Hi,
I recall asking about retrieval of remote RDF using the FROM clause in
TDF/Fuseki queries awhile back, and at that time it was possible, or
rather some coding had to be done / ported over from Joseki.
I've just tested this again, and it doesn't appear to be possible. Can
anyone verify this or give more info?
Thanks,

With TDB, FROM is interpreted as picking graphs out of the dataset, not
from the web.

If you're planning on wanting to combine web data with your database,
consider getting a local copy in the database (SPARQL Update LOAD), or,
inefficiently, a general dataset, including some TDB models. But you
end up bypassing some of TDB optimizer because when querying a dataset
it can do more than just one graph (e.g. move FILTERs around, or do quad
based queries).
