Re: [Treebase-devel] reconfiguring the purls

[Rutger V. <rut...@gm...>]

I think the problem we want to solve is that we can give a canonical
treebase purl to a linkeddata browser and it can do something with it,
whether that's through conneg is almost secondary. Linkeddata browsers
apparently (according to @rdmpage, mind) expect 303, but our purls
give them 302. They won't know what to do with that, so until we
reconfigure our purls, we can't use them in a linkeddata context.

LD is somewhat being glued together by convention, so I'm as baffled
as you - but if the convention is 303 and we wanna play, we'll have to
do 303 also.

Right, the canonical thing URI would be the purl, and the different
serializations describing it are identified by the phylows
"?format=$foo" query string parameter.

Really? I interpret the examples I've seen as 303, not 302.

I'll try to come up with some scenarios with visuals, I'll have to for
the ievobio talk anyway.
