Comment 2 for bug 257401

Beyond just the ISBN fields, the idea that solrize brought up and larger in scope, is to have the ability to lock parts of a page and/or a page temporarily as well as possible vandal attacks, or to keep out spammers similar to how wikipedians can lock wikipedia pages for different periods of time up to indefinite.

For pdregistry.ca vices, the idea is that there is some info that is lockable and harder to edit. If there is this feature, it would be easier to allow this.

For AC they want their original dataset locked, which it is, since new versions are created upon editing and their is a history. ;)
