Step #1 : Scala DSL for Datomic Schema

Original Clojure Schema

[
 ;; person

 {:db/id #db/id[:db.part/db]
  :db/ident :person/name
  :db/valueType :db.type/string
  :db/cardinality :db.cardinality/one
  :db/fulltext true
  :db/doc "A unique person name"
  :db.install/_attribute :db.part/db}

 {:db/id #db/id[:db.part/db]
  :db/ident :person/character
  :db/valueType :db.type/string
  :db/cardinality :db.cardinality/many
  :db/doc "Traits of character"
  :db.install/_attribute :db.part/db}

 [:db/add #db/id[:db.part/user] :db/ident :person.character/stupid]
 [:db/add #db/id[:db.part/user] :db/ident :person.character/clever]
 [:db/add #db/id[:db.part/user] :db/ident :person.character/dumb]
 [:db/add #db/id[:db.part/user] :db/ident :person.character/violent]
 [:db/add #db/id[:db.part/user] :db/ident :person.character/weak]
]
