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.
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.
Yes, and a valid reason for making your choice :-) But as you state clearly, it remains a choice with regards to preferred technique.
All:
Where is the pointer (or URL) for a document that mandates 303's? The sense here being: 303 redirection as the only technique for delivering HTTP based Resolvable Names re. Linked Data.
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.
Microsoft doesn't see OData as Linked Data (the concept) competition. They see it as an alternative format for representing Linked Data via E-A-V model graphs :-) As you can see, in this universe of ours, everything is connected, nothing exist in absolute isolation.
Some key points re. OData;
1. It models electronic records rather than real world objects 2. OData modeling ultimately matches any modeling that fails to distinguish a Web Resource from a Real World Object (any Entity that exists in some form outside the Web medium) via fixation -- overt or inadvertent -- on two-thirds of the Referent, Identifier, Resource trinity.
