The Wellcome has recently announced an updated policy on sharing research outputs. This policy develops their existing policies on Open Access publishing and research data to emphasise the importance of sharing research software and other research outputs. This forms part of the Wellcome’s broader promotion of Open Research practices.
You can find the announcement of the Wellcome’s new policy on their website. If you need support with writing an ‘Outputs Management Plan’ for the Wellcome or another funders further guidance is available.
