Special status components
A set of six components enjoy a "special" status, in the sense that they can be attached to various components performing different roles, namely personInfo, organizationInfo, communicationInfo, projectInfo, sizeInfo and documentInfo. For instance, sizeInfo can be used either for the size of a whole resource or, in combination with another component, to describe the size of parts of the resource (e.g. per domain, per language etc.); personInfo is used for contact persons, resource creators, license signatories, annotators of a corpus etc.
