Hello Bernadette,

I talked about two Use Case types in a big granularity. I agree with what
Phil said in the last telecon that the publisher and the developer are the
same in many cases.

Each one of the Use Case types that I mentioned could be specialized in
other types (as Yaso pointed in the telecon for diferent Open Data
publications). But when you see a hackathon, what we have is a lot of
people, developers, building applications consuming data on the web. Many
times these data are not only Open Data (as we see in the group) but things
that are published in social medias mixed with other kinds of data (I know
that this is out of our scope).

But what I think is that DWBP has one main audience: the publishers. These
best practices could be roughly divided in things related to the data
itself (as the quality), and things that will facilitate the work of the

How the developers will do their work, I guess is out of the scope of the
group. But, for example, one of the best practices of a publisher could be
to present examples or demos of open source apps consuming the data, in a
way that developers could have a starting point to do their work. I don't
know if it is in the scope of DWBP work to suggest a set of documents and
actions that could enhance the comprehension of the data and its usage by
the developers. That was the reason to suggest DBPedia as a Use Case.

Best regards,
