The version control of the data is conducted through metadata using the DataCite schema, which makes use of related identifiers to link versions that are derived from the AIP, or which provide major or minor versions of the original AIP. Changes in datasets will trigger a major version whereas additional details about the dataset will trigger a minor version. | The version control of the data is conducted through metadata using the DataCite schema, which makes use of related identifiers to link versions that are derived from the AIP, or which provide major or minor versions of the original AIP.
