A presentation given at Samvera Connect 2018 described thus and A presentation about Penn State's new Valkyrie project that will replace ContentDM. I will discuss our progress thus far, with particular attention to accessibility and performance, two of the principle concerns in our development process. Additional topics will include issues with Valkyrie and the importing process we are using with data from ContentDM. A video recording of this session is available at the 'Related URL' below.
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
