ISSUE-221 Alignment with http://www.w3.org/2001/sw/hcls/notes/hcls-dataset/-
worst case, we can Postpone the issue saying "We acknowledge the importance of connecting DQV to domain-specific profiles such as the HCLS Community Profile. Exploring these relations requires more work than what we could provide in the Working Group. We postpone this issue considering that relation between DCAT application profiles and DQV is likely to me more extensively addressed in an upcoming working group."

https://www.w3.org/2013/dwbp/track/issues/225 - https://www.w3.org/2013/dwbp/track/issues/223 To be closed after the appendix "Defining and using parameters on metrics" is finished

Guillaume Duffes http://lists.w3.org/Archives/Public/public-dwbp-comments/2016Jan/0056.html -
perhaps in some cases we will have to reply something that sounds like " sorry, that would be interesting but currently there is no space for considering that, you can extend DQV in that direction"

Question from SDW WG on representing precision and accuracy https://www.w3.org/2013/dwbp/track/actions/271 (Examples have been double-checked by Andrea Perego (see thread, and the section has been revised by Antoine, the action can be closed)-
An extra example about :spatialResolutionAsAngularDistance has been discussed in [1], should we consider to add it in a future ??

Question from Pierre-Yves about having content negotiation for DQV: https://twitter.com/pyvandenbussche/status/733631531193884672-
Side action would be to create an HTML representation of the voc like https://www.w3.org/2009/08/skos-reference/skos.html. We have it almost already, with the tables: https://www.w3.org/TR/vocab-dqv/#VocabularySpecification . In fact creating an HTML representation of the voc would allow us to make the main spec a bit lighter!

Less important issues, which we can close quickly when needed, as we have a basic solution

https://www.w3.org/2013/dwbp/track/issues/201 has 4 actions:-
https://www.w3.org/2013/dwbp/track/actions/256 -
https://www.w3.org/2013/dwbp/track/actions/259 -
https://www.w3.org/2013/dwbp/track/actions/258 (action done, jeremy feels unconfortable with it 1, Riccardo 2 and Antoine 3 explained the rationatle behind this choice, Jeremy is still not buying it and asking for the group opinion? no Group opinion provided, so after a month, as the action was anyway done, we have closed it. ) -

Backburner issue, probably to come back to at the last moment
https://www.w3.org/2013/dwbp/track/actions/263-
In fact a big related issue is whether to keep dqv:value only for literal values or to use any resource that looks like a measure, as several have suggested (esp. Zaveri and Dumontier) see also discussion with Andrea
-
Other "non-official" issues:
-
Do we need both dqv:hasQualityMeasurement and dqv:computedOn? -
Express an axiom relating dqv:hasQualityAnnotation and oa:hasTarget. -
problem with double arrow that is not about inverse property (raised with DUV, we might have some as well, or be careful not to introduce new ones) -
we may (quite unlikely) want to come back to the huge discussion on completeness http://www.w3.org/2013/dwbp/track/actions/153 - we could try and relate results of tests like RDFUnit into DQV. Also tests themselves (as per provenance discussions) [AI: can we consider that this is done by https://github.com/AKSW/RDFUnit/tree/master/rdfunit-w3c-dqv. A warning though: I have not checked their implementation. Riccardo, have you?]
