plone.app.linkintegrity Package Readme
======================================

Overview
--------

This product tries to integrate PLIP 125 into Plone using the zope3 event
system in order to modify Plone itself as little as possible.


Status
------

At the moment the code handles one of the two use cases of PLIP 125, deleting
an item. Whenever an object that is referred to by another one by an <a> or
<img> tag is going to be deleted, Plone's regular flow of actions is
"interrupted" and a confirmation form is presented to the user. If they then
decide to indeed delete the object the original request is followed through,
hereby breaching link integrity of the site.

This process is implemented independently of how the object is deleted (as
long as ObjectManager's `_delObject` is used ultimatively) and what request is
used to do it. A more detailed explanation of how this works can be found in
NOTES.txt.

The second use case of PLIP 125, which is provides better handling of moved
items, is implemented by plone.app.redirector, available from
https://svn.plone.org/svn/plone/plone.app.redirector/.
