Thanks Ralph, Applications that use the opensearch description document shouldn't care about the URL beyond templated parameters they need to replace - parameters like "r=rss" should only be useful to the server trying to dispatch to the correct handler. Content negotiation is initiated by the client selecting the Url whose "type" attribute is one the client understands, such as Firefox choosing the Url with type="text/html".

I don't know where ya'll are in the comment process, if the group has settled on this, I'll just drop it. However, I think this is a *really* bad approach that should be fleshed out more - mainly to let HTTP take care of conneg. Since OpenSearch was the basis for adding these in, has that group provided feedback on this?

that.  They rely on the URL to do the right thing for them.

Take a look at some of those description documents.  You'll see plenty of
examples of parameters that look like "&r=rss".  That's embedded content
negotiation.

Really?  URLTemplates don't preclude you from regular HTTP content negotiation - it's ultimately just a URL.  I've implemented opensearch and relied on regular HTTP conneg, is there something I'm missing here?

The need comes from the OpenSearch community.  They communicate with servers using URL templates and have no way of specifying the format of the response, other than through parameters in the URL.  So, they, and hence we, must embed content negotiation in our URLs.

I'm reading the sru-2-0-draft dated July 22, 2009.  Is there discussion somewhere that explains the rationale/need for supplying custom http-style parameters (sec 4.9) that duplicate the HTTP Headers themselves?

Thanks, --tim
