I recently spent a day working with my colleague Jun Zhao to successfully implement a Shuffl card containing a FlyUI (http://code.google.com/p/flyui/) gene finder widget.
This achievement is an important confidence builder, as it further demonstrates the power and flexibility of the Shuffl card plugin model: we were able to embed quite complex FlyUI widget logic unmodified into a Shuffl card. The FlyUI widgets are built using the Yahoo YUI libraries, so this success also demonstrates that Shuffl (based on jQuery) can coexist with YUI code.
The remaining challenge is to find easy ways to deploy such applications. To overcome the Browsers' "same origin" restriction on Ajax calls, the Shuffl+GeneFinder application was deployed via an Apache server configured to redirect and proxy requests to the SPARQL endpoint for FlyBase data hosted at OpenFlydata.org. In this, Shuffl is playing out quite nicely as a flexible user interface toolkit for application developers, but it is not yet clear how to deploy Shuffl as a general purpose, user-configurable data viewing and annotation tool. Maybe we should think about deploying a Shuffl application server? Could Google Apps, or similar, be recruited for this purpose?
