I have added another proposal for dealing with imports. I have produced a concrete wording that we might use; please take a look at


The proposal is in its essence identical to Peter's, with a more explicit statement of what an implementation can do. It is also
quite similar to Jeremy's proposal; the main difference is that I stated everything in more general terms than just caching: I
believe that this is a more general than caching and it actually the issue of locating one's ontologies.

Let me know if you have any comments.
