Is there a generic way to name what are usually the 'time' and
'frequency' domains for digital filtering?

I seek a single term that can be applied for instance when the data to
be filtered may be a (frequency) spectrum, or spatial positions, or
angles.

I'd suggest 'Measured Domain' and 'Transformed Domain'.

I've seen references to "data domain" and "transform domain".

this isn't really the answer to your question but instead of
"frequency domain", i sometimes say "reciprocal-<unit> domain".

but, i remember once having trouble explaining what little i knew
about image processing. can't remember what i called the x and y axis
of the pic. "length domain" or more likely "position domain", i
dunno. but i called the other one the "frequency domain" and that
didn't make sense (if we got careless with units) so i called it
"reciprocal-position" or something like that.

"Spatial frequency" is widely used. "Wave number" seems too abstruse to me.
