Thanks, Andrew. It turns out the problem was that I had been using the name
"id" instead of "text" for the element. Now that I've changed that, I was
able to successfully create the corpus in CQPweb.

My source files have quite a bit of metadata, which I've encoded as follows:

I'm now at the CQPweb "Design and insert a text-metadata table for the
corpus" page, but it tells me that "No XML annotations found for this
corpus". Is there something wrong with how I did the encoding above? I can
use all of these XML elements in cqp searches directly, but here they
aren't recognized.

(I've checked chapter 6 of the manual, to no avail).

Best wishes,
Scott
