Wiki Tree Layout

From NESG Wiki
Jump to navigation Jump to search

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
