3 Avalon Project Objectives Goal: Create an open source system to enable libraries and archives to provide online access to video and audio collectionsDigital audio/video management and delivery system, focused on needs of libraries and archivesFollow an agile, open source development modelLeverage existing technologies, where feasibleCommunicate and market the project broadly to increase awareness and grow the community of users and developers
4 Project OverviewFunded in part by a National Leadership Grant from the Institute of Museum and Library ServicesOriginal name: Variations on VideoPlanning grant:August 2010 – July 2011Implementation grant:October 2011 – September 2014 September 2015Partnership between libraries at Indiana University and Northwestern UniversityDiscuss motivations
8 Why Avalon?Existing repository systems don’t work well for time-based mediaDSpace, Fedora, Digital Commons, ContentDM, …Issues: integration with streaming servers; hard to support time-based navigation; difficulties in integrating access controlExisting media systems don’t work well with repositoriesKaltura, Brightcove, Ensemble, ShareStream, …Issues: focus on short-term access for teaching and learning; limited metadata and access control capabilities; integration with preservation workflowsStrong desire for community-based solution

14 0 – 3.1 Release functionality End-user functionalityFaceted discovery for search and browseVideo and audio playback in browsers or on mobile devicesStream-level securityAbility to embed media player in other websitesPersistent URLsRTMP and HTTP streaming, Flash and HTML5-based playerCollection managementInteractive or batch uploading of media files and MODS metadataPrivate collection dropboxesA hierarchical model for permissions that supports a flexible approach to batch collections-based content managementCustomized thumbnails by taking a “snapshot” or specifying a timepointDirect import of previously transcoded derivativesAvalon transcoding for multiple quality derivativesClaire?
15 0 – 3.1 Release functionality Integration with other enterprise systemsRed5 and Adobe media serversLocal authentication services (CAS, LDAP and others, using OmniAuth)Learning management systems, via the Learning Tools Interoperability (LTI) standardSupport for LDAP group access controlSupport for persistent URL systems (PURL, Handle)Master files: leave, delete, or rename/move after transcodingInstallationEasy installation and configuration via a virtual machine image and other methodsFully-transparent integration testing using travis-ci.org - every commit and pull request triggers a buildConfiguration approach for easier customization where possibleClaire?
17 Release 4 (Spring 2015) Structural metadata Import and store structural metadataAllow users to navigate using media sectionsPrioritize media in the transcoding queueBulk update of metadataFedora 4 (testing?)Mark

23 Avalon replaces this system and does more Avalon replaces this system and does more. We launched a pilot in Summer 2013, support a few course and we went live.
24 Use Cases Course Reserves – restricted access Archival Collections MMLC – video management by unitsoutside the library
25 Future Additional units outside the library? Integration with other campus media solutions?Better integration with Ares Course Reserves?
