Transfer Metadata Workflow Operation

ID: transfer-metadata


The transfer metadata operation allows to transfer arbitrary metadata fields from one metadata catalog to another one.

Parameter Table

configuration key example description
source-flavor dublincore/episode The catalog from which the metadata is copied
target-flavor myterms/episode The catalog to which the data is copied
source-element {}creator The XML element to copy
target-element {}creator The XML element to which the values are copied
force false Overwrite existing targets
concat , Join multiple values by set delimiter
target-prefix dcterms Prefix to use for the given namespace


By default, the operation will fail if a target element already exists at the specified location. If force is set, all existing target elements will be removed before copying the new elements.


If multiple source elements are selected (e.g. the title in multiple languages), by default, all elements are copied to the destination. The language information are preserved in this operation. If concat is defined, the value of this option will be used as a delimiter for joining all selected source elements and only ever one element will be written. All language information for this combined element will be discarded in the process.


This option lets you specify the XML namespace identifier for the target elements namespace. For example, Opencast usually uses dcterms for elements from the set of DublinCore terms, resulting in elements like <dcterms:creator>.
