Innovation – in numerous spheres, but especially in the economic – is one of the key putative benefits of Open Data. However, innovation is a complex and rarely solo activity.
Multiple inputs are required to create new products, services or efficiencies. It’s therefore unsurprising that ‘user innovation communities’ are visible all over. 
In my research, I’ve been looking at communities with proven innovation records – those of open source software – to identify exactly what activities are taking place that enable innovation.
