in case you didn't find it naturally.


It's ZPL, by the way. It supports monadic, dyadic and triadic types of relations; the triadic ones are mainly used to create relations in a given context. It is designed to be scalable and fast, since it is used to render pages and a same page may easily involve 50 or 100 relations. All relations are indexed, so basically a query involves looking up a single key in a OOBTree. Complex queries similar to catalog queries are not supported, for performance reasons, but there is some flexibility for creating complex predicates.
