Personal Knowledge Network

We have set up a complex tag system based on the rainbow framework. It includes cities, the area of sustainability and articles. All the information on the website will be classified by the tag system. The system will make different sustainable events to be focused and paid attention to. Your knowledge network will be built via that.  

There are two approaches to use our tag system:

One is to mark tags for articles when you’re publishing them.

The other approach to use the system is to mark tags for articles while you’re looking though them.
