20:17:07 <marqh> Dennis: statistics netherlands architect.  open data service started 3 years ago.  lacking data set interoperability.
20:17:24 <marqh> ... interest in how we can provide more interoperability
20:17:32 <AndreaPerego> s/research centre/Joint Research Centre of the European Commission/
20:17:42 <marqh> ... not sure how to do this with data cubes now

20:19:07 <marqh> ... exploring linked data to use more generally
20:19:28 <marqh> ... keen to learn how other people have done things
20:20:13 <marqh> kalampokis: involved in european union projects: linked open statistical data, using rdf data cubes

20:23:10 <AndreaPerego> Nope.
20:23:12 <marqh> microphone issues :$
20:23:18 <marqh> i'll type a quick intro for you
20:23:31 <marqh> marqh: work at met office, colleague of chris Little
20:23:48 <marqh> ... interested in how to encode statistcal post processing data sets
20:23:56 <marqh> ... their metadata gets complicated
20:24:04 <marqh> ... enough :)
20:24:49 <AndreaPerego> s/password sdwig//
20:24:59 <marqh> MichaelGordon: work at Ordnance survey UK, work with public sector.  combining geospatial data for policy outcomes
20:26:01 <marqh> ... interested in use cases.  worked with office of national statistics UK
20:26:24 <marqh> billroberts: do you know if Claire is intested in participating in this work
20:26:35 <marqh> MichaelGordon: I think she is
20:27:25 <marqh> billroberts: suggestions for how to organise our work.  this is largely copying the way we worked on sdwwg
20:27:32 <billroberts> 1. Use Cases
20:27:38 <billroberts> 2. Examples of good practice
20:27:55 <billroberts> 3. Requirement
20:28:02 <billroberts> 4. Best practices
20:28:18 <billroberts> https://www.w3.org/TR/sdw-bp/ and https://www.w3.org/TR/dwbp/
20:28:42 <marqh> billroberts: links are to best practice document lists from recent groups
20:28:57 <billroberts> https://www.w3.org/TR/sdw-ucr/
20:29:43 <billroberts> https://github.com/w3c/sdw/tree/gh-pages/stats-bp
20:29:53 <marqh> billroberts: I suggest we follow a similar style.  I would like people to make a start on use cases and requirements
20:30:18 <marqh> ... we may need help with permissions set up
20:30:38 <marqh> if you weren't in sdwwg, you may not have rights to write
20:30:45 <billroberts> fd@w3.org
20:31:11 <marqh> billroberts: in terms of mechanics, I am happy for people to edit directly into these documents
20:31:31 <marqh> ... happy to pick things up from mailing list
20:31:38 <AndreaPerego> q+ to point at the UCR template of DXWG as a possible alternative to the SDW one
20:32:05 <marqh> billroberts: over the next couple of weeks, if everyone can start volunteering use cases
20:32:24 <marqh> ... good and interesting ways people have gone about sharing statistical data through the web
20:32:33 <marqh> ... don't be shy about posting your own work
20:32:53 <billroberts> q?
20:33:07 <marqh> ChrisLittle: I would like to highlight problem areas: interested in scope
20:33:34 <marqh> ... many years ago, we used controlled vocabularies: pressure, humidity; lots of statistics for these parameters
20:33:50 <marqh> ... want property language, or attribute language or statistical language
20:34:09 <marqh> ... have parameter names, and statistics list; avoid combinatorial explosion
20:34:30 <marqh> ... vocabulary, ontology? of major statistical parameters.  Do you think that is in scope?
20:35:02 <marqh> ... deliverable for OGC Met Ocean domain working group.  we have statisticains on board now
20:35:09 <Dennis> i think its in scope
20:35:18 <marqh> billroberts: I think this is interesting, it sounds like it is in scope
20:36:12 <marqh> ChrisLittle: domain over which statistics are calculated, such as time.  When RDF data Cube was defined, dimensions and slices over complex time periods is hard; has not been well tackled
20:36:35 <marqh> ... complex language, tied up with calendars and coordinate reference systems.  is this pushing the boundaries of scope to far
20:36:52 <marqh> billroberts: to some extent, if participants think something is in scope it is in scope
20:37:01 <marqh> ... things may need to be prioritised later
20:37:20 <billroberts> ack a
20:37:20 <Zakim> AndreaPerego, you wanted to point at the UCR template of DXWG as a possible alternative to the SDW one
20:37:49 <AndreaPerego> DXWG UCR (working draft): https://w3c.github.io/dxwg/ucr/
20:37:55 <marqh> AndreaPerego: other group is active, don't know if you are aware of this group (link)
20:37:56 <AndreaPerego> An example: https://w3c.github.io/dxwg/ucr/#ID20
20:39:03 <marqh> AndreaPerego: structure, including description.  has use cases, which could be mapped.  in github ther is a template for capturing issues, within the issue tracker
20:39:21 <marqh> ... we are looking at the use of DCAT, this could be relevant
20:39:47 <marqh> ... this group should be aware of the work going on in other related activities
20:40:05 <AndreaPerego> DXWG charter: https://www.w3.org/2017/dxwg/charter
20:40:15 <marqh> billroberts: is that's the stats dcat application profile group?
20:40:24 <marqh> AndreaPerego: no, this is on their github site
20:40:48 <marqh> billroberts: it would be good to liaise with those people
20:41:00 <marqh> ... we don't want to be reinventing things
20:41:28 <marqh> ... On the use case template: this would add some structure, without looking like it would be difficult to use
20:41:42 <marqh> ... I'd encourage people to add those section if people have the informaiton available
20:41:52 <marqh> s/informaiton/information
20:42:04 <marqh> AndreaPerego: the group likes to have evidence about the requirements and use cases
20:42:54 <marqh> billroberts: are there more comments on chris's questions about scope? or other questions about use cases?
20:43:40 <marqh> ... initially, writing things down will help.  It would be good to add a use case and an example
20:43:57 <marqh> ... each
20:44:32 <marqh> billroberts: roba welcome. have done round of introductions
20:44:49 <marqh> roba: I am here on behalf of OGC, working on next geos project
20:45:02 <marqh> ... systems mostly have some geostatistical issues
20:45:17 <marqh> ... sometimes aggregations, or integral
20:45:32 <marqh> ... worked on sdwwg on qb4st and sdmx, for underlying metamodel
20:45:41 <billroberts> present+ roba
20:45:56 <marqh> ... this W3 note, I am eager to support evolution of this, if it turns out to be useful
20:46:23 <marqh> billroberts: this is an interesting one: extends statistics into aspects of the coverage domain
20:46:58 <marqh> ... I am encouraging people to write down initial use cases, and note down examples of good practice
20:47:13 <marqh> ... links in meeting notes
20:47:43 <AndreaPerego> AndreaPerego has joined #sdw
20:47:46 <marqh> roba: a lot of sdwwg work was on coverages.  sdmx is more about statistical areas.  some of principles of qbst set out
20:48:05 <marqh> ... need to explore how it links to dggs and register of spatial standards
20:48:16 <marqh> ... more work to be done to look at practical realisation
20:48:25 <AndreaPerego> s/qbst/QB4ST/
20:48:29 <marqh> ... getting to the stage of implementation experience

20:50:39 <marqh> billroberts: final contributions?
20:50:56 <marqh> billroberts: please everyone make a start on use cases and examples
20:51:45 <josephabhayaratna> no, works well
20:51:48 <marqh> billroberts: for fixing on next meeting: is this a good time for Europeans, Australians, Americans.  are ther objections to sticking with 2000 UTC time slot

20:54:21 <AndreaPerego> I won't be there, but I can try and join remotely
20:54:36 <marqh> marqh: Is the aim for this group to meet fortnightly?
20:55:22 <marqh> billroberts: suggest we meet at this time in 2 weeks, then get a report in a onth's time

20:55:44 <marqh> roba: I would like to announce this group to the OGC Geosemantics working group
20:55:56 <marqh> billroberts: marqh: yes aim for fortnightly meetings
20:55:57 <billroberts> ack j
20:56:26 <marqh> josephabhayaratna: geosemantics sent me an email this morning.  they don't have a ton on their agenda, could we have this meeting within the geosemantics DWG
20:56:56 <marqh> ... at same time as this meeting is scheduled
20:58:04 <marqh> josephabhayaratna: OGC meeting may connect via gotomeeting, not webex
20:59:06 <marqh> ... would need a good plan for the meeting, present scope, invite comments
20:59:44 <marqh> ... could someone put together a slide pack with who we are and scope?
21:00:30 <marqh> josephabhayaratna: i'll send template, we can put together information via call or email
