For the provinces of Brabant and Friesland my company (Delving) has deployed our open source cultural heritage software infrastructure, and we recently built an application for gathering data from online contributors. The focus is on Historical Societies (Heemkundekringen) which made it an excellent usability challenge (these are older people). AngularJS revolutionized our development, because it's the first Javascript framework which made great sense to me, a dyed-in-the-wool Java coder from way back. I would like to give demonstrations and code walk-throughs and give feedback on how it was done.
