Decide on primary package identifier
Morpho 1.x uses the EML datapackage ID for displaying search result records, opening, saving, etc.
With Morpho 2.x incorporating the DataONE DataPackage (ORE) model, we have the opportunity to switch to the ORE object identifier as the primary mechanism for identifying the overall package. This would be more consistent with the model, but requires that EVERY EML file have an ORE that packages it.
It's also unclear how you could open an older EML document unless we supported both. Maybe we can allow opening older EML packages, but only allow you to save ORE packages?
