any good hacks for these?

Four different problems that as far as I know don't yet have single standard
solutions. I'd be very interested in hearing how people are dealing with
these in practice.

1. A context thing. Say we have an RDF file containing a set of assertions,
and we want to load this into our system. The only thing is, we need to know
that these assertions came from the same (identified) source. Internally we
can use a quad type model or whatever, but if we want to merge these
assertions with another set and pass them on, how can this be done whilst
maintaining an association between the source and the assertions?

2. Properties-as-instances. How to treat the arc of a statement in the same
fashion as the nodes. This came up recently, and I think the main suggestion
was to make new property classes as required. This still strikes me as
rather clunky for implementation, are there any good workarounds out there?

3. Weightings/confidence factors. I'll probably (0.5) be having cocoa
shortly. Or even, isEquivalentToMaybe[-.1].  Any neat approaches?

4. Stuff. How does one handle a continuum/mixture of non-atomic stuff? As a
subclass of owl:Thing?
