2 years ago Some fonts were duplicates, and obviously in some of the fonts the wght tag was used for functionally other axes, like Grade etc. This is why the display_name is a list — sorted by descending frequency for each axis name associated with a given tag.

This is bad, and needs to be fixed; seems we need stricted fontbakery checks?
twardoch

2 years ago I propose to mandate "Sentence case", not "Title Case" (so: "Optical size"). Title Case is tedious, confusing and loses semantics. It forces grotesque constructs like "Lowercase X-Height Size" etc.
The OT spec only has one two-word entry ("Optical size"), and it uses Sentence case: https://docs.microsoft.com/en-us/typography/opentype/spec/dvaraxisreg
The registry uses mainly Title Case for the feature names (which shows how inconsistent the spec is editorially): https://docs.microsoft.com/en-us/typography/opentype/spec/features_ae — it’s just a mess: "Case-Sensitive Form" and "Contextual Half-width Spacing" and "Left-to-right glyph alternates".
Nobody really knows how to apply Title Case, so people make mistakes.
twardoch
commented
2 years ago However, the difference between the feature registry and axis registry is: feature names aren’t normally stored inside fonts, so it’s up to app makers to write out the feature names in a friendly way. But axis names ARE stored inside the fonts, so it’s best to ensure some consistency.

2 years ago These are proper nouns so Title Case is best.
twardoch
commented
2 years ago These are not proper nouns. Proper nouns are something like "Africa", "Jupiter", "Sarah" or "Google". Proper nouns are always capitalized, even in Sentence case.
"Size" is a common noun, so it’s only capitalized in Title Case.
twardoch
commented
2 years ago However, even though I have a strong dislike towards Title Case, I have an inclination to accept it for a different reason — English style names in fonts typically use Title Case (like "Light Italic"). And the majority of feature names in the spec use Title Case — though this is inconsistent. The "opsz" axis in the OT spec is labeled "Optical size" (so Sentence case), but if we agree on Title Case, this needs to be ultimately also changed in the OT spec.
I’m happy to go either way (and the full survey I made shows that Title Case is probably more popular). However, we need clear recommendations. I’ll happily write the recommendations, it’s about time to do it.

Yes, and the OpenType Weight axis, the Width axis, are different/distinct from the overall concept of typefaces' weight and width properties. They are, for want of a better word, named instances, ahah
This is frequency data sampled from a range of existing variable fonts.
