@sacha.hodencq Data license recommendations form part of a long running discussion within our community. And my voice is only one among many. But I believe that license interoperability is key and has not always been given sufficient attention. In the yet‑to‑be‑submitted Data Act feedback, I recently wrote the following paragraph:
The debate on choice of license rarely looks at the question of legal interoperability. Rather, the merits of individual classes of license are debated and then the merits of individual licenses. This same discussion takes place within our community too. But this approach tackles the problem from the wrong end. Instead, license interoperability must be a paramount consideration.
Therefore this comparability graph should be centre stage:
Worth noting too that the European Commission is increasingly using CC‑BY‑4.0 licensing. And that it is also the default on Zenodo.
When a consensus does form, we should go through the various openmod documentation and make it consistent. Until then, I myself will not edit and overwrite the views of others on this important question. HTH R
