Since the jToolkit is not under active development anymore, it is necessary to move Pootle to a modern web framework.

• Overview of current python web frameworks
• TurboGears
• Django

• serving web sites
  • templates
  • session management
• handling of preferences
• spell checking (historically)
• sending mails
• time based caching
• file locking
• some tests

• new testing framework (probably rewrite; maybe based on python unittest and Twill)
• integrate a new spell checker
• move non-core features to the translate-toolkit (e.g. merging translations from different sources)
• user preferences (probably connected to the openid project; maybe based on ConfigObj)
• server configuration (maybe with ConfigObj):
  • properties of projects and languages
  • descriptions
  • file locations, …
• web server / application server:
  • page generation (e.g. using kid)
  • authentication (probably done with openid in separate project)
  • session management (language negotiation, cookies, …)
  • mime types
  • url handling

• the migration of the web server to another framework seems to be the biggest single task - it should be hard to do this incrementally (if that is necessary)
• the inter-dependence of the openid project and the framework migration increases the complexity
