use the more portable encoded_item format for exported items - but with added attributes so we can use it as a reasonably complete item backup. The encoded_item format gives us extended author and owner information in case we need to probe them to bring the entry back. It also contains taxonomy entries. Importing and/or recovering will best be accomplished in chunks. It could take some time and some memory to chew through this.
