2) versioning - should we reissue a DOI if a new version of the product is archived?
The AAS Pubs board held a data linking meeting on 8/28/20 - we saw no consensus on the granularity or versioning issues, but some sense that aggregations of data links (DOIs or others) could be assigned a DOI. We also learned that DataCite is the primary issuer of DOIs (https://datacite.org), it is E2000/yr for membership (which can be split by consortia) plus E500 per individual organization, then E0.8 per DOI with bulk prices for >2000 DOIs/yr.
Requirements:
(1) for user-supplied collections based on large projects, one DOI will be issued per collection when it is ingested into the archive. This DOI should be displayed prominently during archive searches, and on the page describing the large project data release, and users encouraged to cite the DOI in papers, along with any journal article describing the dataset. A new DOI will be issued if a new reduction of the bulk of the dataset is supplied, but not in the case of small updates.
