datomic noob question: I see that the tutorials suggest only using :db.part/user for experiments, and presumably making other partitions for real work - all the examples for enumerated type entities use the :db.part/user partition even after saying we shouldn't use it - and when I make a schema that creates a new partition, my #db/id[:db.part/other-partition] ids cause an error

what's the right way to do this?

fwiw I'm using conformity and have a norm-map with one item containing the partition, and another containing everything else, with a :requires pointing back to the partition item
