My books and google-search show only basic-mapping and promise me
that hibernate is powerfull enough to do more complex-mapping as described below, but how?

Because the final model isn't known yet, the application doesn't use JavaClasses directly to model for example
'Cat's and 'Dog's, but uses meta-elements instead such as the Java-classes MetaClass, MetaAttribute, etc.
With the basic-mappings the database would contain only a few tables, the one for the above meta-java-classes.
But with this method apples and oranges would be mixed in the database in only 1 metaclasses-table.
Instead the desired mapping should map the single java-class MetaClass to different tables, depending on
the attributes (for example MetaClass.classname).

Is this possible with hibernate?

Maybe I don't have the right terms to search for, and need any help such as literature, examples or experiences.
