Hi Cameron

I'm not sure if it is feasible to have/create a standardized format. I
guess it makes sense to stay as close to LaTex as possible. FOP just put
the patterns into an XML format (using Unicode). It seems to work fine
for us. Java-based CSS3 implementation could easily re-use FOP's
hyphenation module. We rarely have inquiries on the user list concerning

The larger issues is the mess of licenses for the various patterns which
is why we've had to move the patterns outside to http://offo.sf.net
because we can't fulfil the Apache Foundation's license policy. Tracking
down individual authors of the original pattern files and getting
permission to put them under the ALv2 turned out to be a tedious task.
Not all authors can be contacted. So today, the users would essentially
have to check for themselves if the license restrictions are fine for
their particular use case.

There was once a discussion about looking toward OpenOffice (probably
rather LibreOffice today) for re-use of their hyphenation modules. But
that hasn't happened probably due to effort that would need to be
invested for the change. I haven't looked into that closely myself. But
it could be another option for CSS3 implementations.

That said, it would certainly be very very useful to have a good set of
widely usable hyphenation patterns that have a clear, uniform and
permissive license. The current situation is less than ideal for Apache
