Infrastructure for data on open access: openness, sustainability, reproducibility

There are still considerable limitations for conducting comprehensive open access. monitoring. Over the last decade science policy has been pushing hard for open access, but open data and tools for monitoring the current status and in particular development over time are still lacking. Current bibliometric databases used for publication analysis in the context of openness have their biases and limitations in how comprehensively journals across disciplines, countries, and languages are selected for inclusion. Being commercial, access to them is limited, and datasets created on the basis of such data can rarely be freely redistributed in their most usable form. In order to understand how the landscape is changing over time it would be important to be able to capture the publisher, journal, and article-level developments in a consistent and reliable way. Key questions that will be discussed: What pieces of the infrastructure are still missing? What questions still go unanswered because of this? Why and how should the information environment for open access be improved?
