Not at all. My own xjdic is GPLed. It's in /debian/pool/contrib/x/xjdic
among other places.

I've seen that comment which Glenn Rosenthal added on the JFC page after
he quotes the GPL text. He actually says ".. without the explicit permission
of the respective copyright holder(s)."

I have heard that Debian has problems with this approach. Of course xjdic
doesn't *need* EDICT; it can use any Japanese/English file in the right
format. As far as I am concerned the software and its data are decoupled
in this case.

Exactly. edict-el and xjdic are in the same boat. I see edict-el is in

Sorry, that "either" is a left-over from a earlier version.

Up to a point. The problem with putting a data file under the GPL is that
a dataset is probably far enough off from the program source of a program
that accesses it that the "you must release the source" dictum may not

The issue came up years ago with RMS, and has been touched on a few times
since. The problem is that a lot of contributors provided data which was
their IP on the condition of no commercial exploitation. I have got
agreement that that be extended to the sort of non-exclusive licence for
