Synchronizing DOI metadata
When we publish a project on PhysioNet, we also create a DOI and publish various metadata using the DataCite API.
From time to time we may want to make improvements to this metadata, such as by adding new fields (e.g. pull #2154, #2119).
It is also possible - though discouraged! - for site administrators to modify projects after publication, such as to fix a typo in a project title or an author's name.
In both cases, we want to update the information for existing projects. It doesn't have to be done immediately but it should be done reasonably quickly, and automatically.
We could try to track whether a particular DOI needs updating, but this could be complicated and error-prone. It feels like it would be better just to update all published DOIs regularly (say, once a week), as long as it's not a burden on the API.
