DataCite is expanding its Metadata Schema

The DataCite Metadata Schema is a list of core metadata properties chosen for an accurate and consistent identification of a resource for citation and retrieval purposes, along with recommended use instructions. The DataCite Metadata Working Group released a new version (4.4) of the DataCite Metadata Schema Documentation for the Publication and Citation of Research Data and Other Research Outputs. This release of the Metadata Schema contains better support for textual publications. Important changes are the addition of specific resource types such as journal, journal article, dissertation, etc., and also includes computational notebook and peer review, so that these types can be better identified. Also, a new property, relatedItem, is introduced which contains information about a resource related to the one being registered, e.g., a journal article, conference paper, or a book series. It can be used to describe a text citation where relatedIdentifier cannot be used because the related resource does not have an identifier.
