"ozone does not introduce a new type system, object or computation model like
relational DBMSs and ODMG/OQL does. ozone just lets you work with persistent
Java objects in a transactional environment. ozone is Java! No other types than
Java types, no other query/update language than Java, no impedance mismatch!"

In other words: Java is the "native" query language of ozone.

However, a descriptive query lang could be of benefit even for an OODBMS. But
IMHO such a query lang should provide a real OO interface (in contrast to OQL,
which introduces all the problems of SQL and adds some new ones). There was a
discussion about S.O.D.A. (Simple Object Database Access: real OO query system)
here on the list but unfortunately we stuck with this effort.
