Most Geodata harvest portals and Catalogs recommend to use a UUID for the ISO19115 MD_Metadata.fileIdentifier field.
My proposal: add an additional column Entry.uuid and keep Entry.id as a unique identifier in metacatalog, as MD_Metadata.fileIdentifier is a free text field, which would slow metacatalog significantly down. I prefer to run queries against an Integer primary key.
