- Large ingestion of 4 gig tifs with derivates and preservation checks (10k works) in ~ 1 hour - 5k batch metadata updates ~5 minutes - Round trip spreadsheet update (5k records in 5 minutes) - Preservation dashboard / verification - Local authority creation and updates This presentation will discuss the process, what we learned, and how it relates to the Samvera community at large. and On St. Patrick's Day NU went live with our new digital collection repository and asset management tool prioritizing speed of ingestion and metadata updates. We reframed the problem by working with end-users to look closely at workflows and prioritize solutions rather than any specific technology. The resulting application ecosystem is extremely budget friendly and the architecture supports
Heavily inspired by QA, "Authoritex" is a Hex package for querying any controlled vocabulary or set of authority terms that NUL developed for use within our Elixir ecosystem. We'll go through quick overview of Authoritex and how it fits into our repository ingest application "Meadow" and our broader strategy for handling controlled terms and authorities.

This presentation will focus on describing why we chose this path and the decisions and tradeoffs we've made along the way, along with a brief demonstration of our current state. The 'Related URL' below links to beginning of this presentation in the day's YouTube recording., Northwestern University Libraries has been building a "green field" digital repository application since June 2019, code-named "Meadow". Our goal in building Meadow is to provide an internal tool to ingest, modify and publish digital resources to an API that drives our user-facing digital collections frontend. Meadow's development roadmap has focused on complementing NUL's existing production workflows and implementing best practices in digital preservation in a cloud-based environment. Meadow is built with a several languages, tools, and frameworks including, and A presentation given at Samvera Connect 2020 On-line described thus

A presentation given at Samvera Connect 2020 On-line described thus, using a recent major batch update feature as a case study. We’ll explore how our approach allowed us to stay connected to our users and helped keep our development team in sync. Finally, we’ll reflect on what we’ve found most successful in this approach as well as stumbling blocks we encountered along the way. The 'Related URL' below links to beginning of this presentation in the day's YouTube recording., and Over the past year, NUL dev team has implemented and refined a workflow for modular development of repository applications. It starts with addressing a specific user need or problem. Using design-thinking techniques, we next generate visual solutions through rudimentary wire framing, white boarding sessions and architecture discussions. We then move to API design and mocking before starting development with two teams working independently, from the API, outwards. This presentation will demonstrate the iterative approach in action

Forking this Github starter project spins up a webpack React dev environment, along with some tools and commands to bundle your React component to share via NPM. An alternative to Create React App, the project configuration was developed with the aim of exporting and sharing with other React apps in the wild.

A lightning talk at Samvera Virtual Connect 2019 described thus and Avalon Media System is upgrading it's UI component for handling structural metadata editing for an audio or visual work. The user can select and organize timespans in an AV work by manually typing bounding times and titles, or by interacting with a visual representation of the waveform. Technologies used are Peak.js and ReactJS.

Northwestern University Libraries is currently running Samvera applications in production. Three of these are developed, maintained, and managed by the Repository & Digital Curation workgroup, * Arch, an Institutional Repository, based on Hyrax 2.4.1 * AVR, Northwestern's audiovisual repository, based on Avalon 6.3 * DONUT, the staff-facing ingest interface for the digital object repository, based on Hyrax 2.4.1 In developing and deploying these applications, we have encountered (and mostly overcome) numerous stumbling blocks relating to performance, scalability, customization, and assumptions about the deployment environment and infrastructure on which the apps will run. While we have found it possible to shoehorn the Samvera stack (as it exists today) into our Amazon Web Services cloud-based deployment environment, we have also started to investigate the rewards and compromises involved in taking a cloud-first approach to our next generation of tools. We have identified several basic tenets for this approach so far, * If AWS offers a native Software-as-a-Service (SaaS) solution for a particular problem, use it (e.g., choose ElasticSearch/Cloud Search over Solr) * Avoid virtual server instances that run 24x7 waiting for requests/work * Do not assume there is a local filesystem to work with * Optimize startup time so that units of work can be spawned and killed as needed * Constantly assess and reassess every unit of work for scalability, repeatability, and idempotence * Keep data portable and code adaptable, but don't over-stress about vendor lock-in In this presentation, members of the Repository Development & Administration Team will present on lessons learned from 7 years of working with Samvera, Avalon, and Hyrax, what the future holds for our next round of in-house development, and the opportunities & compromises our cloud-first approach creates regarding our use of and contributions to the larger Samvera community., and A presentation at Samvera Virtual Connect 2019 described thus

A lightning talk at Samvera Virtual Connect 2018 described thus and Avalon Media System is working towards a release to integrate with Hyrax in support of time-based media formats. This includes creating a Work type to support the needs of audio and video formats and provide an upgrade path for those who have been using Avalon in it’s previous releases as a standalone Samvera product. Join us for a look at the new Audiovisual Work type, specifically how we’re transitioning descriptive metadata from MODS XML to RDF.
