ChrisLittle_: +1 pointing out SDMX has been around with
international statistical best practice - foundation for RDF-QB
- other stuff never made it - need to understand scope and
limitations
billroberts: notes SDMX is difficult to read 250 page type
doc...
AndreaPerego: analysis was a quick and dirty job, statistical
data not core business...
… as a template to identify where we have BP already, where
gaps
… URIs not part of of SDMX - have internally scoped identifiers
… need to provide guidance here
… discussion about not being too RDF biased - how do we apply -
e.g., what about CSV on Web? Can it play a role for making stat
data webby?
… BP work identifies number of possible options
… some BP were about metadata and some about data
… RDF-QB can be about both
… SDMX metadata is often free text - although often it
describes some information very accurately, and covering
different aspects (e.g., data quality)
<billroberts> (Yes I think that's accurate Rob)
AndreaPerego: should at least address DWBP cllauses
toba: SDMX has a lot of different things mixed in one standard,
which is what makes it complex. RDF-QB pulled out the core
model of it, without doing all the codelists
... which I think was the right thing to do. But leaves a gap
in that the many codelists in SDMX are not a core part of
RDF-QB , but they are not necessarily stably governed
... so there is a general challenge for these kind of BPs of
how do we put up standard maintained vocabs that can be re-used
... When looking at QB4ST, i deliberately scoped it to metadata
(not data) and considered it as a canonical version of a
conceptual model. Could certainly have been in other syntaxes
...JSON-LD version of RDF-QB is quite straightforward
.... We don't have to solve all problems: a reasonable scope
would be metadata to describe whatever representation we have,
using RDF-QB as core, and allowing RDF or JSON expression of it
<ChrisLittle_> +1 to focus on metadata
billroberts: agree we shoudl focus on web specific aspect
ChrisLittle_: notes QB4ST perspective that the "big data cubes"
arenot going to leave their existing implementation choices for
data encoding and access mechanisms
billroberts: DXWG needs folllowing
<billroberts> [10]http://ggim.un.org/meetings/GGIM-committee/

ramework.pdf

<AndreaPerego> Just to say UNGGIM was also mentioned during the
SDW BP call.
roba:Data Exchange WG has just released first draft of
requirements. Not had much feedback yet
...would be great to have some feedback from this group to DXWG
(and not from Rob as he is an editor of it)
...so please everyone do send comments to DXWG on that
requirements doc
...Description of profiles and negotiation of which one you get
is something DXWG is looking at
...It's more than negotiating data format, but rather
negotiating by profile - could be a useful angle for us
...DXWG won't define specific profiles - that would be down to
other groups, eg SDWIG
...so we could try to come up with a profile for metadata for
statistics in that framework
<AndreaPerego> +1
[11]https://www.w3.org/TR/dcat-ucr/ has details on how to
comment in intro
[11] https://www.w3.org/TR/dcat-ucr/
josephabhayaratna: has a set of comments from ABS on this
groups UC, yet to write up and submit
marqh: helpful to have explicit examples
billroberts: using RDF-QB in real world - can bring forward
some examples
marqh: sounds really helpful
Action: bill roberts bring forwards RDF-QB examples from
experience
<trackbot> Created ACTION-380 - Roberts bring forwards rdf-qb
examples from experience [on Bill Roberts - due 2018-01-31].
F2F meeting in Amersfoort
<billroberts> [12]https://w3c.github.io/sdw/meetings/f2f-1.html
[12] https://w3c.github.io/sdw/meetings/f2f-1.html
-1 for F2F
<ChrisLittle_> Chris planning to
<AndreaPerego> Not sure I can make it... But try to join
remotely.
<josephabhayaratna> I won't be there
roba: have some kind of plenary catchup that they could dial in
to but not very productive to join a F2F meeting remotely
roba: if possible, spend some time reviewing possible examples
and identify the most useful to get principles across to
audience
<ChrisLittle_> +1 to >1/2 day
roba: I've been working as an OGC staff member to bring the
definition publication capability in-house from a skunkworks
project that SImon Cox started
... so there should be a crude CMS able to publish and maintain
registers of terms as linked data. Hence OGC will be able to
publish vocabs on behalf of working groups and something we can
take advantage of
...The process would be to approach the naming authority to ask
for a namespace. Early days but should be possible
...eg for SDMX codelists say
...ISO TC211 might use this
...can include automatic entailment, eg of broader/narrower
relations
...but main decisions are around governance and that will be
done on a case to case basis
<ChrisLittle_> bye
<AndreaPerego> Bye!
<billroberts> bye all, thanks
