[annotator-dev] Commenting on annotations

Mon Mar 12 12:26:20 UTC 2012

Hi All,

There was some discussion on GitHub about making comments on existing
annotations. One idea was to make an annotation viewable and then enable
the annotator on that html view, allowing more annotations to be made:
https://github.com/okfn/annotator-store/issues/32
Another idea was to add a parent field to each annotation and, I guess,
allow one to give input that is linked an annotation. Almost like a
linked-list kindof model.

Has anyone done anything about this? We are thinking of adding this
functionality but don't want to go through the motions if it will duplicate
someone else's work.

Our idea is as follows: Another database object is created, lets call it
'comment'. A comment is an object that contains a subset of the annotation
object, effectively (so maybe we can use the annotation objects for this).
Each comment object is linked to a parent annotation object (maybe via the
db id?) . It also contains a userid, creation date and the comment text
itself.

The user interface is to be tweaked with a plugin so that the annotation
view has an extra button that pops up an entry field, where a user can
enter a comment. It also contains a little blurb containing something like
"5 Comments". Mouseover on an annotation will surface all the comments in
one of the page margins, much like an annotation is showed when the cursor
is on it.

This is not very complicated as far as I can see and shouldn't impact the
rest of the annotator system. Will this be useful to anyone else? Does
anyone have another idea for this?
