Relations in RDF

Hi Scott, All,

I was wondering what the general take is on predicates in RDF 
representations used by the HCLS group. I've been looking at our RDF 
model for Gene Expression Atlas at EBI and presently I'm using the same 
"is_about" relation for a lot of the predicates as this is the lowest 
level of constraint from the OBO Foundry folks for some of these 
information relations. Alan Ruttenberg tells me that empirical evidence 
suggests that using a larger number of relationships correlates to 
poorer ontologies. However, I've also been told from various RDF 
advocates that having more granular level predicates is useful for 
querying. Are there any thoughts from the group on this? I have no 
preconceptions here (I have no reason to disbelieve Alan or the RDF 
folks) so open to thoughts and suggestions.

Cheers,

James
