No not planned but interesting, and should probably be stored in the
datastore.  This is because you can easily do full text search across
all the tabular data already.  The datastorer could be pretty
trivially extended to do this as long as the document parsers do not
require to much work.  It would be very useful to have a core language
metadata field/ posibably per resource if we were going to index
textual documents.

Yes, not particularly well tested, and got a reasonably large barrier
to entry, but definitely there.  It is actually not done as a param
but as as a top level entity i.e
datahubio/my_dataset/new
A custom extension can define what it can be called, its schema and its form.
