Hi all,

We, from InWeb, agree with the various observations and believe that
refining it is the way to achieve something relevant wrt data enrichment
and DWBP.

First of all, it was never our intention to disrupt the usual process for
generating and publishing W3C documents. We presented a very first
version of the document in the last F2F meeting and since then
have been extending it. We were not sure about the post presentation
process and are sorry for the confusion.

Second, we agree that it may not be a good idea to use "big data",
even as a background motivation for the document, as it is. The
practices reported are applicable to any kind and volume of data.

Third, extending the discussion beyond textual data, although
relevant, may represent a much broader scope. We suggest
to first focus on textual data and later evaluate whether the practices
generalize to other types of data.

Fourth, our rationale in building the document was not really to
provide an exhaustive overview of the methods and techniques for
data enrichment, but what criteria any such method should satisfy.
We understand that this strategy is more compatible with the current
DWPB draft.

Finally, we have discussed quite a lot about whether data enrichment
makes sense in the DWBP draft, and so far, the conclusion has been
that it fits there, but such outcome may change as  we deepen the
discussion in the group. We suggest that you take the current draft just
as a suggestion on how to approach data enrichment in the context of

Thus, how do you guys want to evolve on this issue?
