   … working group suggested specific follow on work
   … statistics on the web: target 'best practice'

   billroberts: aim to complete half way through 2019


   billroberts: my interest arose from sdwwg work. day to day work
   with statistical data, using rdf data cube
   … work for swirl, a UK company working often with government to
   publish statistical data
   … would like to: work with all of you; find good ways to tackle
   problems, document best practice

   AndreaPerego: Joint Research Centre of the European Commission,
   involved in setting up European infrastructure for
   environmental data (INSPIRE), including statistical data
   … geospatial and statistical data availability
   … focus on interoperability for spatial and statistical data
   … contributed to spatial data on the web best practices

   ChrisLittle: Met Office, sit on SVCG working group in OGC and
   founded metOcean OGC group and work on OGC architecture board
   … interest in graphics, I have interesting use cases for

   Dennis: statistics netherlands architect. open data service
   started 3 years ago. lacking data set interoperability.
   … interest in how we can provide more interoperability
   … not sure how to do this with data cubes now

   josephabhayaratna: Australian company (PSMA Australia), have
   stong relationship with Australian Bureau of statistics,
   publishing linked data
   … australian statistics geographic standard. we are helping
   them to publish
   … exploring linked data to use more generally
   … keen to learn how other people have done things

   kalampokis: involved in european union projects: linked open
   statistical data, using rdf data cubes
   … interested in exploring how end users can exploit linked data
   … collaborated with SME and public administration
   … applying rdf data cube standard. need to create best
   practices to accomodate all these standards

   kalampokis: member of semantic statistics community group

   kalampokis: i am a joint point of contact for these groups

   <AndreaPerego> Nope.

   <marqh> Microphone issues :$

   <marqh> I'll type a quick intro for you

   marqh: work at met office, colleague of chris Little
   … interested in how to encode statistical post processing data
   … their metadata gets complicated
   … enough :)

   MichaelGordon: work at Ordnance survey UK, work with public
   sector. combining geospatial data for policy outcomes
   … interested in use cases. worked with office of national
   statistics UK

   billroberts: do you know if Claire is intested in participating
   in this work

   MichaelGordon: I think she is

Organizing the work

   billroberts: suggestions for how to organise our work. this is
   largely copying the way we worked on sdwwg

   <billroberts> 1. Use Cases

   <billroberts> 2. Examples of good practice

   <billroberts> 3. Requirement

   <billroberts> 4. Best practices

   <billroberts> [9]https://www.w3.org/TR/sdw-bp/ and [10]https://

      [9] https://www.w3.org/TR/sdw-bp/
     [10] https://www.w3.org/TR/dwbp/

   billroberts: links are to best practice document lists from
   recent groups

   <billroberts> [11]https://www.w3.org/TR/sdw-ucr/

     [11] https://www.w3.org/TR/sdw-ucr/

   <billroberts> [12]https://github.com/w3c/sdw/tree/gh-pages/

     [12] https://github.com/w3c/sdw/tree/gh-pages/stats-bp

   billroberts: I suggest we follow a similar style. I would like
   people to make a start on use cases and requirements
   … we may need help with permissions set up

   if you weren't in sdwwg, you may not have rights to write

   <billroberts> fd@w3.org

   billroberts: in terms of mechanics, I am happy for people to
   edit directly into these documents
   … happy to pick things up from mailing list

   billroberts: over the next couple of weeks, if everyone can
   start volunteering use cases
   … good and interesting ways people have gone about sharing
   statistical data through the web
   … don't be shy about posting your own work

   ChrisLittle: I would like to highlight problem areas:
   interested in scope
   … many years ago, we used controlled vocabularies: pressure,
   humidity; lots of statistics for these parameters
   … want property language, or attribute language or statistical
   … have parameter names, and statistics list; avoid
   combinatorial explosion
   … vocabulary, ontology? of major statistical parameters. Do you
   think that is in scope?
   … deliverable for OGC Met Ocean domain working group. we have
   statisticains on board now

   <Dennis> i think its in scope

   billroberts: I think this is interesting, it sounds like it is
   in scope

   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
   … complex language, tied up with calendars and coordinate
   reference systems. is this pushing the boundaries of scope to

   billroberts: to some extent, if participants think something is
   in scope it is in scope
   … things may need to be prioritised later

   <Zakim> AndreaPerego, you wanted to point at the UCR template
   of DXWG as a possible alternative to the SDW one

   <AndreaPerego> DXWG UCR (working draft): [13]https://

     [13] https://w3c.github.io/dxwg/ucr/

   AndreaPerego: other group is active, don't know if you are
   aware of this group (link)

   <AndreaPerego> An example: [14]https://w3c.github.io/dxwg/

     [14] https://w3c.github.io/dxwg/ucr/#ID20

   AndreaPerego: structure, including description. has use cases,
   which could be mapped. in github ther is a template for
   capturing issues, within the issue tracker
   … we are looking at the use of DCAT, this could be relevant
   … this group should be aware of the work going on in other
   related activities

   <AndreaPerego> DXWG charter: [15]https://www.w3.org/2017/dxwg/

     [15] https://www.w3.org/2017/dxwg/charter

   billroberts: is that's the stats dcat application profile

   AndreaPerego: no, this is on their github site

   billroberts: it would be good to liaise with those people
   … we don't want to be reinventing things
   … On the use case template: this would add some structure,
   without looking like it would be difficult to use
   … I'd encourage people to add those section if people have the
   information available

   AndreaPerego: the group likes to have evidence about the
   requirements and use cases

   billroberts: are there more comments on chris's questions about
   scope? or other questions about use cases?
   … initially, writing things down will help. It would be good to
   add a use case and an example
   … each

   billroberts: roba welcome. have done round of introductions

   roba: I am here on behalf of OGC, working on next geos project
   … systems mostly have some geostatistical issues
   … sometimes aggregations, or integral
   … worked on sdwwg on qb4st and sdmx, for underlying metamodel
   … this W3 note, I am eager to support evolution of this, if it
   turns out to be useful

   billroberts: this is an interesting one: extends statistics
   into aspects of the coverage domain
   … I am encouraging people to write down initial use cases, and
   note down examples of good practice
   … links in meeting notes

   roba: a lot of sdwwg work was on coverages. sdmx is more about
   statistical areas. some of principles of QB4ST set out
   … need to explore how it links to dggs and register of spatial
   … more work to be done to look at practical realisation
   … getting to the stage of implementation experience

   <kalampokis> [16]https://islab-uom.github.io/qbBestPractices/

     [16] https://islab-uom.github.io/qbBestPractices/

   kalampokis: to warm things up, here is link to challenges
   already defined
   … we would like to discuss these tings in this group
   … keen to extend the work already done

   billroberts: it would be good to have some time in the next
   meeting to go into more details on this

   <roba> (belatedly :-()

   billroberts: final contributions?

   billroberts: please everyone make a start on use cases and

   billroberts: for fixing on next meeting: is this a good time
   for Europeans, Australians, Americans. are there objections to
   sticking with 2000 UTC time slot

   <roba> +1

   <AndreaPerego> +1 from me.

   <josephabhayaratna> +1 from me

   <Dennis> +1 from me

   <MichaelGordon> +1

   <kalampokis> +1

   billroberts: let's stick with this slot

   chrisLittle: OGC meeting in Palmerston North, NZ at OGC; could
   have face to face meeting

   <AndreaPerego> I won't be there, but I can try and join

   marqh: Is the aim for this group to meet fortnightly?

   billroberts: suggest we meet at this time in 2 weeks, then get
   a report in a month's time

   roba: I would like to announce this group to the OGC
   Geosemantics working group

   billroberts: marqh: yes aim for fortnightly meetings

   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
   … at same time as this meeting is scheduled

   josephabhayaratna: OGC meeting may connect via gotomeeting, not
   … would need a good plan for the meeting, present scope, invite
   … could someone put together a slide pack with who we are and

   josephabhayaratna: i'll send template, we can put together
   information via call or email

   <billroberts> bye all

   <AndreaPerego> Thanks, and bye!
