Notas del editor
- Avalon Media System is an open source software system, originally developed by the libraries at Indiana University and Northwestern University, for managing and providing online access to large collections of digital audio and video for purposes of teaching, learning and research. Avalon was initially released in 2013, and as of early 2016, there are at least six adopters of Avalon but no consistent pathway for adopters to contribute financial or development resources to the project. In 2015, we were awarded a grant from the Mellon Foundation to create a long-term sustainability plan that includes better integration with the Hydra community, a strategy to increase adoption, and a pilot of a software-as-a-service (SaaS) offering in addition to its current locally-installed model. This presentation will provide an outline of Avalon’s path forward and how it corresponds with directions of the Hydra and Fedora communities. We are radically changing our development strategy as we move forward, and we will discuss our strategic initiatives and outline new areas of exploration and development. Additionally, we will talk about the advantages and disadvantages we have seen in our partnership model and how we plan to evolve that model as we move forward with Avalon’s development.
- This release is our last Fedora 3 release. It will provide a path for folks to migrate off Variations to Avalon (~11 institutions run Variations). The two major points for this release will be providing an ingest method (IU is currently in the process of ingesting our variations content into our production Avalon, ~10,000 of ~30,000 are currently ingested) and the playlist feature. Variations users will be forced to abandon Variations at some point in the nearish future because the next release of OS X will remove Quicktime's support for certain functions Variations need. These features have been deprecated for some time, but Apple is just now officially removing them. There also is not a supported version of Quicktime for Windows 10. So bad news for Variations but good news for Avalon adoption

- Watching Hybox as they go through some of these same issues. Release 7 (gemification) is too fuzzy at this point to discuss in detail. The next two releases are primarily architecture/rearchitecture focused, they will have some features, such as exhibits via Spotlight, dropping flash, and implementing an embeddable LTI player, but those features are primarily related to the promises made in our Melon Grant.
- We are not basing the next release on PCDM, instead we’re doing a direct port of our current models Migrating from Fedora 3 to Fedora 4 Fedora 4 running with our current data model (so datastreams, etc). Ensure no features in Avalon become nonfunctional during the upgrade
