I have edited a typeface (Libre Caslon) and kept only the serifs (and some other stuff, it is inspired from this comic
). I am now wondering what metadata for the typeface I have to change. I work in Glyphs, and there is a nice menu for this type of stuff, however, after reading SIL License, I am not sure how I need to change the credits. Attached is a screenshot, and I would appreciate guidance on what to change.
