A presentation at Samvera Connect 2019, originally titled "Creating a new Carolina Digital Repository, customizations and change", described thus, and In June 2019, the University of North Carolina at Chapel Hill University Libraries Software Development and Repository Services departments launched the new Carolina Digital Repository (CDR) platform, built on Hyrax. The new repository houses scholarly materials in support of UNC’s Open Access policy and supports many existing workflows and use cases such as student papers, OA books, and datasets. In this presentation we will describe existing and new use cases and show how we customized Hyrax to meet those needs. We will also share lessons learned and future plans for the CDR.

Join us for an update on Avalon metadata in Hyrax. The Avalon Media System is an open source system for managing and providing access to collections of digital audio and video. The project is led by the libraries of Indiana University Bloomington and Northwestern University and is funded in part by grants from the Institute of Museum and Library Services and the Andrew W. Mellon Foundation. We are working to incorporate Avalon descriptive, technical, and structural metadata into Hyrax, the open-source repository front end from the Samvera Community, creating an AudiovisualWork that can be added to Hyrax as a gem alongside other work types (like GenericWork and Image). We will share our progress so far, including mappings for bibliographic import functionality and how things look different between Avalon 6 and Avalon in Hyrax. Avalon in Hyrax will also be available as a standalone Hyrax application so we are both letting the Hyrax in and letting the Avalon out! Come see how these two critters are getting along! and A presentation at Samvera Connect 2019 described thus

Many institutions need to import, export, and migrate data in bulk, and the ability to do this easily should be a fundamental service offered by any repository. For Hyrax, there are a range of home-grown and community solutions focused on specific use cases but there are no easily reusable community solutions. That’s starting to change and we’d like to talk about our specific experience building ‘Bulkrax’ and ‘Zizia’, two bulk import-export engines for Hyrax. This talk will outline the current status of our two projects, covering the design and approach taken, alongside features such as OAI-PMH import, and CSV import and export. We'll also talk about where Bulkrax and Zizia are going in the near future. We’ll show how each can be adopted, configured, and extended to meet local use cases, and how these projects are meeting the requirements set out by 2018’s ‘Batch Import-Export Working Group’. We’ll also discuss how best to move forward as a community around this issue, This will mean developing not only software but also shared community practice for managing the flow of bulk metadata from legacy systems and digitization projects into Samvera repositories., and A presentation at Samvera Connect 2019 described thus

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.

Since 2014, partners from Indiana University Bloomington (IUB) and Indiana University Purdue University Indianapolis (IUPUI) Libraries have been collaboratively developing new Samvera-based software to manage and deliver page turning digital objects. In 2018, conversations with Enterprise Scholarly Systems (ESS), a partnership between IUB Libraries, IUPUI Libraries, and University Information Technology Services (UITS), expanded our project's scope. This presentation will highlight our development efforts, now known as the ESS Images project or ESSI. In the past year, the ESSI team has developed numerous improvements to the Hyrax digital repository software. These improvements include the ability to order, structure, and label pages within an item, replicating features available in the Pages Online service launched in 2017. Additionally, the project has implemented optical character recognition search in a community-accepted way, building upon components of the IMLS-funded Samvera Newspaper Works application. We will also discuss upcoming improvements for our existing image collections. In these collections, images often have wildly different metadata profiles from each other. Our recent work has aimed to incorporate a model for flexible metadata developed by the Samvera Machine-readable Metadata Modeling Specification (M3) Working Group within Hyrax. We will be discussing the output of this work as well. and A presentation at Samvera Connect 2019 described thus

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.

As most Hyrax adopters know, Hyrax offers a basic set of metadata properties that it assigns to each new work type. Most adopters will extend that set, to a greater or lesser degree, adding new properties, defining vocabularies and terms lists, and setting other constraints and requirements. Adding new metadata is a complicated process in Hyrax, and there are various ways in which developers have worked to streamline things (eg. scooby snacks, dog biscuits and archetypes). But before we even get to customising a Hyrax application, metadata librarians and developers must collaborate on specifying the metadata requirements. With no community machine-readable approach to defining those requirements, misunderstandings are common, and can be costly. With a machine-readable specification for metadata, metadata librarians could accurately specify requirements and developers could validate and codify those into applications. That’s where the Machine-readable Metadata Modeling Specification (M3) steps in. The specification is the output of the M3 Working Group and is nearing its version 1.0 release. This presentation will provide a walkthrough of the specification, show how to construct and validate a new M3 profile, and illustrate the benefits of M3 for both metadata specialists and developers. and A presentation at Samvera Connect 2019 described thus

This presentation will explore the development of Hyku for Open Educational Resources — openly licensed educational materials such as textbooks, quizzes, classroom activities, etc. — while capitalizing on Hyku's multi-tenancy and sharing of infrastructure across two large groups of libraries. The PALCI and PALNI consortia (representing libraries in Pennsylvania, New York, New Jersey, West Virginia and Indiana) have just received a two year IMLS National Leadership Grant to develop Hyku into a multi-tenant, consortia-based service capable of handling OER in addition to other institutional repository resource types. In addition to leveraging collective expertise through consortia, two new work types are being developed for OER and electronic thesis and dissertations. This presentation will focus on the first work type being developed for OER , describing the features and uses of these resources, how the new work type model is being developed, and examine why Hyku and the Open Source Software community is a great home for this project. and A presentation at Samvera Connect 2019 described thus

A panel presentation at Samvera Connect 2019 described thus and As a Hyrax application developer, setting up a development environment is well documented within the community. Simply go through the Github README, install the prerequisites, and the development environment is practically ready to roll. Setting up a Hyrax production environment? Now, that’s a different story. Once an application is ready for production, there are a number of important decision points and configuration options that are less well documented within the community. This session will highlight some of those configuration options and include a discussion about how we can move forward, as a community, in communicating, sharing, and documenting how the characteristics of a repository should be considered before setting up a Hyrax production environment.

This will be a half-day, hands-on workshop covering data modeling primarily in RDF. We hope to bring a diverse group of Hydra community members together to learn, discuss, and build out examples that will inform Hydra community best practices for data modeling. This modeling work will be taught in the context of helping Hydra and Fedora development, metadata, and interoperability efforts. We will discuss how model uses a number of standards, and demo the different ways to represent models. We will compare and contract data modeling with metadata standards/profiles. We will walk through modeling efforts around PCDM and its place in our work and community - this workshop will not focus on PCDM alone (this is not a PCDM or RDF workshop).

A presentation at Samvera Connect 2019 described thus and Northwestern University Libraries (NUL) became a Hydra Partner in early 2012. Over the past 7+ years, we produced bespoke applications locally using the Hydra/Samvera codebase, worked on many iterations of a stand-alone grant-funded Hydra/Samvera product with another Partner institution, contributed effort to the development of Hyrax, implemented Hyrax as a component in a larger repository ecosystem, and shifted our repository services to the cloud. As we have evolved, we have gone through many changes in our local culture, in our user needs, in our codebase, and with our talent. One of the organizational culture changes is the shift of NUL to a learning organization. This change has made us more risk tolerant than in the past. It has allowed NUL to solve its local need of large-scale fast ingestion and description using novel approaches and technologies (Elixir, AWS services, Lambdas, etc). This presentation will discuss how these organizational changes and approaches to technology projects made us privilege the value of Samvera as a community of shared values and ideas over its shared codebase.
