All but three of the allowed values in the DataCite controlled list terms for contributor type are defined by individual members of the class `pro:Role` in [PRO](http://purl.org/spar/pro), or of its sub-classes in [SCORO](http://purl.org/spar/scoro):

- `scoro:contact-person` (Contact Person)
- `scoro:data-creator` (Data Collector)
- `scoro:data-curator` (Data Curator)
- `scoro:data-manager` (Data Manager)
- `pro:distributor` (Distributor)
- `pro:editor` (Editor)
- `scoro:host-institution` (Hosting Institution)
- `pro:producer` (Producer)
- `scoro:project-leader` (Project Leader)
- `scoro:project-manager` (Project Manager)
- `scoro:project-member` (Project Member)
- `scoro:registrar` (Registration Agency)
- `scoro:registration-authority` (Registration Authority)
- `scoro:researcher` (Researcher)
- `scoro:rights-holder` (Rights Holder)
- `scoro:sponsor` (Sponsor)
- `scoro:supervisor` (Supervisor)
- `pro:translator` (Translator)
- `scoro:workpackage-leader` (Workpackage Leader)

The remaining two, i.e., “RelatedPerson” and “ResearchGroup”, can be specified as a type (by means of the property `rdf:type`) of the contributor under consideration by means of the following classes respectively:
- `foaf:Person` (Related Person)
- `frapo:ResearchGroup` (Research Group)

Note that many other individuals not required for DataCite metadata also exist within these [PRO](http://port.org/spar/pro) and [SCoRO](http://purl.org/spar/scoro) classes, e.g., `pro:copy-editor` and `scoro:principal-investigator`, and new individuals can easily be added to those ontologies, giving great flexibility.

Since roles have contexts and time constraints that are important to take into account (for example, a person can be author of one paper and reviewer of another, while another person will be editor of a journal only for a defined period, not for ever), the [PRO](http://port.org/spar/pro) and [SCoRO](http://purl.org/spar/scoro) ontologies permit these contexts to be specified, using the Time-indexed Value in Context ([TVC](http://www.essepuntato.it/2012/04/tvc/)) ontological design pattern.  

Thus, the domain of `pro:withRole` is not `foaf:Agent`, but rather a member of the class `pro:RoleInTime`, which itself is the range of the property `pro:holdsRoleInTime`, for which the domain is `foaf:Agent` (i.e., our contributor).
