Hi,
I tend to see validation on both the client side and server side
frequently, and in our use of Annotator, it was requested to have client
side validation to minimize the server hit for erroneous data.
The only way I've been able to accomplish this is to modify the core by
prepending in the Editor.submit method. It returns if the validation
does not pass (doesn't hit the this.hide()) call. I was not able to
accomplish this without modifying the core. I shared this override in my
list of modified core notes at
https://lists.okfn.org/pipermail/annotator-dev/2014-May/000907.html, and
Randall replied that there is a Editor _onFormSubmit callback that is
not public. I interpreted his further response that this is still being
worked on related to the current refactoring.

Hi Riccardo,
checking annotations in the client my be a good idea. But ultimately,
it should
be checked on the server. Because normally you have no control on what
is sent
via the API and only the server site you can make sure the data
inserted is
consistent.
This is actually an interesting case where using different languages
in the
client and in the server makes things more difficult. If the server is
node.js
based, you can do a validity check in the client and do the same check
on the server...

I found that's a bug introduced by an extension of mine, so there's
no bug in annotator. Anyway it's still interesting understand if it's
possibile validate an annotation before store it.
I tried returning false in the event "annotationCreated" but it
doesn't work.
Thanks,
Riccardo

Hi all, is there a way to check an annotation before it's send to
the store?
I mean, one of my users found a way (I don't know how) to insert
an annotation whose begin is greater than end and I need to avoid the
insertion of those kind of annotations.
Cheers,
Riccardo
