I think that citations to open access research within patents would be interesting to capture. Could use lens.org.

I want an journal metric that shows the take the DORA serious, and do not actually use the false JIF metric.

Add open data policies Add policies about material and method section

Cost of OA publishing per journal/publisher.

I think APCs should be included and monitored. At the same time, also pre-print and post-print policies need to be considered. A quantitative indicator to be included can be the embargo period.

Number of journals that allow preprints, and postprints, and what their embargo periods are. Suggest also looking at the OAS evaluation tool: https://www.tandfonline.com/do... The fact that the Avoin Tiede report for measuring the openness of journals and publishers has not been included here, nor any of the evaluation criteria within, is deeply concerning. https://www.tandfonline.com/do...

Other things: Journals that accept articles based on soundness only; journals that use registered reports; journals that encourage reproducibility studies; journals that encourage publication of 'negative results'. These are all key aspects of open science that are missing.

Furthermore, journals that still advertise impact factors in some form should be included in this.

Publishers' policy. You might include here also book publishers.

You might consider also adding publishers' policies, in order to also include book publishers.
