1 The Avalon Media System Yale University November 24, 2014 Jon Dunn Indiana University Mark Notess Indiana University Julie Rudder Northwestern University

2 Agenda Introduction & Overview – Jon Dunn, Indiana Demo – Julie Rudder, Northwestern Technical architecture, development process, release plans – Mark Notess, Indiana NU implementation and services - Julie IU implementations and services – Mark Future directions – Jon Q & A - All

3 Avalon Project Objectives Goal: Create an open source system to enable libraries and archives to provide online access to video and audio collections Digital audio/video management and delivery system, focused on needs of libraries and archives Follow an agile, open source development model Leverage existing technologies, where feasible Communicate and market the project broadly to increase awareness and grow the community of users and developers

4 Project Overview Funded in part by a National Leadership Grant from the Institute of Museum and Library Services Original name: Variations on Video Planning grant: – August 2010 – July 2011 Implementation grant: – October 2011 – September 2014 September 2015 Partnership between libraries at Indiana University and Northwestern University

7 Avalon is a Hydra Solution Bundle

8 Why Avalon? Existing repository systems don’t work well for time- based media – DSpace, Fedora, Digital Commons, ContentDM, … – 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 – Kaltura, Brightcove, Ensemble, ShareStream, … – Issues: focus on short-term access for teaching and learning; limited metadata and access control capabilities; integration with preservation workflows Strong desire for community-based solution

Other pieces are leveraged. Users Fedora Solr Matterhorn Media Server Media Player (mediaelement.js) Can- Can Ruby- horn Hydra Head Black- light Omni- Auth

11 Release History 0.1 – July – October – May – October – May – July – December 2014 (expected)

12 Brian Keese developer Leah Lee developer Chris Colvard lead developer Julie Hardesty metadata specialist Cynthia Ramlo lead user experience designer Jon Dunn project director Mark Notess product owner Ariadne Rehbein project assistant Dan Zellner testing and production support Michael Klein lead developer Stefan Elnabli audiovisual specialist Karen Miller metadata specialist Julie Rudder product owner Claire Stewart co-project director Development Team

13 Current development process A single, blended team Agile Scrum process Code in public GitHub Face-to-face meetings at least 2x/year Daily standups, IRC

14 0 – 3.1 Release functionality End-user functionality Faceted discovery for search and browse Video and audio playback in browsers or on mobile devices Stream-level security Ability to embed media player in other websites Persistent URLs RTMP and HTTP streaming, Flash and HTML5-based player Collection management Interactive or batch uploading of media files and MODS metadata Private collection dropboxes A hierarchical model for permissions that supports a flexible approach to batch collections-based content management Customized thumbnails by taking a “snapshot” or specifying a timepoint Direct import of previously transcoded derivatives Avalon transcoding for multiple quality derivatives

15 0 – 3.1 Release functionality Integration with other enterprise systems Red5 and Adobe media servers Local authentication services (CAS, LDAP and others, using OmniAuth) Learning management systems, via the Learning Tools Interoperability (LTI) standard Support for LDAP group access control Support for persistent URL systems (PURL, Handle) Master files: leave, delete, or rename/move after transcoding Installation Easy installation and configuration via a virtual machine image and other methods Fully-transparent integration testing using travis-ci.org - every commit and pull request triggers a build Configuration approach for easier customization where possible

16 Upcoming releases (Fall/Winter 2014) Release 3.2 (December) Upgrade to latest versions of Hydra, Blacklight, and Bootstrap Metadata: adding language, original physical description, related item links, terms of use Let staff select multiple items and publish, unpublish, delete, set access permissions, assign to collection Release (January/February 2015) Import descriptive metadata from an Integrated Library System Import multiple quality levels of pre-transcoded derivatives

17 Release 4 (Spring 2015) Structural metadata – Import and store structural metadata – Allow users to navigate using media sections Prioritize media in the transcoding queue Bulk update of metadata Fedora 4 (testing?)

18 Beyond Release 4 Reporting and metrics Time limits for access IP restricted access APIs for ingest, analytics, metadata, etc. Fedora 4 migration Accessibility (navigability, closed captioning) Transcripts/Auxiliary items Improved metadata Playlists & clip making Integration with Wowza and Amazon Cloud Front Publish to YouTube or other systems Integration with Spotlight exhibits tool Internationalization

20 Community and future directions Multiple implementations currently underway – Stanford, UVa, UToronto, UT Austin, … Working on new features, including: – Structural metadata – Transcripts and captioning Starting to deal with code contributions Working with Hydra community – Leverage common features across “heads” – HydraDAM and Avalon, other preservation-specific integrations Sustainability/governance/business model Exploring hosted options

21 Sustainability and Governance Focus in 2015 with potential funder support Want to grow the number of implementers Ongoing costs of software support and development Potential revenue streams – Membership/sponsorship – Income from hosting – In-kind developer contributions Governance and management structure – Potential alignment with existing 501(c)(3) organization in higher ed open source community
