Throughout 2020, a project is run to prepare for the OA Switchboard (a collaboratively developed and community run open source solution) to go live as an operational solution. The OA Switchboard provides essential infrastructure and back office services to facilitate the fulfilment of open access strategies across business models, policies and agreements via: 1. communication standards (‘metadata’); 2. technical solutions (‘hub’); 3. standardised real-time monitoring and reporting. The essence of the problems it aims to address as a priority: - It is complicated/cumbersome to find out how to get the service charges for a certain OA publication settled, and to prepare for (enable) such financial settlement - It is a challenge to monitor funds and track spending in real time In the current situation, enabling open access to scholarship has never been more pressing. Supporting the OA Switchboard is investing in open source infrastructure that will ensure that transformational change to open access can be achieved by all publishers, whilst reducing complexity for funders, institutions and researchers. It will also work alongside and strengthen other initiatives that the Wellcome Trust is supporting in this space, specifically in realising the synergies of interlinking the Journal Checker Tool and the OA Switchboard.
