DOI Versioning Done Right

Spring 2017 Zenodo launched a new DOI versioning scheme. Unlike DOI versioning schemes in other generic repositories, no semantic versioning information is included in the identifier string. Instead, DOIs for versions of the same resource are semantically linked in the DataCite metadata registered along with the DOI. Furthermore, an additional DOI representing all versions is also registered to provide an aggregated view for discovery systems. The poster presents use cases, user interface design considerations and implementation details of the new DOI versioning scheme on Zenodo.
