Need to get back to merging this!

On the default filter functions (in part to ensure it works correctly), what might they be?

Any thoughts @roshanshariff?

I suppose another option is non-breaking: to add a new defcustom specifically for this, and keep the existing one the same.

I'll look at this more deeply in a few days, but I wonder if most of this functionality should be in Citar? It could be useful to define some "virtual fields" there which are basically some bibliography fields, transformed by a filter function. You might want to use these in Citar templates as well. Perhaps citar-org-roam should just expose these Citar fields in Org-Roam templates?

Yeah, I was thinking something in citar itself might be better, but just not sure how that might work.

There's no real urgency here; just wanted to resolve this, since it's been sitting here awhile.

Use cases I'm thinking about are in the linked issue.

I'm going to close this in favor of the core package-only transform functions.
