Hi,

For these who are not in the call: the connection between duv:Feedback and dqv:(User)Feedback is not yet articulated, we prefer to have them leave a life on their own now. It's better to wait and see how the two vocabularies meet (or not) their requirements, before trying to cross the streams!

(nb: indeed the comment made by Joao Paolo on oa:Annotation and oa:Motivation resonates with the open issue we've put on the DQV Feedback class [1]!)

Cheers,

Antoine

I think we should minimize those dependencies as much as possible, and replace them with more stable and well-known vocabularies, more specifically I mean DCMI Metadata Terms (dct [1], which is already used in DCAT), and the W3C PROV Ontology (prov [2]). I am not sure about the status of  Open Annotation and how we should we use (details below). Further, there are some fragments which do not need to be “reinvented", so we can just reuse. This is to me the case with Application.

Further, I think that we need to be able to reify this Consumption (or Usage if we prefer that other term). This would be a solution similar to what PROV does with respect to attribution. It includes a simples wasAttributedTo, but this can be qualified with an Attribution resource, which reifies the attribution and allows for more information about the attribution to be captured. I think we should do this here because A is actually the core of DUV, and is currently only one property in the whole thing.

So, in my opinion, we should say nothing about this, and therefore introduce no dependence to bibo. With respect to cito, the only thing we would be doing is subClass cito:CitationAct into duv:DataCitationAct (I propose to rename duv:Citation, because since we are using cito, we should use their convention in the nominalization which is better and clarifies that Citation here is an Act.) We should examine this solution altogether, because citing data is already possible without us doing any specialization of the vocabulary. So, B, could be altogether left out from DUV and we could just give examples of how to cite data using cito (and even bibo). If we decide to include duv:DataCitationAct then there should be some reason further than constraining cito:hasCitedEntity to have a range of dcat:Dataset.

However, note that Open Annotation suggests that we do not subclass oa:Annotation because of particular motivations for annotation but instead use SKOS and create instances of oa:Motivation. In this case, we should eliminate duv:Feedback altogether, and just understand User feedback/rating as a new instance of oa:Motivation (e.g., oa:rating). (see current list at [3], which does not include in my opinion something like oa:rating). What currently is duv:has_rating would be some subclass of oa:hasBody (or it would just be oa:hasBody). This requires more discussion as I found the current examples unclear, which bodies of the annotations that are just text.
