Summary0001927: Add "Slicer Data Bundle" read/write to .mrb (zip) files
Description

While slicer has traditionally used .mrml (xml) files to point to data stored in a collection of files in arbitrary locations (or even urls) for some use cases this is a burden and it would be preferable to have a single file that encapsulates an entire document.

Additional Information

The proposal here is to create a new format called a 'medical reality bundle' that is a .zip file containing a scene.mrml file and all the data it points to.

The application logic currently has support for creating the self-contained

const char vtkMRMLApplicationLogic::SaveSceneToSlicerDataBundleDirectory(const char sdbDir, vtkImageData *screenShot)

http://viewvc.slicer.org/viewvc.cgi/Slicer4?view=revision&revision=17927

However these are not yet saved as a single file. The goal here is to use libarchive to create a file in zip format containing the results of this method (with a unique .mrb file extension so slicer can recognize them in the future).

TagsNo tags attached.

Note that in order to implement this we'll need to upgrade the version of libarchive on all platforms since writing zip files was only added in newer versions of libarchive (>3).

From the notes in the superbuild file it seems that version 3.0.3 works on all platforms.

Nicole has done most of the libarchive logic in this method:

const char vtkMRMLApplicationLogic::Zip(const char zipFileName, const char tempDir, vtkImageData screenShot)

But there is also now some "vtkArchive" which isn't really a vtk class, but instead is just a library with a single function. I plan to move the zip writing and reading helper functions into the vtkArchive file for easier re-use.
