Hi all,

The subject of this email is the title of a blog post I wrote last night questioning whether we actually need to continue with the 303 redirect approach for Linked Data. My suggestion is that replacing it with a 200 is in practice harmless and that nothing actually breaks on the web. Please take a moment to read it if you are interested.

http://iand.posterous.com/is-303-really-necessary

In a purely personal capacity, I like the approach of just using 200, i.e. with RDFa or whatever, rather than 303. If we want to disambiguate URIs, the IRW ontology [1] offers a nice class called "nonInformationResource" and "InformationResource" that one can use to disambiguate. See this paper [2] on "an Ontology of Resources for Linked Data" for a walk-through example.

My reasoning is not architectural, but simply efficiency. It is rather inefficient to have a redirection in the form of a 303 if one can get the same info without using 303.

Note that Microsoft's oData may one day be a serious competitor to Linked Data, and if you asked many programmers and open data people who are not already committed to RDF if they would use Atom + HTTP GET and no redirects over RDF/XML and a weird 303 redirect, I think the answer would be rather self-evident.
