Thanks Graham!

For the records, I am satisfied with the responses.

Thanks again

But this is not the case. However, 4.1.1. says that the URI template defines what is used, ie, I can have a service using a different convention, say, &resource=.... I believe this should be made clearer in the text.

Or should it provide at least one of these? (In which case how does it say which one it can support?)

In the absence of a clear consensus on a specified format, I thought we were taking a fairly loose approach for now, with a view to seeing what applications choose to support.  If I'd been asked about this a year ago, I'd have said that RDF/XML MUST be supported, others are optional.  For a long time, RDF/XML was *the* standard syntax for RDF.  But the mood seems to be shifting towards Turtle as the most popular format.

The service description presented here may be supplied as RDF (in any of its common serializations as determined by HTTP content negotiation), and it may contain descriptions of one or more available query mechanisms. Each query mechanism is associated with an RDF type, as explained below. (The presentation here of RDF service descriptions does not preclude use of non-RDF formats selectable by HTTP content negotiation.)
