A good test case is managing browser bookmarks.  Every tool I have seen
basically constructs a tree, and some of them are very good helping you do
that.  What I really want to do, though, is to put a bookmark into multiple
categories and to add comments and other annotation.  For example, take OPML
itself as a concept.  Presumably is represented by a class or category, I
might like to include the OPML home page under XML languages, List Builders,
Information Organization, Dave Winer's Tools, and who knows where else?

There is no way that OPML is going to let me represent this without
extensions, and without duplicating the bookmark and its url many places.
If you are going both to build your own interface and to extend the design
of OPML, the value of using it seems small.

To the extent that your set of triples are simple property lists, such that
you can write them in hierarchical lists, OPML could be helpful.  But I find
that's not what I usually want to do.
