Fwd: Quick comments on DQV after F2F meeting.

This mail is the beginning of a thread that has not been archived. I'll 
forward the others immediately as well.

All substantive comments on the WG's work MUST be in this archive.

Thanks

Dear Antoine and Christophe,

let me drop you some quick comments resulting from the F2F and off-line
chat I had with Phil and Deirdre.
@ Phil and Deirdre: please correct me if I have misunderstood any of your
points.

1) Phil suggests that we have out the FPWD of the  Quality Vocabulary at
the end of May, not at mid/late June.
  According to Phil, this is necessary due  to issues related to the
management of the group and his need to report to W3C on group advancements
.

So,   Phil's idea would be  to  keep the schedule proposed  by Antoine in
[1], but having the FPWD out  based on   "Spec, first version of the
vocabulary" which is  expected by 22nd of May, and  then, to face  the
  rest of the activity  as  part of comments/ feedbacks /refinement of the
FPWD.

2) I think we had some useful feedbacks from  the  F2F discussion  on
quality [2],  in particular we had an agreement on
-  what quality dimensions we might  start with, namely dimension from  the
Open Data Support list and Makx's Share-PSI session (see action [3] and
related resolution)
and  a sort of agreement on
- the  adoption of DAQ as starting point especially to represent quality
dimensions and computed  metrics.
- the need that other representations of quality are  somehow considered
besides  computed metrics,  e.g.,  we should be able to say that the
quality is described in an SLA (see action [4]), or the data set is
compliant to a given "standard", best practice set  ect.

I know this is still far from the set of  requirements we might need to
share with the group in order to design the DQV, but  at the same time, I
tend to agree with  Phil and Deirdre: we should move on, get a first draft
that makes sense for us, and that will force the discussion on more
specific issues,  that will probably help eliciting/revising the list of
requirements  and  in building a   consensus on those requirements the
group hasn't yet agreed on.

In this respect,  I hope next week I will be able to find a  proper slot to
incorporate DCAT, Jeremy's DAQ, and  non-metric-based  quality
representations in a  very early draft  concept schema for DQV.  No Rocket
science, just  a very  early draft ( 3/ 4 entities and few relations)  we
can reason and refine on. Do you think that might help? Do you want me to
do it? Or we have already people working on this?

3)  it seems that,  from here to end of May, we will have  at least a
  Friday-call fully dedicated to DQV. Deirdre is suggesting to have a "DQV
Friday"  the next Friday  (the 22nd of May), and she was  also one  of
those suggesting we should  get an early draft schema  of concepts to
discuss.

If I you want me  to provide such early concept schema draft, I would
recommend to have the DQV dedicated Friday call a week later (29Th instead
of 22nd). That, in order  to be sure that  Antoine, Christophe and Deirdre
can comment/ amend  my draft and  we can discuss  a more
significative/stable version with the rest of the  group.

What do you think?


Best,
Riccardo
