locking mechanism for concurrent editing of annotations #170

Closed kimpham54 closed 7 years ago

kimpham54 commented 7 years ago

when concurrent users are trying to edit the same annotation, allow only one user to modify the annotation and prevent other users from editing the annotation

We have a conflict resolution mechanism. If two people are editing at the same time, and one person saves it, we send a notice to the second person indicating that the changes cannot be saved. Not a blocker for release. Putting a note in the documentation so that users know what to expect when multiple people may be editing the same annotation is a good idea.
