OCF核心规范分为一组文件:
-核心规范（本文件）:核心规范文件规定了框架，即OCF核心架构、接口、协议和服务，以实现物联网（IoT）用途和生态系统的OCF配置文件实施。本文件对所有设备都是强制性的
-核心可选规范:核心可选规范文件指定了框架，即OCF核心架构、接口、协议和服务，以支持OCF配置文件在物联网（IoT）使用和生态系统中的实现，可以选择由任何设备实现
-核心扩展规范: Core extension specification（核心扩展规范）文件规定了可选的OCF核心功能，这些功能在范围上非常重要（例如，Wi-Fi轻松设置、云计算）。

The OCF Core specifications are divided into a set of documents:
- Core specification (this document): The Core specification document specifies the Framework, i.e., the OCF core architecture, interfaces, protocols and services to enable OCF profiles implementation for Internet of Things (IoT) usages and ecosystems. This document is mandatory for all Devices to implement.
- Core optional specification: The Core optional specification document specifies the Framework, i.e., the OCF core architecture, interfaces, protocols and services to enable OCF profiles implementation for Internet of Things (IoT) usages and ecosystems that can optionally be implemented by any Device.
- Core extension specification(s): The Core extension specification(s) document(s) specifies optional OCF Core functionality that are significant in scope (e.g., Wi-Fi easy setup, Cloud).
