20:05:18 <ClemensPortele> TOPIC: approve minutes from last week
20:05:55 <ClemensPortele> JoshLieberman: Mention on fine grained metadata - can you expand?
20:06:31 <ClemensPortele> Ed: How much would we need to beyond what was happening on the web in general...
20:07:21 <ClemensPortele> JoshLieberman: could be about resolution and other metadata related to spatial aspects
20:07:33 <ClemensPortele> s/Ed/eparsons/
20:08:15 <ClemensPortele> eparsons: Need to revisit this when we get back to the requirements
20:08:33 <JoshLieberman> Was just about to ask that! Spatial is often out ahead...

20:09:19 <AndreaPerego> Can you hear me?
20:09:25 <Linda> no we cant'
20:09:32 <AndreaPerego> yep
20:10:11 <JoshLieberman> Getting some ...breathing on the line.
20:10:58 <ClemensPortele> AndreaPerego: regarding requirements not just related to spatial and which are more general - we may need to do something specific in spatial with general concepts; URIs may be an example

20:11:34 <phila> RESOLVED: Last week's minutes accepted http://www.w3.org/2015/03/25-sdw2-minutes.html
20:12:31 <phila> http://www.w3.org/2015/spatial/track/actions/open
20:12:38 <AndreaPerego> https://www.w3.org/2015/spatial/wiki/Minutes_from_Best_Practice_deliverable_group#Summary_of_Action_Items
20:13:11 <ClemensPortele> AndreaPerego: Open actions in the Barcelona meetings, but not in the tracker (on Chaals and Clemens)
20:14:36 <ClemensPortele> TOPIC: Discussion of use cases
20:15:01 <eparsons> https://docs.google.com/spreadsheets/d/1PSnpJYQDgsdgZgPJEfUU0EhVfgFFYGc1WL4xUX9Dunk/edit#gid=1542305387
20:15:44 <ClemensPortele> TOPIC: UC 42 Crowd sourced earthquake observation information
20:15:48 <eparsons> https://www.w3.org/2015/spatial/wiki/Working_Use_Cases#Crowd_sourced_earthquake_observation_information_.28Best_Practice.2CSSN.29
20:16:41 <ClemensPortele> eparsons: requires spatial ontology and URIs
20:17:36 <ClemensPortele> eparsons: metadata, too
20:17:41 <ClemensPortele> eparsons: api not really discussing dissemination of the data
20:18:40 <ClemensPortele> JoshLieberman: provenance is important, too
20:19:52 <ClemensPortele> phila: not going to put into the docs that you should enable geo-location when tweeting about an earthquake
20:20:27 <AndreaPerego> Let's move one
20:20:39 <AndreaPerego> s/Let's move one//
20:20:51 <ClemensPortele> JoshLieberman: do virtual observations apply to this?
20:22:37 <ClemensPortele> eparsons: is that a requirement that is in the use case or are we extending it?
20:22:58 <phila> present+ Andrea, Clemens, Ed, Josh, Linda, Matt, Phil, stlemme
20:23:29 <ClemensPortele> TOPIC: UC 43 Microscopy Imaging
20:24:48 <ClemensPortele> eparsons: an issue of scale, more than anything else. Is that really different that we need to address or do we just to be clear not to be scale-specific?
20:25:37 <ClemensPortele> JoshLieberman: Key is that this is not about a geo-centric reference system
20:27:20 <AndreaPerego> Maybe it's just about describing the "shape" of an entity, and not to locate it.
20:28:03 <ClemensPortele> eparsons: current requirement about ref system not sufficient to capture the "metaphysical" aspects
20:30:14 <ClemensPortele> ACTION: Josh to come up with a sentence that captures the UC 43 discussion
20:30:14 <trackbot> Sorry, but no Tracker is associated with this channel.
20:30:55 <ClemensPortele> phila: time aspect in this use case?
20:31:15 <JoshLieberman> Requires not just a coordinate reference system but also an authoritative reference to the space or object that data is being positioned within / upon
20:31:32 <ClemensPortele> phila: Probably the other group will deal with this (Eric is there, too)
20:31:49 <phila> s/Eric/Erich/
20:33:18 <ClemensPortele> Discussion about the term "authoritative reference". Maybe change to "global reference"?
20:34:03 <AndreaPerego> +1
20:34:38 <ClemensPortele> TOPIC: UC 44 Crop yield estimation
20:35:31 <ClemensPortele> eparsons: from a best practice point of view, not new is apparent
20:36:07 <ClemensPortele> TOPIC: UC 45 Geospatial extensions to domain-independent metadata schemas
20:37:18 <eparsons> ok thx phil
20:39:09 <ClemensPortele> AndreaPerego: extension to general metadata standards in Europe (for geospatial and statistical data); touches several of the topics discussed before - CRS, geometries, ...
20:39:27 <phila> q+ to talk about data quality and URI design
20:39:53 <ClemensPortele> AndreaPerego: Also data quality (not necessarily specific to spatial)
20:40:49 <ClemensPortele> AndreaPerego: probably no new requirements, just supporting the need for a couple already identified
20:42:00 <ClemensPortele> AndreaPerego: However, one question is how to model something in a non-domain-specific way (level of detail vs spatial resolution); what are the design patterns for this?
20:42:08 <eparsons> ack next
20:42:09 <Zakim> phila, you wanted to talk about data quality and URI design
20:42:37 <phila> -> http://www.w3.org/TR/vocab-dcat/ DCAT
20:43:34 <phila> q-
20:43:55 <ClemensPortele> phila: would be good if this group could provide input to work on extensions to DCAT for spatial
20:44:32 <Linda> q+
20:45:01 <phila> Recommendations on the use of HTTP URIs for geospatial data and metadata
20:45:22 <Linda> q-
20:45:50 <JoshLieberman> q+
20:47:08 <eparsons> ack next
20:48:30 <ClemensPortele> JoshLieberman: lots of work on metadata, many standard; also depends on the viewpoint what is called metadata
20:49:22 <ClemensPortele> JoshLieberman: best practice should focus on simple things (e.g., how to find bounding box when following a link)
20:51:31 <ClemensPortele> TOPIC: UC 46 Improving discovery of spatial data on the web
20:53:08 <ClemensPortele> AndreaPerego: How to make spatial data more discoverable using general search engines? Use of HTML, RDFa, microdata, etc
20:53:54 <phila> Columns F & J are relevant here
20:54:04 <ClemensPortele> eparsons: related to other use case, but less about recommendation when creating new resources, more about enabling existing resources
20:54:43 <ClemensPortele> AndreaPerego: Not necessarily restricted to search engines, could also be other web applications
20:55:52 <ClemensPortele> JoshLieberman: related to RESTful APIs?
20:56:48 <ClemensPortele> JoshLieberman: in the sense of landing pages
20:58:08 <stlemme> in fact there are four UCs
20:58:19 <stlemme> in fact there are four UCs remaining
20:58:36 <ClemensPortele> eparsons: send comments on the other use cases via email
20:58:43 <ClemensPortele> eparsons: next week single meeting again
20:59:03 <ClemensPortele> eparsons: face-to-face meeting will be at TPAC in Japan
20:59:20 <ClemensPortele> phila: either Mon/Tue or Thu/Fri
20:59:40 <ClemensPortele> Linda: When will this be decided?
21:00:19 <ClemensPortele> phila: will work with chairs on this
21:00:27 <phila> -> http://www.sora-scc.jp/eng/index.html TPAC 2015 venue
