JSON Schemas
The metadata schemas are available below using json schemas (see http://json-schema.org/), described as “a vocabulary that allows you to annotate and validate JSON documents.”
JSON schema provides a relatively simple way to define precisely what elements are required, add any additional constraints on element values (beyond basic JSON type), add descriptions to elements, distinguish required and optional properties, define default values, etc. It enforces a more rigorous approach to the definition of the JSON file, and can also be used to validate files against the specified structure.
To provide a more accurate description of the files used in the MDR system, therefore, JSON schema descriptions were developed for the two main files. Those schemas are available at:
