A presentation given at Connect 2017 described thus and Presentation on a gem for Hyrax models and authorities, which provides a central place for creating models for different types of works. Each new model draws on a central pot of properties to declare the set of properties needed to fully describe the particular work. The gem already exists and has sample models for journal article, thesis and more. In this presentation we will work through the process of defining a new model and then using that model in a Hyrax application. The idea behind the gem is to make it easier for developers to deploy new models, and provide a place for metadata folks to jointly define re-usable models.

A presentation given at Connect 2017 described thus and Princeton University Library has spent the last two years developing Plum as a staff-only ingest platform for books, manuscripts, geo-spatial data, and archived ephemera. This talk would go through a history of the design goals, the successes we've had, the problems we've run into, and a look into the future.
A presentation given at Connect 2017 described thus, it’s not fun to have an ingest fail overnight and spend the morning tracking down why. Programmatically testing and validating digital object metadata prior to ingest helps us avoid these failures. The metadata itself is managed by Git and stored in GitHub, Several years ago UCSB incorporated Git/GitHub and JIRA into our metadata management and batch ingest workflows. Since then we’ve looked at repurposing other development tools to provide lightweight and automated solutions to problems we often face. One is that we rely primarily on batch ingests when adding content to our Samvera repository. As a result it’s especially important for the metadata to be error-free, and this allows us to run automated checks against any changes using Jenkins and some custom libraries we’ve written for validating CSV and MODS metadata. In this session, we will provide an overall of our current ingest preparation workflow and the tools we are using, and will discuss some of the benefits that have come out of this collaborative effort.

A presentation given at Connect 2017 described thus and In this presentation, we present Fedora 4’s performance in different use cases. These use cases are the most general use cases that were developed by the Fedora 4 performance team. We compare the performance between different versions of Fedora 4 and demonstrate the improvement between these versions. We will also describe the procedures of these performance experiments and demonstrate the software we use (Ansible, AWS, and JMeter). Our performance experiments are conducted in the AWS ecosystem, and we use an R graph tool to visualize the JMeter result. With the AWS grant, we can do many different performance experiments in many scales. Moreover, it is easy to repeat and verify the performance results using AWS. The Fedora 4 performance team wants to know more about the Samvera community’s interests related to the Fedora 4 performance. We plan to gather more use cases from the Samvera community, including middleware such as Solr, Camel, and Fuseki, etc. We can investigate, explore issues, and continue enhancing the future of Fedora 4.

Valkyrie is a new persistence layer for Samvera, designed to address performance and sustainability problems. It was developed through the existing Samvera Working Group process, showing that the current Samvera community governance structure can be used to tackle big problems. Valkyrie features pluggable persistence options, allowing Samvera applications to use not just the historical combination of Fedora and Solr, but also other options like Fedora or Solr by themselves, PostgreSQL, and local disk. Allowing Samvera applications to use different persistence options refocuses the Samvera community, shifting away from persistence in Fedora as the defining aspect of the community. Instead, the focus shifts to the shared tools built by the community. and A presentation at Samvera Virtual Connect 2018 described thus

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 2019 described thus and What if the Hyrax web application were to support and include, by default, controlled vocabularies from marginalized communities? Currently Hyrax supplies a default set of descriptive metadata fields for describing uploaded objects. This set of fields includes Keyword (a required field) and Subject (an optional field). Neither of these fields are controlled by a vocabulary of terms upon install. The Questioning Authority (QA) gem exists as an option to configure and apply controlled vocabularies for use with fields such as these in Hyrax. While QA can be configured to work with nearly any vocabulary, the current vocabularies offered through the gem when it is installed include LCSH/NAF/GFT/MPT/DGT, FAST, Geonames, MeSH, Agrovoc, DBPedia, NALT, and Getty (AAT, TGN, ULAN). These are widely used mainstream sources for topical subject and genre description but also tend to reflect the current dominant mainstream power structure in the United States (white, male, straight, able-bodied, middle-class, Christian, Anglo). Should we increase the list of vocabularies available, by default, in the QA gem? Should we go beyond that and enable vocabulary choices on the default Subject and Keyword Hyrax fields? This lightning talk will discuss these questions and consider vocabulary options that would provide more inclusive descriptive capabilities.

The Hydra Project started in 2008 through a partnership between the University of Hull, the University of Virginia, Stanford University and Fedora Commons (now DuraSpace) to create tools that support use of the Fedora digital repository. Hull adopted the software outputs from this collaboration for its institutional repository in 2011 and remains an active Partner in the community, serving on the Steering Group and fostering development of the community and software in the UK and mainland Europe and The community now has 35 formal Partners and over 70 known adopters internationally. In June 2017 Hydra changed its name to Samvera, Icelandic for 'being together', to recognize the value gained from multiple institutions working together to create the underlying common basis upon which multiple different repository solutions have been implemented. Samvera can be adopted through a set of tools to develop your own repository (using a package called Hyrax as the starting point) and is also available as a complete repository solution, hosted or local, through the use of Hyku. The community has been at the heart of making Samvera a success, and will continue to underpin its future direction.
