Hi all!

Since on the LDOW11 and USEWOD workshops at WWW there was the recent
discussion about using HTTP referrers properly when browsing, crawling
etc. linked data (short using it) I would like to add another thing that I
was wondering about. If endpoints deliver no content to the client e.g. if
the client performs a SPARQL query that yields no results, servers answer
HTTP status code 200 and deliver some content that holds the information
that there were no results. As far as I see, there is the HTTP status code
204 for exactly this, isn't it? (see

So, beside the aforementioned and recently discussed proper usage of
referrers, I would also suggest to use the 204 HTTP status code.
