The readme is a bit short. In the docs are the actual requirements for the "OpenGrid Service":
A web server for hosting User Interface application
An Java EE application server for deploying service layer (the service template implementation has been tested with JBoss EAP 6.2)
MongoDB version 3.0.6 for storing data and template service layer configuration
Man, I know mongo has some geolocation tools but I would really like to see this with a better database. Good on Chicago for doing a professional job releasing this software though!
