  • @DerVerschollene Existing video management systems like Kaltura and ShareStream support some of the online media management and delivery needs of academic libraries and archives but they are not flexible enough to support all of these needs. The Avalon Media System will provide support for deep description in the form of structural or time-based metadata, robust authentication and authorization, and integration with repositories providing services for long-term preservation--functionalities that academic libraries and archives need but current solutions do not address. We also plan to make Avalon interoperable with other popular video platforms so users can publish a video out from Avalon to Kaltura, YouTube, iTunes U, or a similar platform.

    Does that answer your question? I would be happy to provide additional details if that would be helpful.

  • On slide 8 it says that existing solutions are insufficient. Why is that?
    In what ways is it better than other video management platforms like Kaltura, ShareStream, etc.?

  • From F2F notes on the wiki (https://wiki.dlib.indiana.edu/display/VarVideo/Metadata+Decision+for+R1):Decision - MODS will be used for R1 for descriptive metadataBased on the following:Comparison between PBCore and MODS is fairly even for expected descriptive metadata elements in the system, but there is a difference in subject, where MODS allows for more  explicitly-faceted subjects than PBCoreExample:pbcoreSubject = Silent films -- France -- 20th centuryVSmods:subject     mods:topic = Silent films     mods:geographic = France     mods:temporal = 20th centuryMETS is being used for structural/content metadata, for R1, which means PBCore would not have instantiations, only descriptive metadataPBCore without instantiation is kind of pointless MODS is still recognizable and usableMODS can definitely happen for R1PBCore is something that can be created and added to the system later and is not necessary for the system we're building (at least in R1)Gives us more time to work in PBCore for technical metadata purposesOther metadata besides PBCore might be better for technical metadata - talk to partners about that; AES standards have better audio technical metadata but not necessarily video - requires investigationMODS allows for a language to be associated with an intellectual objectPBCore only allows a language to be associated with the instantiation so the intellectual object in PBCore would not be able to have any language(s) associated

  • Variations on Video:The Avalon Media SystemJon Dunn, Indiana UniversityMichael Klein, Northwestern University Digital Library Federation Forum November 4, 2012
  • About Us• Jon Dunn – Interim Assistant Dean for Library Technologies and Digital Libraries, Indiana University – Project Director, Avalon• Michael Klein – Senior Software Developer, Enterprise Systems, Northwestern University Libraries2 DLF 2012 11/4/2012
  • Agenda• Project overview and status• Demo• Release 1• Technical and metadata architectures• Plans beyond Release 1• How to participate3 DLF 2012 11/4/2012
  • 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: – September 2011 – October 2014• Partnership between libraries at Indiana University and Northwestern University4 DLF 2012 11/4/2012
  • Project Partners and Collaborators5 DLF 2012 11/4/2012
  • Project ObjectivesGoal: Create an open source system to enable libraries and archives toprovide 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 developers6 DLF 2012 11/4/2012
  • What needs are we trying to serve?• Libraries and archives (and museums?)• Wide variety of audio/video collections, uses, and access needs – Licensed educational video collections – Video/audio e-reserves – Archival collections – Open access collections• Research and teaching & learning use• Long-term management and access• Tie-in with preservation DLF 2012 11/4/2012
  • Existing Solutions Insufficient• Institutional and digital library repositories – DSpace, Fedora, Digital Commons, ContentDM• Web video services – YouTube, Vimeo• Streaming servers – Flash Media Server, Real Helix, Wowza, Red5• Classroom lecture capture – Echo360, Mediasite, Opencast Matterhorn• Digital asset management systems – OpenText, NetXposure• Online video environments – Kaltura, Brightcove DLF 2012 11/4/2012
  • Project Progress• Most of development team hired• Trained on agile development (Scrum)• Community demo releases: – Release 0, July 2012 – Release 0.5, October 2012• New name• Active participation in Hydra and Matterhorn communities9 DLF 2012 11/4/2012
  • Current Activities• Northwestern hiring one more developer• Website design• Marketing and communication planning• Release 1 development• Metadata and object modeling10 DLF 2012 11/4/2012
  • Development TeamIndiana University Northwestern University• Jon Dunn, project director • Stu Baker, project director• Chris Colvard, lead developer • Steve DiDomenico, scrum master• Phuong Dinh, developer • Stefan Elnabli, metadata/preservation specialist• Julie Hardesty, metadata analyst • Michael Klein, lead developer• Brianna Marshall, project assistant • Karen Miller, metadata analyst• Mark Notess, product owner/manager • Julie Rudder, product owner• Nathan Rogers, developer • Claire Stewart, product owner/director • Andrea Zielke, project assistant 11 DLF 2012 11/4/2012
  • Demo12 DLF 2012 11/4/2012
  • Release 1• Expected in February 2013• Goal is to support installation and piloting by partners• Functionality • File upload, transcoding & descriptive metadata: manual or batch • Batch loading via dropbox and tabular data file • Authentication and authorization – optional integration would require use of LDAP or some minor programming • Red5 and Adobe Flash media server support • Discovery via Blacklight faceted search & browse • Playback on desktop browsers & mobile devices (iOS & Android) • Basic monitoring & troubleshooting13 DLF 2012 11/4/2012
  • Release 1 Pilot Support• Distribution packages • Both source distribution and some form of preconfigured package, e.g. VM image• Installation & configuration documentation• Email support• Advice on hardware & software requirements by Jan 1 • Goal: Small pilots/tests can be run on one server or VM; larger scale use may require distributing functions across multiple machines• Content & metadata from pilots can be migrated forward to future versions14 DLF 2012 11/4/2012

  • Authentication• OmniAuth • Multi-provider authentication middleware for Rails applications • Providers are known as “strategies” • Dozens of turnkey “provider strategies” including Google/Google Apps, Facebook, Twitter • Easily customizable “developer strategies” exist for CAS, LDAP, Shibboleth, OAuth/OAuth2, OpenID, Kerberos, and many others • As long as the provider returns an email address, Avalon will identify the user DLF 2012 11/4/2012
  • Metadata for R1• Descriptive metadata • MODS• Structural/content metadata • METS• Technical metadata • Will be a focus after R1• Still looking at PBCore, for technical metadata and/or as an export format17 DLF 2012 11/4/2012
  • Beyond R1• Releases every three months• Workflow & batch loading improvements• Authorization improvements• Structural metadata for navigation• Playlists and clip making• Easy player embedding• Transcripts• Publishing out to other systems• More optimization for mobile• Focused accessibility work• We want to know what your priorities are!18 DLF 2012 11/4/2012
  • Help with Requirements• Survey: – Media server – Authentication methods – Metadata – Media formats – Distribution packages – Importance of VM image Take the survey: http://tinyurl.com/AvalonWebinarSurvey19 DLF 2012 11/4/2012
