This is the place to collect thought for the future of egroupware

motivation / overall goals

- Get rid of massive session overhead
- performance
- stability
- codeability
- usability

design constrains

eGW 1.x codeline	eGW 2 codeline
HTML GUI	JS GUI
nothing	exception management
tight coupled layers	loose coupled objects (data, persistency, properties ...)
various entry points	single entry point (dispatcher / handler)
almost nothing	interfaces, abstract base classes all over eGW (everything is an object)
no / own patterns	standart patterns like singleton / factory ...
adodb	pdo
much own stuff	framework like eZC or Zend
homebrew UI's	Usability enhanced / improoved UIs
nothing	concurency management
nothing	unit-testing

migration / way to go

soft migration

• define milestones
  • Choose framework(s)
  • Adapt egwapi
  • app_skeleton - Whatever the directory structure works out to, we can save ourselves some effort by putting in a minimal structure
  • addressbook - It's becoming integral to everything, and makes a really good example for the rest of us to follow.
  • new Code Corner - The current one has helped out so much
• fast release cycles

start second codeline

• allways upgrade from 1.x to 2 possible
• customers can switch when 2x codeline sweets there need

Frameworks / Components

The question ezc / Zend / Pear is not necessary an "or" question, as components can be combined from different sources. However some core decisions must be taken: Error Handling / Autoloading / Directory Structure / ..?
