Re: [Bigdata-developers] Journal compatibility 1.5.3 vs 2.0.0

[Bryan T. <br...@sy...>]

Yes.  It is actually if you create a namespace with a newer vocabulary,
then you can not open it with a classpath that does not include that
vocabulary.  Since 2.0 uses a new vocabulary declaration by default, create
your namespace in 1.5.3 if you want to use it in both 2.0 and 1.5.3.

Thanks,
Bryan
