But what does a query consist of? Can it cross links? Links between
documents? Multiended XLinks or HyTime links? 

Also, you say that SIM is good at "data, not objects." By data do you mean
only textual data? Could you characterize the data it is best at handling?

I don't think ODB performance is there yet, but the text storage people
aren't the only ones who need it so I expect it will be someday.
