A recording of a panel presentation at Samvera Connect 2018 described thus and In this panel we will briefly discuss the current landscape of needs and reasons for users to consider moving from an established repository, and the challenges facing users of a variety of platforms, both cultural and technological. We will also consider work currently underway such as "Bridge to Hyku", a grant-sponsored project empowering Content DM users to migrate, successes in DSpace-to-Samvera migration and what's on the horizon for BePress. In discussing these challenges, we hope to present the Samvera Community with an opportunity to grow the portfolio of users and create the potential for standards and teams to assist those who wish to be a part of the Samvera Community.

A recording of a presentation at Samvera Connect 2018 described thus and Panelists from Duke University, Indiana University, and the University of Michigan will share their experience of developing a Research Data Repository based on Hyrax 2. They will discuss what worked out-of-the-box, what was customized, future directions, lessons learned to date from working together, and contributing back to the Hyrax community. Institutions’ efforts include data migration, accessibility testing, branding, community outreach, curation workflows, and overcoming the challenges associated with large datasets.

A recording of a presentation at Samvera Connect 2018 described thus, prototyping a core component of our new architecture to be horizontally scalable, designing a new architecture for our digital library with a wide ranging set of requirements and users, Stanford University Library has a robust digital library system called the Stanford Digital Repository. This repository holds a little under 500 TB of materials in preservation, and a little less than that for online access, from our cultural heritage digitization efforts and institutional repository outputs. These materials are managed across 90+ codebases serving a variety of functions from self-deposit web applications, to a nearly 10 year old parallel processing framework, to a digital repository assets publication mechanism leading into our Blacklight, Spotlight, and Geoblacklight applications - among other services and needs. At the core of this system is a Fedora 3 store. With Fedora 3 now end-of-lifed, and our system suffering from limited to no horizontal scalability options, we’re revisiting our system and architecture. We are writing it from the start with a goal to have data-forward, distributed microservices and some event-driven processing components. TACO, our new core management API, is the heart of this new architecture, and is currently being developed as a prototype. This talk will walk through the process of analysing our current system via a dataflows analysis, then planning how to create ‘seams’ in our current system to migrate towards our new system in an evolutionary fashion instead of a turn-key migration. A video recording of this session is available at the 'Related URL' below., and seeing where community technologies like Hyrax, Blacklight, and IIIF will connect
At Stanford libraries we've run hundreds of virtual machines to support dozens of applications. We've found the cost and complexity of patching and maintaining these machines to be untenable. We believe that a serverless infrastructure is our future and so we are using AWS Fargate (Elastic Container Services) and Lambda architecture to reduce our maintenance burden. We will explain the AWS offerings in this space, explain how we can set up a simple distributed system, and point out pitfalls that we've experienced. and A video recording of a presentation at Samvera Connect 2018 described thus

A presentation given at Samvera Connect 2018 described thus, An overview of modern front-end UI component architecture and patterns. Will showcase case studies in development and implementation decisions in Avalon Media System (platform, React/Redux application built on top of Hyrax in AWS). Will make a case for why UI component architecture is important in community-driven, open-source development, how it can directly benefit the Samvera community moving forward.

A presentation given at Samvera Connect 2018 described thus, Despite widespread interest in Hyrax, Samvera’s new flagship repository solution, there is a dearth of documentation about how to run a production instance. We’ll cover the lessons we’ve learned from a year of building and hosting Hyrax, including our new project checklist, logging and monitoring practices, and data migration paths. DCE has been hosting a Hyrax based ETD repository for Emory University for 12 months. We've made a lot of discoveries and improvements since we launched. We'll be sharing our learnings and best practices for running Samvera Based repositories including, and * Infrastructure as code (esp. ansible for configuration management) * Monitoring using open-source and commercial tools (nagios, ok computer, splunk, pingdom, honeybadger) * Maintenance, Upgrades, and Testing A video recording of this session is available at the 'Related URL' below.
Over the past two years, Northwestern University Libraries has moved its repository infrastructure and applications to Amazon Web Services. Our initial solution, presented at Samvera Connect 2017, involved AWS CloudFormation, several different deployment platforms, and a lot of manual intervention. In our second phase, we have adopted a fully automated build/configure/deploy system to stand up Fedora, Solr, PostgreSQL, Redis, a Cantaloupe IIIF server, an Avalon Media System instance, a secure CloudFront streaming media distribution, and two Hyrax applications using Terraform, Docker, AWS Elastic Beanstalk, and a whole bunch of homegrown tools and hacks. This presentation will provide an overview of our current system, and hopefully jumpstart some discussions of how these tools can be adopted, standardized, and reused among other members of the Samvera community.

This presentation aims to explore the possible integration of Samvera digital object repositories with additional web services using message brokers. There have been cases in which it is necessary to synchronize content updates between repositories and additional library systems such as library catalogs or digital exhibit publishing software. Within this context, developers may benefit by exploring architectural pattern in which a dedicated message broker receives asynchronous notifications of repository content updates, new ingestions, and deletions. In response to having received these messages, the broker may then broadcast these events to other listening library systems. The library systems then may reindex or update their own content accordingly. A conceptual overview of this architectural pattern shall be provided, followed by an overview of an implementation local to the systems within the Princeton University Library (synchronizing content between implementations of Valkyrie and Spotlight using RabbitMQ). The outcome of this presentation would be to identify other Samvera adopters who may also be utilizing message brokers, with the ultimate aim of determining whether or not this approach would be beneficial to a larger number of community members.

A presentation prepared for Samvera Connect 2018 described thus and Ever wonder how modules work, and what all those include's, extend's, and prepend's are doing differently in gems? I did, and I found out, so I'd like to share. Unfortunately, the presenter was unable to attend the conference and the talk was not actually delivered.
This talk will present a project at the University of Hull, working with CoSector and Cottage Labs, to create a permanent digital archive of the Hull City of Culture. Hull was awarded UK City of Culture for 2017 and, throughout the year, generated a wealth of digital material documenting the events and activities celebrating the city, as well as archives from the organization and evaluation of the event. The University of Hull, already an active user of Samvera technologies, wanted to build on the work done for the Jisc ‘Filling the Digital Preservation Gap’ by using Archivematica for the digital archives preservation pipeline and Hyrax as a showcase for the City of Culture. We will also talk about how the project was originally conceived, and how that has changed through active and engaged project meetings to reflect ongoing service needs for the management of digital archives, of which the City of Culture archive forms a part. Integration with CALM (archives management solution ) and the existing Hull History Centre Blacklight catalogue (developed by DCE) is being explored to create a fully integrated digital archiving solution.
