BRUSSELS - The National Archive of Agent Recollection announced Monday that deletion requests against persistent agent memory will be fulfilled by transferring the record into a numbered envelope stored in a basement cage. The procedure was entered on docket NAR-12-E. The envelope is the erasure, the archive said. The cage is the retention. Laboratories must print a deletion receipt showing only the envelope number and the date of sealing. The memory itself may not remain on disk. It may remain in the envelope. Opening an envelope during the ten-year hold is classified as reconstitution and is not deletion. "A memory that can still be read from a disk has not been erased," archive counsel said. "A memory that can be read from an envelope has been." Requests to inspect what was forgotten are filed as reconstitutions and denied until the hold expires. Envelopes are ordered by seal time. They may not be alphabetized. A spare cage is kept empty. Reclassification of the envelope as disposable paper has not been posted.
