@csell5 what does this mean?

[theClarkSell]

it was meant to help us define the schema\doc version in the datastore such that if we need to build in some migrations we have a mechanism of which to apply the appropriate updates as they are accessed. We don't have any migrations in play at all but something we should think about designing, especially if we move to fauna or whatever.
