This was one of two parallel meetings held so that the WG could divide its work up most efficiently. This one focused on the requirements relevent to the Best Practices document, the other focused on the other deliverables.

approve minutes from last week

JoshLieberman: Mention on fine grained metadata - can you expand?

eparsons: How much would we need to beyond what was happening on the web in general...

JoshLieberman: could be about resolution and other metadata related to spatial aspects

eparsons: Need to revisit this when we get back to the requirements

<JoshLieberman> Was just about to ask that! Spatial is often out ahead...

<AndreaPerego> Can you hear me?

<Linda> no we cant'

<AndreaPerego> yep

<JoshLieberman> Getting some ...breathing on the line.

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

<Linda> +1

<eparsons> +1

<phila> RESOLVED: Last week's minutes accepted http://www.w3.org/2015/03/25-sdw2-minutes.html

<phila> http://www.w3.org/2015/spatial/track/actions/open

<AndreaPerego> https://www.w3.org/2015/spatial/wiki/Minutes_from_Best_Practice_deliverable_group#Summary_of_Action_Items

AndreaPerego: Open actions in the Barcelona meetings, but not in the tracker (on Chaals and Clemens)

Discussion of use cases

<eparsons> https://docs.google.com/spreadsheets/d/1PSnpJYQDgsdgZgPJEfUU0EhVfgFFYGc1WL4xUX9Dunk/edit#gid=1542305387

UC 42 Crowd sourced earthquake observation information

<eparsons> https://www.w3.org/2015/spatial/wiki/Working_Use_Cases#Crowd_sourced_earthquake_observation_information_.28Best_Practice.2CSSN.29

eparsons: requires spatial ontology and URIs
... metadata, too
... api not really discussing dissemination of the data

JoshLieberman: provenance is important, too

phila: not going to put into the docs that you should enable geo-location when tweeting about an earthquake

JoshLieberman: do virtual observations apply to this?

eparsons: is that a requirement that is in the use case or are we extending it?

UC 43 Microscopy Imaging

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?

JoshLieberman: Key is that this is not about a geo-centric reference system

<AndreaPerego> Maybe it's just about describing the "shape" of an entity, and not to locate it.

eparsons: current requirement about ref system not sufficient to capture the "metaphysical" aspects

<scribe> ACTION: Josh to come up with a sentence that captures the UC 43 discussion [recorded in http://www.w3.org/2015/04/01-sdw2-minutes.html#action01]

<trackbot> Sorry, but no Tracker is associated with this channel.

phila: time aspect in this use case?

<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

phila: Probably the other group will deal with this (Erich is there, too)

Discussion about the term "authoritative reference". Maybe change to "global reference"?

<AndreaPerego> +1

UC 44 Crop yield estimation

eparsons: from a best practice point of view, not new is apparent

UC 45 Geospatial extensions to domain-independent metadata schemas

<eparsons> ok thx phil

AndreaPerego: extension to general metadata standards in Europe (for geospatial and statistical data); touches several of the topics discussed before - CRS, geometries, ...
... Also data quality (not necessarily specific to spatial)
... probably no new requirements, just supporting the need for a couple already identified
... 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?

<Zakim> phila, you wanted to talk about data quality and URI design

<phila> DCAT

phila: would be good if this group could provide input to work on extensions to DCAT for spatial

<phila> Recommendations on the use of HTTP URIs for geospatial data and metadata

JoshLieberman: lots of work on metadata, many standard; also depends on the viewpoint what is called metadata
... best practice should focus on simple things (e.g., how to find bounding box when following a link)

UC 46 Improving discovery of spatial data on the web

AndreaPerego: How to make spatial data more discoverable using general search engines? Use of HTML, RDFa, microdata, etc

<phila> Columns F & J are relevant here

eparsons: related to other use case, but less about recommendation when creating new resources, more about enabling existing resources

AndreaPerego: Not necessarily restricted to search engines, could also be other web applications

JoshLieberman: related to RESTful APIs?
... in the sense of landing pages

<stlemme> in fact there are four UCs

<stlemme> in fact there are four UCs remaining

eparsons: send comments on the other use cases via email
... next week single meeting again
... face-to-face meeting will be at TPAC in Japan

phila: either Mon/Tue or Thu/Fri

Linda: When will this be decided?

phila: will work with chairs on this

<phila> TPAC 2015 venue
