_series_of_a_Water_Course_.28Best_Practice.2C_Time.2C_SSN.2C_Coverage.29
20:36:11 <Linda> ... the idea of being able to capture time series of imagery.
20:36:18 <Linda> ... I think we did capture that
20:36:49 <Linda> ... next: droughts in geological complex environments.
20:36:52 <AndreaPerego> http://www.w3.org/2015/spatial/wiki/Working_Use_Cases#Droughts_in_geological_complex_environments_where_groundwater_is_important_.28Best_Practice.2C_Time.2C_SSN.2C_Coverage.29
20:37:50 <Linda> ... isn't this modeled environment instead of real world?
20:38:06 <AndreaPerego> q+
20:38:16 <eparsons> ack next
20:38:36 <Linda> AndreaPerego: not clear if this is about spatial data on the web
20:38:44 <Linda> eparsons: no, it's not clear.
20:39:19 <Linda> frans: there was a similar thing in the time group
20:39:27 <Linda> eparsons: we'll move on
20:39:41 <Linda> ... its not that clear to me, Chris can clarify if needed.
20:39:59 <AndreaPerego> Next UC: http://www.w3.org/2015/spatial/wiki/Working_Use_Cases#Soil_data_applications_.28Best_practice.2C_SSN.2C_Coverage.29
20:40:01 <Linda> ... next: Soil data. Anything specific here?
20:40:16 <Linda> ... noone argues, we'll move on
20:40:26 <Linda> ... next: bushfire response.
20:40:36 <AndreaPerego> http://www.w3.org/2015/spatial/wiki/Working_Use_Cases#Bushfire_response_coordination_centre_.28Best_practice.2C_SSN.29
20:41:05 <AndreaPerego> URI issue mentioned here.
20:41:08 <Linda> ... reads the list of interrelated use cases.
20:41:33 <Linda> ... not sure if there's anything new. Have we covered synonyms?
20:41:49 <Linda> Linda: I don't think so.
20:41:59 <Linda> eparsons: Frans? can you remember?
20:42:10 <AndreaPerego> q+
20:42:13 <Linda> frans: no, I can't think of one
20:42:23 <Linda> eparsons: so we'll need to add it.
20:43:28 <Linda> AndreaPerego: a related req is place names can change and people use unofficial names.
20:43:54 <Linda> ... not sure if we can merge these all together. Maybe should be separate, but are related.
20:44:15 <AndreaPerego> See: https://www.w3.org/2015/spatial/wiki/BP_Requirements#Named_places_can_overlap_and_change_over_time
20:44:39 <Linda> eparsons: definitely a key requirement
20:44:54 <Linda> frans: all data on the web can change
20:45:35 <Linda> eparsons: true, but there are issues that are more complex. Like colloquial geography.
20:46:28 <Linda> Linda: important for cultural heritage use cases
20:47:00 <Linda> frans: i remember Chaals made a point of scoping the requirements because we should be careful not to have too much work.
20:47:08 <BartvanLeeuwen> +1
20:47:13 <Linda> ... and this is not typically spatial, so out of scope.
20:47:22 <AndreaPerego> Not sure...
20:47:46 <Ian_Holt> +1 Andrea
20:48:06 <Linda> eparsons: maybe discuss this offline / via email. Maybe not typically spatial but there is a spatial element to the problem. Not convinced we can drop this. Discuss via email.
20:48:16 <AndreaPerego> More discussion needed indeed.
20:48:24 <Linda> ... will try to come up with a convincing example.
20:48:41 <Linda> ... next: observation of geological samples
20:49:08 <Linda> ... nothing use here except things for the other group
20:49:24 <Linda> BartvanLeeuwen: my comment was about the previous question.
20:49:37 <Linda> eparsons: next: spatial sampling, Covered by the other group.
20:50:09 <Linda> ... next: Select hierarchical geographical regions. Again the hierarchy req we were discussing.
20:50:40 <AndreaPerego> http://www.w3.org/2015/spatial/wiki/Working_Use_Cases#Select_hierarchical_geographical_regions_for_use_in_data_analysis_or_visualisation_.28Best_practices.2C_Time.2C_Coverage.29
20:50:52 <Linda> ... the changing over time thing comes up in this uc.
20:51:37 <Linda> ... next one :satellite data processing. More for the other group.
20:51:40 <AndreaPerego> http://www.w3.org/2015/spatial/wiki/Working_Use_Cases#Satellite_data_processing_.28Best_practice.2C_SSN.2C_Coverage.29
20:51:45 <Linda> ... the ones on marine observations as well.
20:52:25 <Linda> ... next: BIM. anything new here Linda?
20:52:38 <Linda> Linda: no, everything covered
20:52:47 <Linda> eparsons: next: landsat data services
20:53:22 <AndreaPerego> http://www.w3.org/2015/spatial/wiki/Working_Use_Cases#Metadata_and_Search_Granularity_.28Best_Practice.2C_Time.29
20:53:23 <AndreaPerego> q+
20:53:39 <Linda> ... related to level of granularity and URIs. Nothing new, anyone? ?
20:54:25 <Linda> AndreaPerego: how to make available spatial data that may be not easily consumable by web applications.
20:54:52 <Linda> ... depending on granularity you can have huge files.
20:55:24 <Linda> ... a req could be to describe the data in the metadata
20:55:49 <Linda> ... the use case should be described more clearly
20:56:26 <Linda> eparsons: are you talking about something in the middle between metadata and very finegrained data.
20:56:37 <Linda> AndreaPerego: yes, exactly.
20:56:46 <Linda> eparsons: is this a new requirement?
20:56:56 <Linda> ... lets put this on the email
20:57:12 <AndreaPerego> +1
20:57:55 <Linda> ... not going to rush through the rest of the uc's. Next week: start with Crowd sourced earthquake observation information, nr 42.
20:57:58 <AndreaPerego> http://www.w3.org/2015/spatial/wiki/Working_Use_Cases#Crowd_sourced_earthquake_observation_information_.28Best_Practice.2CSSN.29
20:58:14 <Linda> ... and will have at least a couple of email discussions.
