The metadata formats that are available for packaging are all standards based XML documents. Specifically they are either DDI Codebook or Lifecycle, or Triple-S XML.

DDI Codebook

The following is true for all the DDI codebook formats (DDI_C122, DDI_C21, DDI_CNES, DDI_C25)

DDI_C122 - DDI Codebook 1.2.2
DDI_C21 - DDI Codebook 2.1
DDI_C25 - DDI Codebook 2.5
DDI_CNES - Nesstar compliant DDI Codebook
