Same here. I've done a project with Versant five years ago and we were badly
hit by the decision of the database vendor to give up a special language 
binding - just as
we had finished the project. For that reason I would never ever do a 
project again
with oodbms - no standard, no way of switching the database product.

The problem is, that the ODMG group is so much influenced now by the 
Java hype, that
nobody seems to expect, that the ODMG 3.0 standard seems to be a real thing.

Another view about comp.databases.objects shows us, that the Java world 
produces
one new oodbms each week and they do not care about any standards. Their
standard is Java and the rest of the world is meaningless.
