Unify AGL&AGLFN, glyphNameFormatter and GlyphsInfo licenses

[twardoch]

I’d like to propose that AGL&AGLFN, glyphNameFormatter and GlyphsInfo adopt the same license text, the "BSD 3-Clause Revised License", unified in the way that I’m proposing below.

AGLFN

Currently, https://github.com/adobe-type-tools/agl-aglfn/blob/master/aglfn.txt is licensed under the "BSD 3-Clause Revised License" as follows (it mentions "Adobe" explicitly in the 3rd clause):

(INCLUDING NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE
OF THIS SOFTWARE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGE.

glyphNameFormatter

Currently, https://github.com/LettError/glyphNameFormatter is licensed also under the "BSD 3-Clause Revised License". Virtually identical to Adobe’s, but uses the generic "copyright holder" in 3rd clause.

OF THE POSSIBILITY OF SUCH DAMAGE.

GlyphsInfo

Currently, https://github.com/schriftgestalt/GlyphsInfo is licensed under the "MIT License":

Suggestion

If possible, I’d like to suggest that all three projects change their license as follows:

• AGL & AGLFN, copyright entry:

Copyright 2002-2019 Adobe (http://www.adobe.com/)

• glyphNameFormatter, copyright entry:

Copyright 2016 LettError and Erik van Blokland, TypeMyType and Frederik Berlaen

• GlyphsInfo, copyright entry:

Copyright 2016 Georg Seifert

Then followed by this identical text:

without modification, are permitted provided that the
following conditions are met:

disclaimer.

SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING, BUT

HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN

SOFTWARE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGE.

Effectively:

• for AGL & AGLFN, it does not change the terms, it only replaces the explicit mention for Adobe by "the copyright holder"
• for glyphNameFormatter, it only removes the numbers from the clauses
• for GlyphsInfo, it changes the license from MIT license to the BSD 3-Clause Revised License

We’d gain from this that all three projects would have an identical license, so any composite data made from those projects could simply be credited as:

Copyright 2002-2019 Adobe (http://www.adobe.com/)
Copyright 2016 LettError and Erik van Blokland, TypeMyType and Frederik Berlaen
Copyright 2016 Georg Seifert

plus potential additional contributors, followed by the same text.

I think this would simplify things a lot.

This issue is replicated in all three projects:

• Unify AGL&AGLFN, glyphNameFormatter and GlyphsInfo licenses adobe-type-tools/agl-aglfn#5
• Unify AGL&AGLFN, glyphNameFormatter and GlyphsInfo licenses LettError/glyphNameFormatter#86
• Unify AGL&AGLFN, glyphNameFormatter and GlyphsInfo licenses #25
