Hi Hugh,

[@Nathan, thanks for forwarding it to the Virtuoso list; I subscribed there
now, but I thought the question might also be of a more general interest
w.r.t.  deploying hash URIs.]

Thanks, I had looked there before, but got the impression that that guide only
deals with the very special case of the "this" pseudo fragment ID, i.e. a
workaround of introducing hash URIs to facilitate content negotiation.  I got
that impression because the guide talks about http://.../ALFKI#this, where
"ALFKI" is the entity of interest.  Please let me know if I got something
wrong.

In our situation, we have many entities of interest, with the following URIs:

http://.../document (without fragment)
http://.../document#fragment1
http://.../document#fragment2
...

and when a client requests RDF/XML from http://.../document, the client should
get a document that contains all triples for http://.../document,
http://.../document#fragment1, http://.../document#fragment2, etc.

(Note that we were not free to choose this URI format; it was given before we
went "linked data".)

Cheers, and thanks,

Christoph
