design course projects, – Faculty: Observational research, fine arts performances, – Online learning initiatives: lectures, course reserves– Administration: Office of Development, Oral history program,
campus events

items at SMPL (13,000 and counting)– Satisfying requests by researchers (remote and on-site) for
online access to collection material
What other media solutions do you
have in place that Avalon replaces or
complements? • Will replace existing streaming infrastructure
(wowza) that is outdated and not integrated with SUL’s digital library discovery environment
• Will complement outsourced CDN services used for boutique collection web sites
• Will complement current Drupal infrastructure and future Spotlight exhibits, where curators and other librarians promote media collections and services through web sites
• May play into course management system currently in transition (from Sakai to Canvas)
Where are you on your
implementation or evaluation?
• Evaluation is complete, including a test installation of Avalon Release 2 in Fall 2013
• Currently interviewing for Media Infrastructure Engineer to lead the design, installation, and integration (2 year project starting approx. January 2015)
What staff resources have been
necessary to implement Avalon at
your institution?
• Parts of
– Product owner
– Service manager
– Software developer
– Infrastructure engineer
– System / Storage Administrator
– DevOps Systems configuration
What features do you most need
that are not currently in Avalon?
• Support for Wowza streaming server• Support for Open Annotations• Support for transcripts/captions: synchronization and
full-text search• Support for PBCore metadata (v2)• Integration with Fedora 4• IP-based access control• Hooks for capturing special license terms• Re-architecting Avalon as components that can be built
into a digital library ecosystem, instead of a tightly integrated out of the box solution
What would you like the Avalon
community to look like in the future?
• A healthy cadre of core developers/maintainers; the media space is always evolving and Avalon will need to keep up
• A vibrant, connected user community that reflects the requirements of scholars who use media in research and teaching
• Vendors who can help small installations with local implementation or offer hosted services
