Avalon 2016 Overview

  1. 1. Avalon Media System Jon Dunn Indiana University Bloomington Evviva Weinraub Northwestern University Open Repositories, 2016 16, June 2016
  2. 2. Avalon, A History
  3. 3. What is Avalon? Open source software system that enables libraries and archives to provide access to audio and video collections • Hydra Solution Bundle • Goals: – Easily installable and configurable – Serve a variety of use cases and institutions – Create a basis for sustainable development
  4. 4. Why Avalon? • Existing repository systems don’t work well for time-based media – Issues: integration with streaming servers; hard to support time-based navigation; difficulties in integrating access control • Existing media systems don’t work well with repositories – Issues: focus on short-term access for teaching and learning; limited metadata and access control capabilities; integration with preservation workflows
  5. 5. Project Funding • 2010 – 2011: IMLS Planning Grant • 2011-2015: National Leadership Grant from the Institute of Museum and Library Services • 2015-2016: Andrew W. Mellon Foundation Partnership between libraries at Indiana University and Northwestern University
  6. 6. Goals of current Mellon grant 1. Develop additional Avalon functionality 2. Conduct studies of use of audio and video collections by humanities researchers 3. Develop and implement a community-funded business and governance model 4. Deploy Avalon in a hosted SaaS model for testing/pilot

  27. 27. Moving Forward
  28. 28. Lessons Learned from Advisory Board • Clearly define and focus on our core product • Ensure that Avalon is complementary to, not overlapping with, other solutions in the repository and media space • Keep the product as general purpose as possible to help drive adoption • For many institutions, modularity and ability to integrate with existing repository solutions is a key requirement • Partnerships should be chosen wisely • Reduce technical debt (e.g. keeping up with Fedora 4 and Hydra) is important for local installations • Integration with a variety of research and analysis tools will be important for scholarly uptake
  29. 29. Avalon 5.0 Launched June 13th • Organization and Sharing Features – Create private or shareable Playlists – Add whole audio and video files or clips to playlists • Content Ingest API – A lightweight API for importing metadata and links to existing derivatives into Avalon. • Access control enhancements – IP based access control – “Date digitized” field for master files. – Grant access permission for items for set periods of time • More granular searching – Searching now includes section and structure labels – “Date digitized” provided as admin facet . • Accessibility phase 2 – Support for ingesting/delivering captions in VTT and/or SRT files – Player shows captions when available – End user can toggle captioning on/off via player control - mouse and keyboard. Final Fedora 3 Release
  30. 30. Avalon 6.0 (Expected October 2016) • Feature parity with R5 but on Fedora 4 • Additional transcode engine support (besides Matterhorn) • Upgrade to Hydra 9 / Fedora 4 • Support HLS Flash and retire RTMP support • LDAP based groups for assigning collection staff roles • Other possible features • Better visibility of access control status for bulk selected items
  31. 31. Future Development Strategies • Avalon as a SaaS – Cloud deployment model – Working to develop partnership with Infrastructure Based Service companies – Interested in sites willing to pilot • “Gemification“ of Avalon Architecure (Expected release Winter 2017) – Re-factoring Avalon code for paying off technical debt – Modularizing core Avalon components – Making Avalon components easier to install for other institutions – Re-architecting for full service and gems for other open source repository solutions – Building up from CurationConcerns • Creating a Robust Open Development Community – Using other open source projects as a guide – Potential introduction of Avalon Developers Conference to train and introduce code base to wider developer audience – Introduction of community based sprints
