Re: Some thoughts on the Q&G vocab

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

Some thoughts on the Q&G vocab



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.
