Creating and Modelling Validations
OpenSABER validates any record that is inserted or updated in the Registry is validated. Each field in the incoming record is validated using JSON Schema mechanism. The validator we use supports draft 07 of the JSON Schema specificiation.
OpenSABER uses Everit Schema validator for validation. The schema file needs to be created and pre-deployed in the registry under src\main\resources. You can take a look at these examples pre-built into the registry for reference purposes and you may add your own.
The following reference sample schemas can be found here
To quickly understand these schema files in detail, we suggest you take a look at this README of Everit validator.
For more details, look at validation specification
For a quick and easy schema generation, supply an example payload to this online schema generator and it will create a rough schema for you.
You can additionally decorate the schema specific to OpenSABER in the following way. This can be found in the reference example - Teacher schema
