Well, changing formats is really understood as something different than
building from source. Sure, you can read something different into it and
stretch the meaning of the words but the intent of the license is that
since format conversions are very likely to introduce significant
changes (changing the types of splines, loosing some elements in the
conversion process) *it is* actually creating a derivative that should
be renamed to *prevent collisions* when redistributing it. This is again
to avoid documents which may render unexpectedly why fonts who advertise
themselves with the name of upstream although they don't behave like
To quote the relevant OFL bit:
"Modified Version" refers to any derivative made by adding to, deleting,
or substituting -- in part or in whole -- any of the components of the
Original Version, by changing formats or by porting the Font Software to
a new environment.
A lot of research and community review has gone into finding this tricky
nexus between modifiability and artistic integrity. Seems like it's
doing what it is intended to seeing the growing numbers of fonts
designers trusting this license and the growing number of open fonts
making their way into the distros. I believe we have a much better
situation now than before. Anybody remember Luxi?
