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
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
