I want to know the answer to the following question:
What does the OA policy cover ?
All the background I'm provided with is that "In November 2014, the Bill and Melinda Gates Foundation announced that they are adopting an open access (OA) policy for publications and data, "to enable the unrestricted access and reuse of all peer-reviewed published research funded by the foundation, including any underlying data sets".". Is that enough to answer the question?
Answer: no
