Re: Some thoughts on the Q&G vocab

Hi Phil,

We already defined most of the concepts [1] (probably not in that detail) you are currently specifying, which will be used for the DIACHRON project (@Steve, we have 4 “customers (project partners)” there - Datapublica[2], Data Market[3], EBI[4] and Brox[5]). We will have a namespace as well for that (probably a purl namespace for now). Those are also based on the conceptual daQ model (linked by Ghislain in this thread) I presented to you in our f2f meeting.

I suggest that rather than duplicate the effort, we should first define a number of domain-independent quality dimensions (some customers would require different dimensions and metrics). Then we could identify the properties for each of these dimensions (we could either use Makx’s work and Amrapali’s [6] survey paper). If daQ is used, then it should also be easier to integrate quality metadata to CKAN.

@Phil, I’d also be happy to help you with the ontology modelling.

Cheers,
Jer

Phil,

Good work!

When we have vocabulary specifications ready to be tested, I can find a "customer" to test it as an implementation use case that we can document to make "recommendations."


Best Regards,

Steve

Dear all,

As mentioned on today's call, I've been looking at the data quality and
granularity vocabulary. Taking the discussion at the f2f meeting [1],
Makx's work under the Eu ISA Programme [2] and the ODI Certificates [3]
as my starting points, I worked through the issues and made notes in the
wiki. Based on that I then created the diagram. All of which is
available at [4].

Eric - you kindly offered to help with the UML modelling, thank you.
I've used Enterprise Architect for this - is that what you use by any
chance?

I think there are several high level talking points:

1. What are we trying to achieve - machine readability? Links to human
readable documentation? Objectivity? Subjectivity?

2. How are we going to test this? Bernadette is building a CKAN
extension for the data usage vocab - Bernadette - can it take on this
vocab as well? (I hope so). The plan so far is for the two vocabs to be
Notes, not Recommendations. That means we don't have to prove
implementation. However... without implementation nothing is a standard
and if we can take the vocabs through to Recommendation (i.e. prove
multiple implementations) then they'll have a lot more weight.

Any and all comments welcome. If focussing on a particular issue, please
start a new thread.

Cheers

Phil.
