Topics

(1) Memory Management

• Large Image Handling
• Streaming
• Out of core data management (memory mapped files)
• Decide on smartpointers e.g. C++0x/Boost

(2) Migrate some code to the repository (e.g. Qt widgets) and use it in our respective toolkits

Steve: goal to make some progress on consolidating some Qt widgets from our various projects into a repository that we can all contribute to.

(3) DICOM IO layer on top of DCMTK: interpretation of DICOM data

• David Gobbi's CMake/VTK wrappers for DCMTK
• Delft project includes DCMTK

(4) Interoperability of plugins

Steve: Summarize what would it take to make a standard that could handle at least the three following systems:

• Slicer Command Line Execution Model
• XIP / DICOM WG23 Application Hosting
• MIPAV/JIST plugins

If we can handle those, then that's probably broad enough to cover many common scenarios.

Jc: PythonQt and the Qt based plugin architecture used in SlicerQt

Sascha, Olivier: Generic service oriented approach to expose modules for multiple platforms.

(5) Generic event mechanism (e.g. event bus, translate events into signals)
