question

What you're looking for is effectively a User Generated Content service, which we do not provide yet (but see below). Our data systems, broadly speaking, fall into two categories: Data which needs to be readable by all users is sharded and cached, so that it can be efficiently read by everyone, but which is infrequently updated by the title owner (such as Title Data), and data which needs to be frequently updated by the player, but which will only be accessed by that player or, at most, that player and a few others at a time (such as User Data and Shared Group Data).

Currently, our Content service could provide you with a way to do this, but you would need to have a custom game server which manages the writes to the data store (preferably with some additional checks on the data being sent), and an external data table which you would use to manage any metadata you need concerning the levels (most recent, any voting, reporting for infringing/offensive content, etc.).

In addition, if your title is still at least a few months from its ship date, we are planning on providing additional options for storage of custom data in a more flexible manner. So if you're still a ways out, please keep an eye on our announcement and blog pages, as we'll be providing more details of that in Q1.
