The DataCite Metadata Working Group has been working on the next batch of Metadata Schema changes—and we need your feedback! Today, we are sharing a new Request for Comments (RFC) with several proposed changes to the DataCite Metadata Schema. Since Schema 4.5 was finalized, we have been working on numerous ideas put forward by the DataCite community—some of which are reflected in this RFC. The set of changes we are sharing here is not yet a complete schema version; rather, this RFC contains an assortment of changes that may be released in different versions—for example, some changes may be released in Version 4.6, while others may be scheduled for later versions. The implementation details and release timing of specific changes will depend on complexity, backward compatibility, and the DataCite development roadmap.
