What is a “DISOWN” record?
A mark/release record with a DISOWN File ID signifies that the PIT tag code was originally reported to PTAGIS in a Tag Data file, but that the tag code was removed from a subsequent version of that Tag Data file. A change has been made to FDVL, the Field Data Validation and Loading process, to help users detect inadvertent omissions after submitting updated tagging files to PTAGIS. Before the change, when processing a tagging correction, FDVL would delete from the tag_data table any detail record that had been removed from the associated tagging file since its previous submittal. After the change, FDVL will mark each such record with a fictitious file_id of DISOWN, rather than deleting it. Users may be familiar with another fictitious file_id, ORPHAN, signifying a PIT tag for which one or more interrogation records have been received, but no tagging file has been processed.
