What is a schema?

A schema describes the structure of data. It is a set of rules that defines what data are required, what data are optional, and what the data types are. A schema is used to validate data and to inform data consumers how they can use the data.

m2c2kit uses a subset of JSON Schema to describe:

• The configurable game parameters that customize how the assessment is administered.
• The data that are generated by each trial in the assessment.

Each assessment has unique schema for its game parameters and trial data.

Refer to the section on Schemas in the tutorial for how to use schemas in your assessment.
