We have a fair amount of code which manually builds strings like D123 like this:
$object_name = "D".$revision->getID();
It would be nice to centralize this into the objets, so we just call:
$revision->getObjectName();
However, "object name" is pretty much the vaguest possible name for this. I've primarily avoided building this because getObjectName() is such an ambiguous, garbage method name.
It would be nice to come up with some better name to identify the D123, T123, rX sort of strings we use as local/human object identifiers.
