i don't know what you mean specifically by "object database", but we
use hibernate to map our object model to a relational database.

our challenges are 1) add concepts like stamping and tags to our
object model; 2) map them to the database to preserve performant
queries and efficient storage; 3) make our object model as natural as
possible for our apps and protocols to work with.
