Hello Laufer,

Thanks for you message!

I really like your point of view and I agree with you when you say that we
have two types of Use Case. In my opinion, they are similar to the two
types of use case presented in the Use Cases and Lessons for the Data Cube
Vocabulary [1]: Publisher Use Case and Consumer Use. However, if we divide
the cycle of publishing data on the Web in more than two steps (publishing
and consuming), as proposed in [2], then maybe we will have more than two
types of Use Case.

Our initial idea with the Use Cases Document was to extract some standard
Use Cases from the set of stories and use cases that will be gathered.
Then, for each type of use case, we could define the main general
challenges and maybe some best practices. However, for doing this we should
have a larger number of stories and use cases.

I also agree that the audience of the DWBP should be the publishers and
that we should listen the developers (consumers) to better understand what
they expect from the published data.

Concerning DBpedia, I think that this is a great example of publishing data
on the Web and that it could be interesting to have a use case like this.

Best regards,
