Hello everyone,

Here goes my view on this:

- I tend to disagree on (former) BP4 being derived from BP1+2+3

BP1 is on metadata availability (provide metadata)
BP2 is on human vs. machine readable metadata (how to present metadata)
BP3 is reusing generic standard metadata terms when possible (i.e. dc, foaf
and the like)
BP4 is about documenting what metadata terms (being reused or ad-hoc) are
you finally using

I don't see overlap between any of the above.

- WRT BP11 Document vocabularies

I don't see any overlap with (fomer) BP4 either as:

BP4 is about documenting what metadata terms are you finally using
BP11 is about documenting your data (not metadata) models (or
"vocabularies") in the case you are developing new ones.

- Finally WRT Annette's comments I think there is a missing point here:
BPXX Document your data

This is about the "data codebooks" that should be accompanying our data as
additional documentation but unfortunately are rarely available making
working with 3rd party data a pain. This "codebooks" usually document all
the information that Annette is refereeing to in her message and more.
