Why Modularization

Modularization is a common design answer to the problem of managing complexity and growth.

From the Linux Kernel: http://www.ibm.com/developerworks/linux/library/l-lkm/index.html?ca=dgr-lnxw07LinuxLKM&S_TACT=105AGX59&S_CMP=GR

to KDE: https://wiki.archlinux.org/index.php/KDE_Packages#Terminology

to Qt: http://labs.qt.nokia.com/2010/10/26/qt-is-going-modular/ http://labs.qt.nokia.com/2011/01/21/status-of-qt-modularization/

Details on the goals of modularization were presented here: http://www.itk.org/Wiki/ITK_Release_4/Modularization/Tcon-2010-12-03 In particular in: http://www.itk.org/Wiki/images/1/16/ITKv4-Modularization-2010-12-03.odp http://www.itk.org/Wiki/images/7/75/ITKv4-Modularization-2010-12-03.pdf

Main Goals of Modularization

1) Find / label / remove the trash in ITK.

2) Organize the ~2,330 files into conceptual cohesive groups.

3) Test and label each group according to measures of quality control : Code coverage, correctness, style, dynamic testing, documentation...

4) Raise the quality bar for critical components. For example, the itkObject must have 100% code coverage, while we could live with the Blox classes having 30%.

5) Maintain that level of quality as more code is added to the toolkit.

6) Facilitate the use of add-ons with ITK (External and Remote Modules) without having to include them in the toolkit.
