I’ve been working with Jekyll RDF to turn a similar project into a web app. It basically lets your run SPARQL queries (among other things) as part of page templates, then output the whole as a static site. I’ve integrated the front and back ends locally (so I know it works), and am in the process of designing and building the UI (ideally by the end of the year). I’ve attached a quick walkthrough of the wireframe clickthrough prototype to date. Something like this might be a way to help us think about putting together an application collaboratively.
