Hi Harry,

answering to you and SWEO, this special issue does not require Alistair 
or SWBP involvement.... but forwarded to them for documentation

I checked the document, there are many hints how to implement conneg 
Due to the already-revirewed state of the document, I would not change 
it now based on the recommendation to add more links about conneg...
see below.

It was Harry Halpin who said at the right time 29.03.2008 20:30 the 
following words:

We already refer to the Best Practices document in the section 4.7:
"4.7. Implementing Content Negotiation
The W3C's Semantic Web Best Practices and Deployment Working Group has 
published a document that describes how to implement the solutions 
presented here on the Apache Web server. The Best Practice Recipes for 
Publishing RDF Vocabularies [Recipes] mostly discuss the publication of 
RDF vocabularies, but the ideas can also be applied to other kinds of 
small RDF datasets that are published from static files. "

the second-last paragrpah of 4.7 gives a link to the actual Apache 
documentation about content negotiation:
"To determine the best variant for a particular client, Apache 
multiplies the client's q value for HTML with the configured qs value 
for HTML; and the same for RDF. The variant with the higher number wins. 
Apache's documentation has a section with a detailed description of its 
content negotiation algorithm [ApCN]. HTTP's Accept header is described 
in detail in section 14.1 of the HTTP specification [HTTP-SPEC]. "

I would say that is enough,
4.7 is about content negotiation,
it says to look in the recipes, it refers to apache.
google to the rescue if more information is needed :-)

I aknowledge that we could point more into the recipes, but the reader 
should be clever enough to spot the right part in the recipes.
