Indiana University Bloomington Libraries is involved in two new projects to digitize and store content and related metadata. Each of these projects presents unique challenges. We want to use the same technology stack for both, however, so we are choosing Fedora as a storage mechanism, with Hydra-based Sufia as a repository front end. We will discuss our decision, show advantages of this Hydra/Fedora framework, and discuss advantages of moving to Fedora 4. We will also contrast this framework with the way we might have approached these projects in the past with previous versions of Fedora and before Sufia or Hydra were options. and A presentation given at the Open Repositories conference in 2015 held in Indianapolis described thus

Indiana University and Northwestern University, in collaboration with nine partner institutions, recently completed the last year of a three-year IMLS-funded effort to build the Avalon Media System, an open source solution for managing and providing access to digital audio and video collections, based on Fedora and the Hydra repository software development framework. As the Avalon platform reaches maturity, several institutions are in the process of implementing Avalon both to replace current time-based media access solutions and to support new use cases. In addition, new funding from the Andrew W. Mellon Foundation will support continued work to develop new features, grow and provide support for the community of adopters, and move Avalon towards organizational and financial sustainability. This panel will bring together project leaders from Indiana and Northwestern, along with Avalon community members at the University of Virginia and Stanford University, to share experiences of implementing Avalon at their institutions, integrating Avalon with other local systems, and supporting Avalon to enable a variety of use cases in research, teaching, and learning. Panel members will also discuss future development plans and provide a preview of how the project intends to transition from a grant-supported endeavor to a community-sustained solution. and Slides for a panel presentation given at the Open Repositories conference in 2015 held in Indianapolis described thus

A lightning talk at Samvera Virtual Connect 2019 described thus and What if the Hyrax web application were to support and include, by default, controlled vocabularies from marginalized communities? Currently Hyrax supplies a default set of descriptive metadata fields for describing uploaded objects. This set of fields includes Keyword (a required field) and Subject (an optional field). Neither of these fields are controlled by a vocabulary of terms upon install. The Questioning Authority (QA) gem exists as an option to configure and apply controlled vocabularies for use with fields such as these in Hyrax. While QA can be configured to work with nearly any vocabulary, the current vocabularies offered through the gem when it is installed include LCSH/NAF/GFT/MPT/DGT, FAST, Geonames, MeSH, Agrovoc, DBPedia, NALT, and Getty (AAT, TGN, ULAN). These are widely used mainstream sources for topical subject and genre description but also tend to reflect the current dominant mainstream power structure in the United States (white, male, straight, able-bodied, middle-class, Christian, Anglo). Should we increase the list of vocabularies available, by default, in the QA gem? Should we go beyond that and enable vocabulary choices on the default Subject and Keyword Hyrax fields? This lightning talk will discuss these questions and consider vocabulary options that would provide more inclusive descriptive capabilities.

A lightning talk at Samvera Virtual Connect 2019 described thus and The Timeliner is a pedagogical tool that was available in the old Variations application, the Avalon predecessor. It allows for a visual representation of the structure of an audio file or fragment. The tool, which will be made available as a standalone, has been reimplemented using IIIF Presentation API v3 for the presentation layer and the IIIF Auth protocol for the integration with Avalon. We will show the tool and also discuss the technical aspects of the IIIF standards.

A lightning talk at Samvera Virtual Connect 2019 described thus and Avalon Media System is upgrading it's UI component for handling structural metadata editing for an audio or visual work. The user can select and organize timespans in an AV work by manually typing bounding times and titles, or by interacting with a visual representation of the waveform. Technologies used are Peak.js and ReactJS.

A lightning talk at Samvera Virtual Connect 2018 described thus and Avalon Media System is working towards a release to integrate with Hyrax in support of time-based media formats. This includes creating a Work type to support the needs of audio and video formats and provide an upgrade path for those who have been using Avalon in it’s previous releases as a standalone Samvera product. Join us for a look at the new Audiovisual Work type, specifically how we’re transitioning descriptive metadata from MODS XML to RDF.
