(Moving this discussion to the public mailing list)

To follow up the teleconference we just had...
Here is an example of finding links between DBpedia receptors and the IUPHAR 
receptor table:

* Look at http://dbpedia.org/resource/GABAB_receptor
* Look at property http://dbpedia.org/ontology/uniprot  it has the values 
"O75899" and "Q9UBS5"
* Now look at the IUPHAR "Class C" spreadsheet
* You will find these exact identifiers in the "Human nucleotide" and "Human 
SwissProt" columns of the matching IUPHAR entry, respectively (that should 
be columns 8 and 10, if I counted right).

-> Mapping accomplished!

Note that only some of the receptors mentioned in 
can be mapped to IUPHAR with this procedure (not all receptors have sequence 
entries, because they are multimeric complexes). But for those entities 
where it works, we can create a federated query that spans NeuronDB (OWL 
file), DBpedia (SPARQL endpoint), IUPHAR (direct query of relational tables 
/ CSV), PDSP KiDB (OWL generated from CSV) and others -- quite useful and a 
good show case for query federation.

Hope that helps,
Matthias Samwald
