Hi Kei,

Great to hear from you and the podcast idea is excellent. I wonder, is  
there any effort to have semantics attached to the podcasts? That'd be  
cool to have triples indicating content.

The main difficulty with making an iPhone app work with multiple  
SPARQL endpoints, from my perspective, is due to 1) differing coverage  
and content, 2) differing structures, and 3) differing URIs. Number 3  
is the easiest to deal with.

An application that goes straight to the endpoints without using a  
server to do translation, aggregation, etc. across endpoints must  
either do all of this itself (too much for an iPhone app) or get its  
full content  from the endpoint it uses.

Detailed PubMed information, for instance, is a very important feature  
to scientists. Only the Bio2RDF endpoints provide details including  
abstracts in RDF. All endpoints seem to have the authors associated  
with a particular paper but a big limitation of every endpoint is that  
it is impossible to reconstruct the order of the authors. (At least I  
haven't found a way.)
