Tiny helper lib, to keep datomic schema more concise without any restraints

Why

Datomic is extremely powerful but many try to put business logic into the datomic schema definition.. Check out: https://en.wikipedia.org/wiki/Conceptual_schema https://en.wikipedia.org/wiki/Logical_data_model https://en.wikipedia.org/wiki/Physical_data_model

I also tend to make transaction/db functions even if its not necessary for atomicity, just to explain business logic.

I believe the datomic schema should be pure functional and effective! And you should abstract business/application logic in a other place then the datomic schema!

So the goal is to be able to create concise schema parts which you can easy read over, without limiting any of datomic powers

Example

(def user
  {:user/name [:string :unique-value]
   :user/role [:ref :many]
   :user/whatever [<:valueType> :<optionalAttribute>]})
   
(build-schema user)

TODO

• tests
• clean up validation (super ugly working version right now)
• split functions into smaller parts and make it more readable|easier to understand
• renaming
• documentation
• example
• getting high value input for improvements!
• WIKI how and why you should do thing a certain way (best practices)
