<h3>Objective</h3>
* Review the state of the art in medical imaging web apps
** Follow on from the [http://qiicr.org/web/outreach/MIWS-hackfest/ MIWS Hackfest at BWH].
** Discuss subsequent developments and ideas
* Consider various use cases:
** Pure web browser application
** Web browser + remote compute or rendering services
** Web App widgets used in desktop application (e.g. via QtWebKit/QtWebEngine in Slicer/MITK/MeVis)
* Topics
** Native JavaScript code for DICOM IO, Rendering, Processing
** Organization of toolkits and libraries
** Interacting with the community of like-minded developers

<h3>Approach, Plan</h3>
* Discuss recent developments cited in the Objective section
* Identify more valuable development priorities
** provide useful functionality (e.g. improved DICOM patient/study/series/search browser)
** probe any outstanding issues (e.g. test scalability or performance questions)
** establish paradigms for ongoing development
* Finalize a prototype showing JS-C++ interaction replacing the CTK DICOM Browser Widget with a web-technology based implementation

* Experimental integration of ipfs-hosted data with CTest based continuous integration (WIP) https://github.com/QIICR/dcmqi/pull/22
* Identified [http://www.zerorpc.io zerorpc] as a powerful solution for distributed MIC apps (based on [http://zeromq.org ØMQ] and [http://msgpack.org MessagePack]).
** Use [https://pypi.python.org/pypi/msgpack-numpy msgpack-numpy] to support ndarrays in zerorpc (implemented via monkey-patching).
* The JS-C++ interaction lives now on an [https://github.com/nolden/CTK/tree/wip-dicom-web experimental branch in CTK] (will move to the commontk organization soon)
** various mechanisms for development, debug and deployment can be tested, 
*** Qt resource compiler
*** separate HTML files
*** running the UI in a browser vs integrated in the CTK application, remote debugging of javascript (all accessible through buttons in the UI)
