Description: Currently gbif-doi is based on DataCite Metadata Schema 3.1.

DataCite has just released version 4.0 of its Metadata Schema. Changes in this version include:
* Changing resourceTypeGeneral from optional to mandatory
* *Addition of a new property: FundingReference, with subproperties funderName, funderIdentifier, awardNumber, awardURI and awardTitle. Deprecation of contributorType “funder”*
* Addition of new optional subproperties for creatorName and contributorName: familyName and givenName
* Addition of a new relatedIdentifierType option “IGSN”
* Addition of a new subproperty for GeoLocation “geoLocationPolygon”, and changing the definition of the existing GeoLocation subproperties (geoLocationPoint and geoLocationBox)

[According to DataCite|https://blog.datacite.org/metadata-schema-4-webinar/], "These changes are important in improving data discoverability and reusability, and helps to grant proper credit to data creators."

Fortunately gbif-doi's classes and builders are automatically generated from the DataCite XSD using "maven-jaxb2-plugin". Instructions on how to manually execute the plugin can be found in the POM of gbif-doi.

After upgrading gbif-doi to use the new version of the metadata schema, the Registry and IPT projects can take advantage of its recent set of changes/improvements.
