What is the tool for assisting group knowledge

 Most of our power of group knowledge from symbol and protocol of transmit it.

History of symbols.

First  Drawings

2nd , it simplified to symbols.

3rd , complex of symbols are grammar.

History of currency

1st there are Goods.

2nd.  Some goods regarded as it can save credit long time.: Saving function.

3rd. These goods can transmit credit and benefit. :Exchange function. Transmit function.

Exchanging is count credit with number.

Mathematical expression has the least width of recognition than the other protocols.

Translating credit that expressed by natural launguages into number is expanding area of business communication. 

2nd and 3rd is replacable.

Currency is current of energy. Currency provides the tightest connection between emotion and symbols with narrow interpretation width. But now currency can not handle all information.

Photoshop, DTM, vocaliod, Contents management systems provide better symbols manipulation. I call them CMS.

Ultimate group knowledge tool is manipulating all information as currency.
Giving major 3 function to all information on integrated CMS is most effective direction of  effort.
