I don't know.

I mainly extrapolated from your example.  Further, I extrapolated from the
notion of org-inlinetasks.el.  Since we have one we should try to minimize
the distance whilst still keeping syntax as simple as possible,
e.g. [comment:] or [TODO-TAG:] (I don't know what the "@" operator meant
in your previous example).

Isn't this the job of VC?  I'm not sure how we can concisely represent all
the needed metadata?  Something like

     [comment: txt :annotation annot :author a :date d :other-properties p]

is not "accessible" for non-Emacs users of the Org format.

This is a fortification/overlay issue.  And I disagree strongly on having
invisible parts.

What do you concretely have in mind here?  Can't this be done with an
inlinetask at the beginning of the file?  Or a noexport heading?

Is this not the job of VC?

This seems like the job of e.g. vc-annotate.el, no?

What John was talking about was for collaboration.  When you export John's
notes on your machine how can it know it's from John if not set
explicitly?  In any case, I think it could be too verbose.  Sidenote: In
collaborated papers I simply use prefix "R:" and "K:" in inlinetasks.

Nothing with curly braces is nice :)

I think I have something much less ambitious in mind, as I'm perfectly
happy with only spanning a subset of org-inlinetasks.el.  Disregarding
date and generalizing replacement text to "annotation", which could be set
to "replace" with a keyword, you could perhaps have something like one of
these:


[comment/Property:annotation; text]
[comment/address@hidden: annotation; text]
[comment/Property: annotation]

[TODO-TAG/address@hidden: annotation; text]
[comment/Property: annotation]

- Of course the / and @ operators are optional.
- I'm not sure what "Property" would be.
- Author could also be @work as in your previous example.
- Perhaps calculating TODO-TAGS on a document basis is a can of worms.
- I would be happier with having text before annotation, but that makes it
  weird when you have no text attached (for inline tasks not associated to
  a piece of text).
