> Questions that you might want to ask <

What is it?

This is a network analysis of the Code. All the elements of the Code (Articles, Recommendations, Examples, Glossary Items) are interconnected according to their direct and indirect connections. After the network is created, some structural layouts are applied to depict its structure.

How can I use it?

You could click on the links above for the different versions. The first two links (marked with Online and Offline) contains the exported network with the Force Atlas 2 layout. The user can navigate through the network, but cannot make any changes. The last link (marked with Gephi) is the original network to be opened with Gephi. There the user can enjoy the full capabilities of the network.

Please read the manuscript and especially the supplements for further information.

What shall I do if I discover any problems, malfunctions, errors, etc.?

Please report them to me by email (This email address is being protected from spambots. You need JavaScript enabled to view it.). I will do my best to fix them.

Can I edit the network?

Of course!

I would encourage users to try to further develop this effort, correct mistakes and try different things and layouts. As I am planning to regularly release updates, if you do so, however, please inform me. In case you have made a significant update or change, your version could be hosted here.

Also, I am open to any kind of collaboration and further development. So please do not hesitate to contact me!

If I have questions?

If there are software-related please refer to the appropriate sources. The Gephi and Sigma communities are quite open and active, and host wonderful tutorials and forums.

For anything else, please do not hesitate to email me and I will do my best to respond.

May the Code be with you…
