I have all the older versions if you want.  In fact, 0.52 is zipped up here
[1] along with the very first versions of the spec.

I suspect that's true, yes.  It's only half completed, just as a
demonstrator that JS apps could be written against the RO API.   And, in
fact, it doesn't yet provide the mechanism to invoke object actions, merely
to browse between objects.  (The first page that lists all todo items is

One of the benefits of having a small community is that no-one's beating
our door down to get 0.3.1-incubating released.  So, yes, in my opinion we
should complete ISIS-233 before 0.3.1-incubating is released.

As you've seen, I'm also working on ISIS-14 (the JDO object store); I want
this piece of work to be complete too.

What I suggest is that you go ahead and make the changes to the
restfulobjects-viewer as need be, in whatever order works.  Hopefully
before too long that'll end up taking it to v1.0.0 anyway.  But if you
don't have that amount of time or get sidetracked, then I'll chip in to
complete the work before we release 0.3.1-incubating.
