That makes it remarkably similar to

but the t-d-b.org URI has the advantage that it doesn't require a new
URI scheme, and it *might* be dereferenceable by a browser.  In fact, at
the moment it *is* dereferenceable.

That sounds like what the "http://t-d-b.org?" prefix does.

I think the goal is reasonable, but as explained in
I don't think a new URI scheme is necessary to achieve it.  Similar
things can be done with http URIs, with greater benefit.

Right, but "http:" URIs do not necessarily need to be resolved using
HTTP, nor do they necessarily need to be resolved at all.  At worst they
can be treated as opaque strings, but at best they *might* be
dereferenceable to useful information.  A URI prefix like
"http://t-d-b.org?" can become "well known" just as "tdb:" can.  This is
a social issue, independent of whether a new scheme is defined.
