What inspired the request?
#10288

What existing behavior do you want changed?

• add a new subfield topicClassTermURI (with topicClassification as the parent) to the citation metadata block
• migrate contents from topicClassVocabURI or topicClassValue to topicClassTermURI (if that field was used for a term URI before)
• change DataCite export format, so that the content of topicClassTermURI goes into the property valueURI of the subject element: topicClassValue
