- Description:
- A proposal for a presentation given at the Open Repositories conference in 2015 held in Indianapolis described thus, One of the many successes of the Hydra community is the fundamental notion from which its name is derived—the concept of many interfaces (“heads”) over top of a single repository (the “body”). The recent release of Fedora 4, with its internal RDF-centric model, has spurred efforts for a community-wide model of collections and works, such that the heads can be sure that the body will behave as they expect it to. That model has been designed and vetted by the Hydra community, and its architecture and initial implementations will be presented in this paper. [Note, and the subject of this proposal has since become known as the 'Portland Common Data Model'.]

- Description:
- Valkyrie is a new persistence layer for Samvera, designed to address performance and sustainability problems. It was developed through the existing Samvera Working Group process, showing that the current Samvera community governance structure can be used to tackle big problems. Valkyrie features pluggable persistence options, allowing Samvera applications to use not just the historical combination of Fedora and Solr, but also other options like Fedora or Solr by themselves, PostgreSQL, and local disk. Allowing Samvera applications to use different persistence options refocuses the Samvera community, shifting away from persistence in Fedora as the defining aspect of the community. Instead, the focus shifts to the shared tools built by the community. and A presentation at Samvera Virtual Connect 2018 described thus
