First MBE version out
MBE is a backend written in Python 3 that provides database access, authentication, access control and other features on top of the MongoDB document database.
It is basically a blatant attempt of having the cake and eating it, to explore the possibilities given when combining the absolute freedom of a document database with the fine-grained control of a JSON Schema.
It doesn't hurt, of course that the same JSON-schema can be used to validate data directly in the web client interface, for example using angular-schema-form.
