Mindey, 
Homepage 2.0
This would be a personal open-source system to connect all one's accessible web data into a usable semantic network and a language to access it all.
Homepage 2.0 would be a website made of 3 major components:
- Daemons on personal devices like computers, phones, cars and other smart devices accessible to user, making data from various apps to which the user is logged onto available to the owner.
- Local version of the website for editing and writing content conveniently, and producing markdown files with associated static files retrieved from daemons while editing.
- Remote version of the website for sharing that data with others, implementing the access permissions based on social identities.
When user is typing (WYSIWYG), the user is automatically accessing the various device apps for data s/he needs as autosuggest to compose text (e.g., Gmail messages, Calendar events, etc. etc.). When user finishes writing a post, the user simply pushes the content to remote server.

我猜想，這種守護程序只能與那些爲系統上其他應用程序提供本地API的電話或計算機應用程序一起使用。並非所有應用程序都需要此功能。如果應用程序具有公共API，則無需查詢設備以獲取信息。
設備守護程序僅可用於訪問其他不可用的內容，例如，不提供公共API的應用，系統上的內容（例如手機上的照片），這些內容不會上傳到任何雲服務。
I guess, such daemon could only work with those phone or computer apps, which provide a local API to other applications on the system. Not all apps might need this. If an app has a public API, no need to query the device for information.
The device daemons could only be useful for accessing things not available otherwise, e.g., apps that don't provide public API, things on the system like photos on the phone, which are not uploaded to any cloud services.
