#### "Schema"

Một "schema" là một định nghĩa hoặc mô tả thứ gì đó. Không phải code triển khai của nó, nhưng chỉ là một bản mô tả trừu tượng.

#### API "schema"

Trong trường hợp này, <a href="https://github.com/OAI/OpenAPI-Specification" class="external-link" target="_blank">OpenAPI</a> là một bản mô tả bắt buộc cơ chế định nghĩa API của bạn.
