Crosswalk metadata from external XML representation to DSpace internal representations. This version accepts metadata as a
List of JDOM XML elements. It interprets the contents of each element and adds the appropriate values to the DSpace Object's internal metadata represenation.
Note that this method may be called several times for the same target Item, if the metadata comes as several lists of elements, so it should not add fixed metadata values on each or they may appear multiples times.
NOTE:
Most XML metadata standards (e.g. MODS) are defined as a "root" element which contains a sequence of "fields" that have the descriptive information. Some metadata containers have a "disembodied" list of fields, rather than the root element, so this ingest method is intended to accept that bare list of fields. However, it must also accept a list containing only the "root" element for the metadata structure (e.g. the "mods:mods" wrapper in a MODS expression) as a member of the list. It can handle this case by calling the single-element version of ingest() on the "root" element.
Some callers of the crosswalk plugin may not be careful about (or capable of) choosing whether the list or element version should be called.
