To create a Schema (smart contract) on a blockchain, supply a name, a short description, the schema specification itself, the wallet to be the owner of the schema, and optionally include meta parameters to link the Schema with external data.

A created Schema, which must comply with the [JSON Schema](http://json-schema.org/) standard, is a template that all future Records created with the Schema must comply with.

Note that once a Schema is created, the "specification" and the "wallet" parameters can no longer be updated. Also note that chain and contract parameters are automatically assigned to a created Schema.

| expand       | string    | No       | Comma separated list of parameters to expand [wallet, chain, contract, assuror] |
| name         | string    | Yes      | A name for the schema |
