We have committed to [[ https://www.mediawiki.org/wiki/Wikimedia_Engineering/2014-15_Goals#Engineering_Community | release a Developer Hub prototype during this quarter ]]. Work in progress: http://juliuszgonera.com/wddh/
This prototype must have a homepage and three APIs documented and showcased. It must implement the structure and look&feel desired.
An API sandbox should be available, either integrated to the prototype or working as a stand-alone proof of concept.
This prototype can be based on any tool helping to build this prototype fast. We might or might not use this tool for the final project.
