O Factor: Open-Open citation measure

Measures such as Impact factor and H-Index are used to reflect the impact of scientific publishing and authors' productivity. There have been many arguments in support of and against these measures: whether they truly taking all factors into consideration and whether they must be used as the bottom-line in deciding worth of published content and authors who contribute content. However, measures such as Impact factor and H-Index and other indices continue to used, rather overwhelmingly, as measures of quality and productivity. The other facet the quality paradigm is the question of quality of Open content. Open access advocates endeavour to entice academicians and researchers to publish in open journals and other open resources. Academicians are hesitant to publish in open access journals because open access publishing has still not attained the status that commercial published journals have. Here we address the question 'How to establish quality of Open Content?' We introduce the concept of 'Open Content Metrics (OCM)' as counterparts of the measures of quality and productivity already established for commercially published journals. We introduce the concept of O-Factor (OF) as a measure to reflect what we refer as Open-Open citation. Data and illustration to calculate OF are provided.
