In fact my main troubles have been performance troubles. That may be
because I'm not an experienced PHP developer, or because I have missed
other things, but I had to do a lot of tricks to get all this to
run.

The main reason why my queries take a long time to execute, is because
they all involve the ontology. So if I ask for resources of a certain
class, I also want the resources that belong to subclasses of this
class, and to subclasses of those classes. What seems like a simple
query often turns out to need multiple levels of recursion.

As a user, I would certainly appreciate this. For one thing, it is
easier to decide to sit down and learn how to use a tool once you know
it is used in several respected institutions. And then, we might learn
something from each other. I would be very willing to share my code.

All the best,
Peter
