SelfKey JSON Schema

SelfKey JSON Schema

In order to solve certain issues around the area of data harmonization and compatibility regarding the management of data and documents using the SelfKey Identity Wallet and the transfer of data with 3rd party integrators, SelfKey has developed a JSON Schema to manage requested data formatting. The schema is available at http://platform.selfkey.org/schema
