filter

A logical value. If TRUE, then DataONE packaging relationships are omitted.

identifiers

A list of character values of the identifiers of DataPackage members.

Details

The filter argument causes DataONE packaging relationships to be removed. A description of these can be viewed at https://purl.dataone.org/architecture/design/DataPackage.html. The identifiers parameter can contain a list of DataPackage members for which the identifiers will be 'demoted', that is any relationship that has these identifiers as a URL as the subject or object will be changed to the 'bare' identifier. The intent of these two parameter is to transform the DataPackage to a 'local' state, so that it can be more easily updated locally.
