Wiki Tree Layout

This outline of the NESG NMR Wiki is designed to expand on the existing "Master Recipe" and should serve as an experience harvesting tool.

• It has a rather broad coverage to facilitate long-tewrm growth and development. Aditional compact aggregator pages may be needed to pesent specific information concisely.
• There would be separate webs within the wiki: Public(or Main), NESG, and member lab webs. Most common knowlege topics should be public, unless they are specific to NESG
• We assume that the target audience has some knowledge about NMR and protein structure determination, but make the content useful for training
• "Resonance Assignment" and "Structure Determination" chaptes would focus on individual software packages. The XEASY resonance assignment tree, as the most complete, would serve as a template for other software.
• Most chapters should include a "general principles" section.

Here are two comments from Guy:

- need to have centralized site for downloading all software that NESG has developed or licensed; this would be a central site for NESG scientists to use to access the latest version of all software

- need to allow outside users to access links to all software (they will need licenses to download) and also to download software from NESG
