Building a second brain with Zettelkasten

I am starting to play with the idea of moving all my organization, notes, sketches, to-do's to a single application by following the Zettelkasten Method as personal knowledge management.

The main idea is that this organization lasts a lifetime, independently of any platform and application. Just basic pen and paper was enough for Niklas Luhmann, a social scientist, to publish 50 Books and over 600 articles.

The ideas resemble pretty much how Wikipedia is structured, closer to a Web. All articles link to other links and are intertwined.

Principles

A few principles I get from the article Zettelkasten — How One German Scholar Was So Freakishly Productive are:

• Atomicity
• Autonomy
• Connection between notes
• Using tags instead of categories
• Use your own words and keep it simple
• Never delete anything
• Link Reference pages to connect all the dots, like maps

Writing down the notes

Taking notes to go via:

1. Fleeting notes: ideas, quotes, references, links, images.
2. Literature notes extractions from books and papers.

Processing the notes permanently:

1. Permanent notes: writing with your own words in a way that you will understand in 10 years forward.
2. Index notes: hyperlinks with notes nodes and mapping.
3. Keyword notes: Tags list
