Hi all, The minutes of yesterday's meeting of the Stats on the Web Best Practices sub-group are available at: https://www.w3.org/2017/11/22-sdw-minutes.html ... and copied as raw text below. Bill introduced the task force and invited participants to share use cases and examples to start with. The sub-group will have calls at the same day and time every two weeks. Next call on Wednesday 6 December 2017 at 20:00 UTC (same WebEx info). Thanks, Francois. ----- SDWIG - Stats on the Web BP 22 November 2017 Attendees Present AndreaPerego, BillRoberts, Dennis, JosephAbhayaratna, Kalampokis, Marqh, MichaelGordon, RobAtkinson Chair billroberts Scribe marqh Contents * [3]Meeting Minutes 1. [4]Background and objectives for this work strand 2. [5]Introductions 3. [6]Organizing the work Meeting Minutes Background and objectives for this work strand billroberts: 2 1/2 years Spatial data on the web working group … working group suggested specific follow on work … statistics on the web: target 'best practice' … timings and aims are in the charter <billroberts> [7]https://www.w3.org/2017/sdwig/ [7] https://www.w3.org/2017/sdwig/ <billroberts> [8]https://www.w3.org/2017/sdwig/charter.html [8] https://www.w3.org/2017/sdwig/charter.html billroberts: aim to complete half way through 2019 Introductions 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 statistics 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 sets … 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:// www.w3.org/TR/dwbp/ [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/ stats-bp [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 language … 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 far 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:// w3c.github.io/dxwg/ucr/ [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/ ucr/#ID20 [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/ charter [15] https://www.w3.org/2017/dxwg/charter billroberts: is that's the stats dcat application profile group? 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 standards … 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 examples 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 remotely 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 webex … would need a good plan for the meeting, present scope, invite comments … could someone put together a slide pack with who we are and scope? josephabhayaratna: i'll send template, we can put together information via call or email <billroberts> bye all <AndreaPerego> Thanks, and bye!
