Many thanks for your reply, Hans.
In order to be able to start an entry in the wiki about variable fonts,
axes are only accesible using their name (not their tag) in the axis
section (not in the design axis section), aren't they?
And each font feature requires a new font instance (unlike other font
features such as small caps or many other OpenType features), doesn't it?

I don't know whether this is too complex to be implemented, but it would
ease the use of optical sizes in this case.
Many thanks for your help,
Pablo

there is no axis defined for italic (it's a design axis so that's
probably why you have two fonts one with italic in the name)
so, just forget about it
Many thanks for your reply, Hans.
It seems that Literata has what they call an upright italic
(https://raw.githubusercontent.com/googlefonts/literata/main/Documentation/DS_Literata3.pdf#search=upright).
But I’m afraid I cannot use weight (when invoked as 'wght'). Optical
sizes don’t seem to work.
The following code shows the issue I’m experiencing:
\definefontfeature[myaxis][axis={wght=100, opsz=1.0}]
\definefontfamily[mainface][rm][Literata]
[features={default, myaxis}, designsize=auto]
\setupbodyfont[mainface]
\starttext
\scale[width=\textwidth]
{\switchtobodyfont[7pt]\tf Regular, \it Italic}
\scale[width=\textwidth]
{\switchtobodyfont[12pt]\tf Regular, \it Italic}
\scale[width=\textwidth]
{\switchtobodyfont[36pt]\tf Regular, \it Italic}
\scale[width=\textwidth]
{\switchtobodyfont[72pt]\tf Regular, \it Italic}
\stoptext
What am I missing here?
\definefontfeature[myaxisa][axis={weight=200,optical size=12}]
\definefontfeature[myaxisb][axis={weight=200,optical size=42}]
\definefontfeature[myaxisc][axis={weight=200,optical size=72}]
\usemodule[fonts-variable]
\starttext
\definedfont[file:literata.ttf*default,myaxisa] Some Text\par
\definedfont[file:literata.ttf*default,myaxisb] Some Text\par
\definedfont[file:literata.ttf*default,myaxisc] Some Text\par
\stoptext
optical size looks rather useless
btw, we don't check for optical size in relation to the asked size anyway

Dear list,

Other axes than weight (and only when not invoked as 'wght') don’t work

\usemodule[fonts-variable]
\starttext
\showfontvariations[font=file:literata-italic.ttf]
\showfontvariations[font=file:literata.ttf]

It reports that the Literata fonts have three (design) axes: wght, opsz
and ital. ital is only a design axis.
As explained before, they don’t work for me. How can I access to the
