Here’s a story to send shivers down archival spines: when transferring video files off LTO for the American Archive project, WGBH got an initial failure rate of 57%. After repeat tries, the rates improved; still, an unnervingly large percentage of files were never able to be transferred successfully. Even more unnerving, going public with our horror story got a big response from other archives using LTO -- it seems like many institutions are having similarly scary results. What are the real risks with LTO tape? Are there steps that archives should be taking to better circumvent those risks? This presentation will share information about LTO storage failures across archives world and discuss the process of investigating the problem at WGBH by testing different methods of data retrieval from LTO (direct and networked downloads, individual file retrieval and bulk data dump, use of LTO 4 and LTO 6 decks) and using checksum comparisons and file analysis and characterization tools such as ffprobe, mediainfo and exiftool to analyze failed files. We'll also present whatever results we’ve managed to turn up by the time of Code4Lib!

In 2001, public media representatives developed the PBCore XML schema to establish a common language for managing metadata about their analog and digital audio and video. Since then, PBCore has been adopted by a number of organizations and archivists in the moving image archival community. The schema has also undergone a few revisions, but on more than one occasion it was left orphaned and with little to no support.
Times have changed. You may have heard the news that PBCore is back in action as part of the American Archive of Public Broadcasting initiative and via the Association of Moving Image Archivists (AMIA) PBCore Advisory Subcommittee. A group of archivists, public media stakeholders, and engaged users have come together to provide necessary support for the standard and to see to its further development.
At this session, I'll discuss the scope and uses of PBCore in digital preservation and access, report on the progress and goals of the PBCore Advisory Subcommittee, and share how the group (by the time of the conference) will have transformed the XML schema into an RDF ontology, bringing PBCore into the second decade of the 21st century. #PBHardcore
