Re: DWBP vocabularies and annotations

Annette,

First of all thank you for pointing us to the Web Annotations Motivations
in April after our F2F.  I have found this to be very useful.  Our approach
has been to make a subclass of duv:Feedback
http://w3c.github.io/dwbp/vocab-du.html#vocabulary-specification so that we
inherit all aspects of the Annotation class.

I am reluctant to just use the Annotation class as a substitute for our
subclass solution, because we are trying to model specific requirements for
feedback on datasets as opposed to a generic annotation about any web
resource.

Without a subclass it becomes clumsy from a search and discovery standpoint
separating feedback about the dataset from generic annotations, because I
would lack a crucial part of a query pattern needed to hone in on what I'm
after and any of my queries would require a secondary step for filtering
any annotation that was not related directly to the aspect of feedback.

Another solution just using generic annotations is annotating the
annotation to declare that this feedback on data usage, but again declaring
a subclass does that for me.

Does this make sense to you?

Cheers,

Eric
