+A Schema stands for the description of serialization instances(string/stream/file/...) and has two properties. First, it is also in the format of serialization type. Second, it defines what requirements such serialized instances should satisfy.
Besides describing a serialization instance, a Schema may also be used for validating whether an instance is legitimate. The reason is that it defines the ```type```(and other properties) of a serialized instance and inside keys. Taking JSON Schema for example, it could not only be referred when describing a JSON string, but also be used for validating whether a string satisfies properties defined in the schema[[1]](#References).
