It's an unliftable curse!

ooops... [1] was supposed to point to http://data.semanticweb.org/documentation/user/faq#how_to_add

You are absolutely ok to mint URIs in the dogfood namespace, as long  
as we manage to get the data into the site afterwards! The easiest way  
might be to produce the XML files as outlined in [1] (this time the  
link is really there! ;), but we should also manage to get it to work  
by adding the right triples in your RDFa. I should write up a list of  
triples that are necessary for the dogfood UI to make sense of the  
data - everything can be loaded, but not everything displays nicely at  
the moment.

Very cool.

I just asked Daniel Schwabe if he knew if we could repeat the process  
from last year (take EasyChair data, convert with our script) for the  
main conference data. Let's see what comes out of that. I don't know  
anything about the workshops, though. I'd say there are three  
possibilities at the moment (in increasing order of effort involved):

1.) If you use EasyChair, take the data from there and convert with  
existing script. You need access to the XML output of EasyChair, though.
2.) send me the data in XML as per [1], so that I can convert it with  
the same script.
3.) generate the RDF yourself. That will probably need some iterations  
to get it right (or I will have to make the dogfood URI more robust!)

ouch, you spotted my vocabulary hacking there... those two properties  
are additions I came up with, which are unfortunately not yet  
reflected in the vocabulary source online. I'll correct that asap.

Cheers,
Knud
