The Vortex is made up of nodes - separate HTML files. The node name is the internal identifier for the file; it can be up to 16 characters long, can contain letters and numbers, is case-sensitive (since we're running on Linux) and will show up in the node's URL.

Example: creating a node named 'Clouds' would produce a file named 'Clouds.html' at the URL http://deekoo.net/technocracy/vortex/nodes/Clouds.html

The nodename is also used when calling up the node for editing.

Nodenames could be called filenames, but that would be too logical and slightly inaccurate.
