I am wondering where can I find definitions or more detailed descriptions for the “program” node? Is there a full documentation page like this one for crossref4.4.2?
On a different note, the link to the example deposit file on this page seems obsolete as it points to the 0.0.1 version on GitLab.
There are other program elements relating to licensing, funders and clinical trials but I hope this information was what you were looking for. If not then please do let me know the parts you are looking for and I will try to get those details over to you as well.
