To start with, have a look at the queries listed here:

http://www.isb-sib.ch/~ejain/expasy4j-webng/query.html

If your system can handle GROUP BY, this opens up a lot of possibilities, e.g.:

- Number of proteins by organism.
- What is the most frequently cited paper?
- Who is the most frequently cited author?
- What databases do we reference, and how often?

Some quick questions:

- Do you support boolean operators apart from AND?
- Can you do optional matching (e.g. return the rdfs:label value, if present)?
- Do you support '<' and '>'? On dates?
- Transitivity is really important. How is this implemented? Do you 
actually generate and store the inferred triples?

I'm also interested if you found any aspects of our data difficult to deal 
with. (Apart from the size :-)
