With software, technology makes it easier to track, but not reward. We cannot separate papers, data and software when we release research. http://openresearchsoftware.metajnl.com

5. Software Sustainability Institute www.software.ac.uk What do we choose to identify: - Workflow? - Software that runs workflow? - Software referenced by workflow? - Software dependencies? What’s the minimum citable part? Boundary

Which authors have had what impact on each version of the software? Who had the largest contribution to the scientific results in a paper? Who had the largest contribution to the scientific results in a paper? Can micro-attribution work? Can track author, but not contribution? Can micro-attribution work? Can track author, but not contribution?http://beyond-impact.org/?p=175 OGSA-DAI projects statistics from Ohloh Why do we identify? - To measure - To restrict - To communicate - To include
