A few weeks ago, in September, the Open Knowledge Festival brought together a world-wide community of people working on all sorts of "open": open cities, open design, open government, open science, open hardware, open education, ... and of course: open development.
As one of the main topic streams, the open development track was packed with presentations, discussions, panels, workshops and a hackathon.
From a business case perspective: how can a "business intelligence" approach help in data processing and analysis, based on performance indicators.
From a technical perspective: how can we deal with the large variety and volume of the data and documents.
From an information perspective: how can we combine a variety of structured and unstructured information for various purposes.
Michiel has put all of this together in a proof of concept "platform for business intelligence" based on CouchDB, using OpenCalais to annotate documents and with a front-end based on Exhibit and Simile.
