HYDROGEN is not a part of the ARGON abstract specification - it's actually an implementation component. No ARGON user code will depend upon HYDROGEN, but the implementation of certain parts of ARGON itself will.

HYDROGEN is a hardware abstraction layer; the core abstraction of the underlying node, from which my first ARGON implementation will build. The node resources HYDROGEN must provide a portable interface to are:

I've written a good series of blog posts on HYDROGEN:

• Introduction
• Code generation
• Extensibility
• The boot process
• Device drivers
• Implementation
• Conclusion

Also, the draft specification is available in DocBook format from ARGON subversion.
