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.
A free, open source media preservation prioritization web application created in a collaboration between AVPreserve and Indiana University. MediaSCORE (Media Selection: Condition, Obsolescence, and Risk Evaluation) enables a detailed analysis of degradation and obsolescence risk factors for most analog and physical digital audio and video formats. MediaRIVERS (Media Research and Instructional Value Evaluation and Ranking System) guides a structured assessment of research and instructional value for media holdings.
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 generatio
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 eff
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 refineme
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 upl
AVCC is a set of forms and guidelines developed to enable efficient item-level cataloging of audiovisual collections. Each module (Audio, Video, Film) includes individualized data entry forms and reports that quantify information such as format types, base types, target format sizes, and other data
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
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.
