<tt><font size="2">The idea behind this when we originally implemented notifications in Keystone was to </font></tt><br>
<tt><font size="2">provide the resource being changed, such as 'user', 'project', 'trust' and the uuid of that</font></tt><br>
<tt><font size="2">resource. From there your plugin and could request more information from Keystone by doing a</font></tt><br>
<tt><font size="2">GET on that resource. This way would could keep the payload of the notification sent minimal</font></tt><br>
<tt><font size="2">in case all the information on the resource wasn't required. </font></tt><br>
