2 years ago I think that sort of thing would be very useful, and I flagged it in the "New Generation" page at http://www.edrdg.org/wiki/index.php/JMdict:_Next_Generation#Entry-wide_Inflection_Pattern_Elements As I wrote there "The format of the element has yet to be decided." I think we need to get the container first.
Re-posting something I added to the mailing list in 2018 (March 24), that failed to gain traction. Giving it a second go.
Daijisen and Daijirin both list the derivatives -げ, -さ, -み and -がる at the bottom of adjectival entries, as (派生), e.g. for 痛い: daijs:［派生］ －が・る （ 動ラ五［四］ ） －げ （ 形動 ） －さ （ 名 ） －み （ 名 ） daijr: [派生]いたがる［動ラ五］いたげ［形動］いたさ［名］
Would it not be useful to add something like that to entries in JMdict?
Preferably the derivatives shouldn't be bound to any particular sense but be "entry-wide". If it's technically possibly, they could perhaps also take an optional xref value, as we actually have entries for a handful of these derivatives.
on JMDict's 痛い entry, then, these tags could perhaps look like this: [der-mi=1587300] [der-sa] [der-ge] [der-garu=2035530]
(and should, for formatting purposes, preferably appear at the very bottom of the entry)
(there are no entries for 痛さ or 痛げ in jmdict)
I'm thinking a dictionary app could then choose to display it something like this: https://i.imgur.com/GwEAmcg.png (mock-up)
EDIT: we could also maybe add -的 [der-teki] for the various nouns etc. that take it reasonably often, though on the other hand I guess unlike the adjectival derivatives, it can be applied to basically any noun without it being grammatically incorrect, so it'd probably be less useful than the others)
