Software Sustainability Institute Authorship Lifecycle Identif y Cite Reuse Research Index Papers, data, software all research outputs of a continuous cycle. With software, technology makes it easier to track, but not reward. We cannot separate papers, data and software when we release research.

Software Sustainability Institute The current process Start research Write software Use software Produce results Produce results Publish research paper Release data Release data Release software Release software Which mentions software and data This process is simple but does not reward production or reuse of good software and data. It also has a long contribution cycle.

Software Sustainability Institute Write software A better process? Start research Identify existing software Identify existing software Use software Produce results Produce results Publish research paper Adapt/ extend software Release data Release data Release software Release software Publish software paper Publish software paper Publish data paper Publish data paper Which references software and data papers Software and data papers are needed as proxies for rewarding reuse. But it enables a shorter contribution cycle for data and software.

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

Software Sustainability Institute Authorship Authorship Which authors have had what impact on each version of the software? 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? OGSA-DAI projects statistics from Ohloh

Software Sustainability Institute Moving forwards Making software citable  At “package level” (is this the right granularity?) GitHub -> Zenodo / FigShare / Insititution Repo    Principles for citation Force11 Software Citation Working Group   Making roles clearer Project Credit  Contributor Badges   Code as a Research Object Defining minimal metadata  How do we ensure this is “linked up” with RepoFringe community?
