[tex-live] license question

[Stephan Hennig]

Hi,

on behalf of the German speaking hyphenation pattern development team
I'd like to ask a question regarding a licensing issue.

We plan to licence our results under different licenses:

(i) the LaTeX package dehyph-exptl with hyphenation patterns under
    LPPL,

(ii) the underlying list of hyphenated words and scripts to
     generate patterns under a copyleft flavoured license.

There's no problem with (i), however for (ii) we're unsure what exact
licence to chose.  I think GPL is more aiming towards software, whereas
some documentation oriented licenses, like GFDL, pose problems to, e.g.,
Debian.  Note, a word list might be the basis for other applications
than word hyphenation, e.g, spell checking.

Now, I fear a word list is neither software nor documentation, but some
sort of a database.  Are there already word lists distributed by TeX
Live or CTAN, e.g., as sources to hyphenation patterns?  Any idea how to
handle such a beast from a licence point of view?  We've thought about
Creative Commons BY-SA, but I've been surprised that CTAN doesn't
provide to chose that among the licences labelled "free".  Is CC-(BY-)SA
considered free by the CTAN and TeX Live teams?  Better suggestions for
a licence?

Best regards,
Stephan Hennig
