ODCS Python SDK

[RyanBacastow]

Unsure if this is covered already but I've set about to the task of creating an sdk as I refine a contract system based on the ODCS and I think it might be worth also including as a ride along component to the code repo. Essentially if the contract is our API, we naturally should be able to author contracts more easily by creating an SDK around the API. Something like an ODCS frontend could then be built relatively simply calling the SDK methods/classes. The classes would be broken out into sections much like the contract itself (the sdk should be a mirror of the API in as many ways as possible).

A DataContract base sdk class might include the following methods:

• read_contract_from_yaml_file(self, file_path) -> dict
• read_contract_from_json_file(self, json) -> dict
• validate_contract(self, contract_contents, version) -> bool # would validate known required fields are present based on version specified
• create_new_base_contract(self, contract_name) -> dict
• create_contract_as_yaml(self) -> str (valid yaml)
• create_contract_as_json(self) -> str (valid json)
• save_contract_as_yaml(self, outpath) -> None
• save_contract_as_json(self, outpath) -> None

Then as mentioned some other classes might be things such as Metadata, Dataset, Stakeholders, Roles, etc.

I can provide a base/sample python file implementing the class/sdk if that's of interest.
