Object relationship types
Relationships between data objects is a part of the DataCite scheme and is also included in the MDR. The types available are listed below and are self-explanatory. In almost all cases they come as corresponding pairs, allowing both ‘views’ or perspectives on a relationship between data objects to be stored. The expectation would be that both representations of a relationship would be stored in the database.
For clinical trial data objects the ‘Has Metadata’ / ‘Is Metadata For’ is often particularly important, allowing both the data and the descriptive metadata, which is also a data object in tis own right, to be described and linked for a particular dataset.
In the descriptions in the list that follows (drawn from DataCite), A is the ‘source’ data object, and B is the related data object.
