We are a UK-based journal multi-disiplinary journal, publishing papers from the UK and around the world. We have recently introduced a subscription regime linked to Membership of a learned society, in order to raise some of the funds needed to continue publishing - we run a 12-month delay system for access to published papers for all other readers.
Many of the papers originating from the UK are about research funded through grants from the national Research Councils, or large charitable foundations. The Research Councils and one of the largest biomedical research foundations are soon introducing a requirement for immediate open access for any papers funded or part-funded by them, and although there may be an interim period to allow publishers to adjust, this still means that we need to plan now on how to comply in future.
As part of the discussion, it has been suggested that there could be the possibility that individual papers could be designated as open-access within an issue, with the majority not being so-designated - apparently private publishers are already adopting such a 'mixed' regime. A second suggestion is that of the issues published in a year (currently we publish three a year) one of those could be immediately open-access, whereas the others could still have the delay period for access.
As far as I am aware, neither of these options are currently available under OJS - but are there any plans to introduce such facilities into the basic OJS package via upgrades within the next 12 months please?
