- Description:
- however, all of Rail's most common UI elements and features will be retained. If time permits, we will also add Blacklight as a dependency for search and retrieval., How Valkyrie differs from ActiveRecord How to manage the differences between Valkyrie and Rails while retaining most of Rails' common features In this workshop, participants will learn how to build a simple Rails application using Valkyrie as a dependency. Data will be persisted with Valkyrie's data mapper pattern and not with ActiveRecord, and Slides from a workshop given at Samvera Connect 2019 and described thus

- 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, supporting multiple backends for storing files and metadata. Currently supported backends include Fedora, PostgreSQL and Solr for metadata, and Fedora and local disk for files. Valkyrie provides an abstraction layer over file and metadata persistence, allowing an application to be configured to use different backends without code changes. This workshop will include, Description, A workshop given at Samvera Connect 2018 described thus, and An overview of Valkyrie's design, including why the Data Mapper pattern was used, and how Valkyrie addresses sustainability issues with ActiveFedora Status updates on current Valkyrie development, including applications built using Valkyrie, and efforts to use Valkyrie in Hyrax Hands-on exercises to give attendees first-hand experience working with Valkyrie and demonstrate how concepts from Samvera applications work with Valkyrie
