Hi Sean, Arggggh... Maybe I can propose a change to the namespace semantics in my project. I've been given the following brief. Data files should have a logical namespace structure which can be globally unified across multiple instruments and receiver platforms into a common namespace on the filesystem. I have a whole list of other data representation constraints and Avro satisfies them all. This one is the only 'issue'. Thanks for your help.
