I have basically added those IFPs and FPs which seemed to make sense
and which allow one to uniquely nail (indirectly name) every bnode in
a calendar graph.  This is for making patches from changes files,
as in  http://www.w3.org/DesignIssues/Diff

Currently, delta.py will take extra metadata files with --meta=ifps.n3
but it would be much nicer to have them in the ontology: I'd
like them to represent community understanding.

The remaining issues are just the lack of UIDs on calendars themselves
and on alarms. Both these have X- identifiers in various clients, but
that doesn't help if they are not generally supported.

The calendar ID issue is easy: there is normally one per file,
and it can be passed as a parameter at conversion time.

A possibility with alarms is to regard them as structured datatypes,
so basically concatenating their parameters (offset time, noise, etc)
as strings gives a sort of name.
