Analysis

• This will require improvements to METS reader-writer (metsrw) to be able to support different queries
• METS can contain multiple metadata standards - metsrw should be able to handle these in an easily-extensible way
  • Since it is the METS reader-writer, other standards should be supported as plugins of some sort
  • Prefer to use existing libraries (eg PyPREMIS) or thin wrappers around existing libraries
• By default metsrw should include PREMIS in the way Archivematica uses it and DublinCore
