There are many contributors to the OA advantage, but currently, with spontaneous OA self-archiving still hovering at only about 15%, a competitive advantage is one of its important components (Figure 5). (The University of Southampton, the first to adopt a self-archiving mandate, already enjoys an unexpectedly large "G-Factor," which may well be due to the competitive advantage it gained from being the world's first to mandate OA self-archiving: Figure 6) With the growing use of research impact metrics, validated by the UK RAE, the OA advantage will become much more visible and salient to researchers. Together with the growth of data impact metrics, alongside publication impact metrics and the prominent example of how scientometrics can data-mine its online database, there should now be a positive feedback loop, encouraging data self-archiving, publication self-archiving, OA self-archiving mandates, and the continuing development of the functionality of the underlying infrastructure.
