Nicolas (S), Thanks for your contribution to the thread! More below. <div class="gmail_quote">On Sat, Feb 14, 2009 at 3:51 PM, Nicolas Spalinger <<a href="mailto:nicolas_spalinger@sil.org">nicolas_spalinger@sil.org</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">The OFL doesn't refuse to admit that font sources exist - rather the contrary - it acknowledges the fact that beyond the binary font files themselves, which you can already do something with, there are a lot of different elements which can be used as extended font sources. It avoids the problematic question of defining precise source requirements for the "preferred form of modification" when there are various ways of modifying and building a font: "preferred" for who exactly? A very strict source requirement would alienate the vast majority of designers we want to see joining our community! </blockquote><div> I agree that the question of sources is very tricky, and probably for the majority of fonts, it doesn't make sense. In that sense, I think the OFL is a realistic license. </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> So the OFL model intentionally doesn't place strict requirements on releasing these extended sources needed for a full build but at the same time it *makes it possible and strongly encourages* (via the FAQ) the author choosing this model to release everything that can be useful to designers: data files, glyph databases, smart code, build scripts, documentation and rendering samples.</blockquote></div> However, in the case that I actually have sources (and more than just build scripts), I want those to be protected in the sense that modification of those sources must also be redistributed along with the corresponding modified font. I don't see that the OFL would require this, and so I don't see the OFL as the right license for the sources. Best wishes, Stephen
