The metadata edited in the Metadata Editor is not stored within the respective data object (TEI object) but in an external metadata database. The header metadata of the TEI object may or may not be identical with the external metadata. In some cases – e.g. if a new object is created – it might be desirable to copy the external metadata into the object header. This can be done by clicking on the Generate TEI Header button at the bottom of the Metadata Editor view.
