Exactly is a simple and easy to use application for remotely and safely transferring any born-digital material from a sender to a recipient. Exactly utilizes the BagIt File Packaging Format (an Internet Engineering Task-Force standard, developed by the Library of Congress and the California Digital Library, with current support from George Washington University and the University of Maryland), supports SFTP/FTP transfer, as well as standard network transfers, and integrates into desktop-based file sharing workflows such as Dropbox or Google Drive. Additionally, Exactly allows the recipient to create customized metadata templates for the sender to fill out before submission. Exactly can send email notifications with transfer data and manifests when files have been delivered to the archive.
Building on work originally begun by the Gates Archive, AVPreserve and the Louie B. Nunn Center for Oral History at the University of Kentucky Libraries developed Exactly to meet the growing need for archives to acquire born digital content directly from donors and to begin the activities of establishing provenance and fixity early in the process of acquisition. Read more about how the Nunn Center is using Exactly here.
AVPreserve hosted a few webinar on Exactly in January 2017. The recording of the webinar can be viewed here.

Fixity is a utility for the documentation and regular review of stored files. Fixity scans a folder or directory, creating a manifest of the files including their file paths and their checksums, against which a regular comparative analysis can be run. Fixity monitors file integrity through generation and validation of checksums, and file attendance through monitoring and reporting on new, missing, moved and renamed files. Fixity emails a report to the user documenting flagged items along with the reason for a flag, such as that a file has been moved to a new location in the directory, has been edited, or has failed a checksum comparison for other reasons. Supplementing tools like BagIt that review files at points of exchange, when run regularly Fixity becomes a powerful tool for monitoring digital files in repositories, servers, and other long-term storage locations.

AVCC is an open source web application developed to enable collaborative, efficient item-level cataloging of audiovisual collections. The application incorporates built-in reporting on collection statistics, digital storage calculations, shipping manifests, and other data critical to prioritizing and planning preservation work with audiovisual materials.
AVCC establishes a minimal set of required and recommended fields that provide basic intellectual control that enables quantification, planning and management of collections. The focus of of AVCC is two-fold: to uncover hidden collections via record creation and to support preservation reformatting in order to enable access to the content itself.
Catalyst is an innovative method of creating item-level inventories of audiovisual collections. The process uses a team of photographers onsite to image each item in a collection, capturing all information-carrying sides of a cassette/reel/disk, its housing, and any paper inserts. The photos are uploaded daily to our central server where they are sorted into item records and fields for Unique ID, Location, and Format are automatically generated. After this the database records are immediately accessible by a team of offsite catalogers who use the images to enter further metadata. Taking advantage of automated processing and minimal datasets, even a small team can work through hundreds or thousands of items a day. Catalyst data can be exported to generate reports for preservation planning and selection, or to become the basis of a finding aid or more complete catalog record. The benefit of the photos is that materials can be searched for and reviewed without the need to pull tapes until correct items are identified, minimizing handling and staff time. Also further descriptive cataloging can take place at a more reasonable pace or after reformatting has been completed. The Catalyst Inventory software is currently only available as part our inventory services, but screenshots are posted below or here and here.

The Archival Management System (AMS) is a multi-functional tool that supports management of the digitization workflow, especially useful for projects involving multiple departments or organizations. Existing functions in this open source software include: 1) Aggregation and normalization or refinement of collection inventories. Using tools such as Open Refine and MINT, data cleanup can be done analytically and in bulk, though the system also allows individual record-level editing. 2) Prioritization and selection of items for digitization. 3) Scheduling and system alerts to inform users when it is time to begin packing materials for shipping to digitization vendors, shipping dates, when the vendor has completed a batch, and when the materials will be shipped back. 4) Record level search which includes an audio or video player for playback of the digitized item. 5) Bulk ingest of technical and preservation metadata generated by the vendor. 6) Dashboard reporting that tracks project progress, including number and types of items, percentage of project completed, departments/locations, and other pertinent information. AMS was originally developed to support the digitization of 40,000 hours of audiovisual materials from 120 public media stations as part of the Corporation for Public Broadcasting American Archive project, and AVPreserve has also customized an instance for the Flemish Institute for Archiving (VIAA) to manage nationwide digitization from broadcasters, universities, and museums. The source code is available for download from GitHub, and AVPreserve can also provide services to customize it for project particulars such as organizational structure, workflow specifics, language, other material types (such as newspapers), reporting, systems integration, and more. A sandbox instance will be available here soon.

MDQC reads the embedded metadata of a file or directory and compares it against a set of rules defined by the user, verifying that the technical and administrative specs of the files are correct. This automates and minimizes the time needed to QC large batches of digitized assets, increasing the efficiency of managing digitization projects. MDQC can be used on any file type supported by ExifTool and MediaInfo. Both ExifTool and MediaInfo will need to be installed on your system in order for MDQC to work.

BWF MetaEdit is a free, open source tool that supports embedding, validating, and exporting of metadata in Broadcast WAVE Format (BWF) files. BWF MetaEdit is available for download at SourceForge and was developed by the Federal Agencies Digitization Guidelines Initiative to support its guideline for embedded metadata in the bext and INFO chunks. The application was developed by AudioVisual Preservation Solutions.
Users of BWF MetaEdit can:
- *Import, edit, embed, and export specified metadata elements in WAVE audio files
- *Export technical metadata from Format Chunks and minimal metadata from bext and INFO chunks as comma-separated values and/or XML, across a set of files or from individual files
- *Evaluate, verify and embed MD5 checksums, as applied to the WAVE file’s data chunk (audio bitstream only)
- *Enforce the guideline (above) developed by the Federal Agencies Audio-Visual Working Group, as well as specifications from the European Broadcasting Union (EBU), Microsoft, and IBM
- *Generate reports that show errors in the construction of WAVE files
- *Choose from command line and GUI, for Windows/PC, Macintosh OS, Linux.
AVI MetaEdit supports embedding and validating metadata in RIFF-based AudioVisual Interleave format (AVI) video files. AVI is currently the target format for creation of Preservation Masters within the Digitization Services Branch at the National Archives.
reVTMD is an XML schema tailored to include fields that address the creation and long term management of reformatted videos, especially with the cultural heritage community. It is a concise subset of the large array of technical metadata available, structured in a way to make it highly usable for accessing and managing all types of video files beyond AVI.
Both tools were developed by NARA in collaboration with AudioVisual Preservation Solutions. AVI MetaEdit is available for download at NARA’s GitHub site, and reVTMD is available on NARA’s website.
interstitial is a tool designed to detect dropped samples in audio digitization processes. These dropped samples are caused by fleeting interruptions in the hardware/software pipeline on a digital audio workstation. The interstitial tool Follows up on our work with the Federal Agencies Digitization Guidelines Initiative (FADGI) to define and study the issue of Audio Interstitial Errors.
interstitial compares two streams of digitized audio captured to a digital audio workstation and a secondary reference device. Irregularities that appear in the workstation stream and not in the other point to issues like Interstitial Errors that relate to samples lost when writing to disc. This utility will greatly decrease post-digitization quality control time and help further research on this problem.

A simple Excel spreadsheet that shows the total capacity for 1/4 inch open reel audio, using variable for Track Configuration, Sound Field Configuration, Tape Thickness, and Reel Size. Assumes full tape reels and full use of capacity. Look for an online app version coming soon.
This report presents the findings of an ARSC Technical Committee study, coordinated and authored by AVPS, which evaluates support for embedded metadata within and across a variety of audio recording software applications. This work addresses two primary questions: (1) How well does embedded metadata persist, and is its integrity maintained, as it is handled by various applications, and (2) How well is embedded metadata handled during the process of creating a derivative? The report concludes that persistence and integrity issues are prevalent across the audio software applications studied. In addition to the report, test methods and reference files are provided for download, enabling the reader to perform metadata integrity testing.
DV Analyzer is a technical quality control and reporting tool that examines DV streams in order to report errors in the tape-to-file transfer process. DV Analyzer also reports on technical metadata and patterns within DV streams such as changes in DV time code, changes in recording date and time markers, first and last frame markers within individual recordings, and more. To those concerned with preservation and archiving, this means that you now have the ability to automatically monitor integrity during reformatting of DV tapes and extract meaningful metadata from DV files.
