將數據儲存到⾮非開放的 IoT 雲服務，是否能「取回」⾃自已的資料，會是⼀一個問題。儲存在真正開放的IoT 雲，才能解決這樣的問題。開放式 IoT 架構的意義，必須是⾃自由的：Personal Things

Libre Software

Gives users the freedom to run the software for any purpose as well as to study, modify, and distribute the original software and the adapted versions.

「物聯網裝置終將免費」。在IoT Open Architecture 的理想中，消費者可以免費取得硬件。這個理想並⾮非不可⾏行，第⼀一個步驟，就是設法降低取得硬件的成本。⾃自造硬體（成為IoT 的創客），就是重要的起步

REST model for small devices !Like HTTP, CoAP is based on the wildly successful REST model: Servers make resources available under a URL, and clients access these resources using methods such as GET, PUT, POST, and DELETE.

http://coap.technology


Made for billions of nodes !The Internet of Things will need billions of nodes, many of which will need to be inexpensive. CoAP has been designed to work on microcontrollers with as low as 10 KiB of RAM and 100 KiB of code space (RFC 7228).



Existing skills transfer !From a developer point of view, CoAP feels very much like HTTP. Obtaining a value from a sensor is not much different from obtaining a value from a Web API.



Ready for integration !Since HTTP and CoAP share the REST model, they can easily be connected using application-agnostic cross-protocol proxies. A Web client may not even notice that it just accessed a sensor resource!
