For serialization it seems like you'd probably want to start with STON as its
format is simplest and then if you need more than a zipped STON file you
could pursue other options. There are a messagepack and thrift serializers
too. I think STON cannot serialize contexts, and maybe some other things.
I think the limitations are well documented.
