Purpose

This function generates the identifier XML of the repository. The function can be called with a parameter (node identifier) or without.

In the case of no identifier, the module lists all the metadataformats available; lom_ieee, lom_ims and oai_dc (name reserved by OAI).

If an identifier is provided, the module lists only the metadata formats available for the specific record (the oai_dc is always provided, the the two depend on the record).

Error conditions

• badArgument -> The request includes illegal arguments or is missing required arguments.
• idDoesNotExist -> The value of the identifier argument is unknown or illegal in this repository.
• noMetadataFormats -> There are no metadata formats available for the specified item.
