Funny, I would have said this the other way around (new points back to old, then the system services can provide the old -> new capability -- or is this what you are saying too?). I have this notion that *any* change to a static resource's specifications -- definition, metadata, semantics -- makes a new resource (this lets me compare resource_new to resource_old and see the difference between them unambiguously). With this vision, the resource can't change once it is created, even to point to a new resource (you see the problem). Is this vision just plain wrong, per the consensus?

The difficulty is that the community uses every tool and standard in the universe (!), many of them custom and one-off programs, most of them severely non-semantic, and many not very sophisticated, in this context at least. So it isn't like we change "the standard tools" because there are no standard tools. And the cost of making the changes (assuming we agree on all the changes to make) is high compared to the funds available to make the changes, and the larger community just does not see the need (yet). Yes we can address the semantic part, but we need a major consensus on broad approaches to have that attitude impact actual community usage.
