RE: Disco Hyperdata Browser, a server-side alternative to Tabulator

Hi Chris, Hi Tobias,

Congratulations - this is very cool. Sure enough I have a question... :)

(How) Does Disco handle HTTP 303 redirects?

For instance, I have a slash URI for myself [1] upon which content negotiation is performed. User-agents dereferencing this URI will receive a HTTP 303 to either [2] or [3] depending on the content types accepted. This is based on the Best Practices for Publishing RDF Vocabs recipes, and seems to work fine according to my testing.

However, when I first entered my URI into Disco I got the "No Information to Display" error. After I then entered the URI of the RDF description of me at [3], entering [1] again did produce a page of info about me, taken from my RDF description.

So, it seems that my RDF description correctly references my URI, there's just a problem dereferencing slash URIs that are also content negotiated. URIs in the revyu.com space such as [4] are configured in the same way and suffer the same problem.

Are you able to shed any light on this for me? Or have I missed something obvious?

Cheers,

Tom.
