Featured Presentations
A demo of the new collections features in Hyrax 2.1.0
Lynette Rayle (Cornell University)
Live demo - no slides (see recording)
Abstract:
Audience: repository managers, developers
Valkyrie
Esmé Cowles (Princeton University)
Abstract: 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.
Audience: repository managers, managers of developers, others involved in open source community decision making
Actor Refactor Contractor
Tom Johnson (Data Curation Experts)
Abstract: The 'Actor Stack' is an important but little understood point of extension in Hyrax and CurationConcerns applications. This talk will explore the actor stack through a critical lens. Questions addressed include: How does the stack work? How can I best approach customization? What are the pain points? How did we get here? Where might we go next?
Audience: developers
Lightning Talks (7 minutes each)
An Update on the Hyrax Roadmap
Steve Van Tuyl (Oregon State University)
Tom Johnson (Data Curation Experts)
Abstract: At Samvera Connect 2017, we presented a draft roadmap for the Hyrax 2.x-3.x release series. Since then, much work has been done to fulfill the promise of that roadmap, and work continues. In this talk we'll quickly review the roadmap, discuss the current status of work on Hyrax, and call for participation in future development efforts to bring Hyrax to 3.0 as soon as feasible.
Audience: repository managers, developers, Hyrax users
Taking the self out of self-deposit: adapting Hyrax for mediated deposit of research data
Moira Downey (Duke University)
Will Sexton (Duke University)
Abstract: Over the course of the last six months, Duke University Libraries have been engaged in adjusting some of the native features of Hyrax in order to support a research data curation workflow that is heavily mediated and may involve extensive pre-publication alterations to files and their arrangement or description. This presentation will cover how we've adapted a Hyrax application to facilitate research data curation best practices, using the FAIR (findable, accessible, interoperable, and reusable) data guidelines as a framework.
Audience: repository managers, research data curators
Avalon’s Audiovisual Work in Hyrax: It’s about time
Jen Young (Northwestern University)
Abstract: 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.
Audience: metadata, developers
Now out on Betamax: IIIF Presentation 3.0
Chris Colvard (Indiana University)
Adam Arling (Northwestern University)
Abstract: IIIF Presentation 3.0 pushes beyond only images to support time-based media. This presentation will explain the new possibilities and how the Avalon team is helping to bring those to Hyrax.
Audience: repository managers, metadata, developers
Bridge2Hyku: Building a Migration Toolkit
Todd Crocken (University of Houston)
Abstract: Bridge2Hyku is an IMLS-funded grant project that is building a migration toolkit to assist institutions interested in migrating their digital content to Hyku. The toolkit contains general guidance for migration planning, documentation for software that enables efficient and effective data migration, and an introduction to the Hyku platform. This presentation will provide an overview of the project goals and timeline, an update on project progress, and information about how to contribute to the Bridge2Hyku migration toolkit.

| 11:18 - 11:21 | Samvera Fundraising Working Group Update Karen Cariani (WGBH) | An update on the activities of the Samvera Fundraising Working Group. | All Audiences |
| 11:22 - 11:25 | Samvera Marketing Working Group Update Chris Awre (University of Hull) | We wish to share the ongoing work of the Samvera Marketing WG following its initiation in 2018. The goal for this year is to raise awareness of Samvera amongst different audiences that Samvera works with, both within our organisations and with potential new members of the community. Ideas, as ever, of what sells Samvera for you are welcome! | All Audiences |
Presentation #1 | 30-minutes (including Q&A) | ||
| 11:26 - 11:56 | M3 and Hyrax: Bringing Flexible Metadata to the Samvera Community Randall Floyd (Indiana University) Julie Allinson (Co-Sector) Ned Henry (UC Santa Cruz) | If you’re a developer or metadata specialist involved in building or managing a Hyrax based application, you may have discovered that developer time is required just to add new fields to Work Types or alter the behavior of existing fields in Hyrax edit forms and views. There are currently no features within Hyrax that allow for easy configuration-based metadata, so changes are required in multiple places to the code to accommodate needs beyond the core profile provided. This presentation will provide a glimpse into collaborative work currently underway that could be used as a basis to solve this problem for the Samvera community. We will begin by summarizing some individual efforts to introduce "configurable metadata", such as Houndstooth, Scooby Snacks, Dog Biscuits, and Archetypes. We will then touch on the collaborative team that has emerged from those efforts - the Machine-readable Metadata Modeling Working Group, or M3 - which is currently working to develop a draft specification for a common format for metadata modeling. Finally we will provide an overview of how this specification could be used to develop a common feature to allow for more flexible and configurable metadata in Hyrax. | Developers, Metadata Specialists |
Day 1 Lightning Talks | 7-minutes each | ||
| 11:57 - 12:04 | Rethinking metadata design and management Arwen Hutt (UC San Diego) Ruth Tillman (Penn State) | For metadata specialists, creating metadata profiles, system requirements, and accompanying documentation often feels like a game of whack-a-mole. Current practices and technologies also mean comparing your profiles with another institutions’ is an enormous hassle. To address this problem, developers and metadatists came together to create the machine-readable metadata modeling (M3) specification. This presentation will offer some history and use cases for the specification, an update on its current status, and where to learn more. | Metadata Specialists |
| 12:05 - 12:12 | Making Hyrax more inclusive through controlled vocabulary choice Julie Hardesty (Indiana University) | 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. | Developers, Repository or DAMS Managers, Metadata Specialists |
| 12:12 - 12:20 | From Institutional Repository to Digital Collections Management: Replacing CONTENTdm with Samvera/Hyrax Kathryn Michaelis (Georgia State University Library) Jon Bodnar (Georgia State University Library) | Since May 2018, the Georgia State University Library has been developing an instance of Samvera/Hyrax to replace CONTENTdm for digital collections management. After using CONTENTdm for more than a decade, certain features have become indispensable to our digital collections’ workflow. A key part of our development effort has been deciding which features to build into (or to remove from) Samvera/Hyrax. In this presentation, we will discuss how we have balanced updating and preserving workflows, and we will review some of the features we are implementing, including support for controlled vocabularies, oral history ingest and display, and bulk uploading. | Repository or DAMS Managers, Metadata Specialists, Administrators |
| 12:21 - 12:28 | Introducing NewspaperWorks Eben English (Boston Public Library) | This talk will discuss NewspaperWorks, a gem that provides content models, batch ingest tasks, and front-end functionality for digitized newspaper content. The gem is intended to be installed in a Hyrax-based repository application, and can be used to add newspaper content to an existing repository, or create a stand-alone newspaper content interface. | Developers, Repository or DAMS Managers, Metadata Specialists, Administrators |
| 12:29: - 12:36 | Avalon Media System Update Jon Cameron (Indiana University) David Schober (Northwestern University) Ryan Steans (Northwestern University) | This presentation will cover Avalon progress from the past year focusing on new features that will be available in both Avalon 6 and 7. In addition to discussion of core components such as Batch Ingest, Transcoding, and IIIF manifest generation, the team will showcase new features available on Avalon 6 (with eyes toward 7) such as OHMS integration, the Timeliner and the Structural Metadata editor. We will give an update on planned work such as design for Avalon 7, playlists, user management features, and permissions as we work toward building Avalon 7. | DevOps and System Administrators, Repository or DAMS Managers, Metadata Specialists, Administrators |
| 12:37 - 12:44 | Structural Metadata Editor component for audio and video clips Adam Arling (Northwestern University) Dananji Withana (Indiana University) | 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. | Developers, Repository or DAMS Managers, Metadata Specialists, Administrators |
| 12:45 - 12:54 | Hyku: a multi-tenant, ready-to-ship Samvera implementation Kevin Kochanski (Notch8) | An introduction to Hyku. Hyku is a collaborative product that extends existing Samvera codebase in order to build, bundle, and promote a feature-rich, robust, flexible digital repository. Hyku's chief benefits are ease of installation, configuration, and maintenance. | Repository or DAMS Managers, Administrators |

| 11:06-11:36 AM EDT | Samvera headaches: the choice between flexibility and ease of maintenance with multiple and multipurpose repositories Richard Higgins (Durham University Library) Olli Lyytinen (Durham University Library) | The presentation would start with a demonstration of the Samvera heads that we have developed for deploying and managing IIIF at Durham, looking particularly at what has worked and what has stretched the underlying Fedora repository to breaking point. In parallel we have developed a research data system based on Sufia and have now reached the stage where we need to either bring these systems together into a single package, or identify a clear break between where we should follow standard packages such as Hyrax and where local implementations are required. With developments like Valkyrie and the Oxford Common File System also imminent, it becomes tempting to just wait until they are released, further complicating the planning process.
| Developers, DevOps and System Administrators, Repository or DAMS Managers |
Day 2 Lightning Talks | 7-minutes each | ||
| 11:40-11:47 AM EDT | Pairing: why, when, how Anna Headley (Princeton) | I'll present the many contexts in which pair programming can be beneficial in different ways, reasons to use pairing as part of the regular practice of your team, the basic mechanics of how pairing works, prompts for staying mindful of power dynamics while pairing, and ideas for introducing the practice to a team that has never really done it before. | Developers, Administrators |
| 11:48- 11:55 AM EDT | Fedora 6.0 and the Oxford Common File Layout David Wilcox (DuraSpace) | For the past several years the Fedora community has prioritized alignment with linked data best practices and modern web standards. We are now shifting our attention back to Fedora's digital preservation roots with a focus on the Oxford Common File Layout (OCFL). The OFCL is an application-independent approach to the storage of digital objects in a structured, transparent, and predictable manner. Fedora 6.0, the next major release, will replace the current ModeShape backend with a more scalable and performant implementation that persists data in accordance with the OCFL specification. This presentation will provide an overview of the Fedora 6.0 design, including an introduction to the OCFL and how it will be implemented. It will be of interest to Samvera community members who want to track Fedora developments and understand their impact on Samvera applications. | Developers, Repository or DAMS Managers |
| 11:56- 12:03 PM EDT | Valkyrie Update - 2.0 and beyond Trey Pendragon (Princeton University) Carolyn Cole (Princeton University) | This will be a shorter presentation to give an update on changes to Valkyrie since Samvera Connect, as well as provide some guidance on when 2.0 will be released and what to expect. | Developers, Administrators |
12:04- 12:11 PM EDT | Timeliner tool in Avalon Chris Colvard (Indiana University) Brian Keese (Indiana University) | The Timeliner is a pedagogical tool that was available in the old Variations application, the Avalon predecessor. It allows for a visual representation of the structure of an audio file or fragment. The tool, which will be made available as a standalone, has been reimplemented using IIIF Presentation API v3 for the presentation layer and the IIIF Auth protocol for the integration with Avalon. We will show the tool and also discuss the technical aspects of the IIIF standards. | Developers, Repository or DAMS Managers, Administrators |
| 12:12- 12:19 PM EDT | Hyrax Batch Ingest: A gem in use Sadie Roosa (WGBH) | A quick look at how WGBH is using the hyrax-batch_ingest gem in their AMS app for multiple shapes and sizes of ingest. | Developers, Repository or DAMS Managers, Metadata Specialists |
| 12:20- 12:27 PM EDT | An approach to File CRUD and attachment APIs Sean Upton (University of Utah J. Willard Marriott Library) | Attaching files in Hyrax for purposes of ingest and other programmatic use is complicated. This talk describes some challenges around file attachment, generally, and presents a wrapper API with simpler calling semantics both for access and attachment of primary and derivative files (and abstraction of associated operations usually buried in the actor stack or asynchronous jobs). The adapter components providing this simple interface provide a uniform and succinct way for multiple ingests to have consistent behavior. This brief talk will present the proposed "assign and commit" calling semantics around file attachment, and make the case as to why this approach is the best fit for how Hyrax and associated stack components implement file attachment process. These components have been developed as part of the IMLS-funded Historic Newspapers in Samvera project. | Developers, DevOps and System Administrators, Repository or DAMS Managers, Anyone building ingest processes |
| 12:28- 12:35 PM EDT | Amazon ElasticTranscoder in Hyrax Phuong Dinh (Indiana University) | We are going to show how to ingest audio and video files using Amazon ElasticTranscoder with Hyrax through active_encode. | Developers, DevOps and System Administrators |
12:36- 12:43 PM EDT | Implementing Custom Theme Solutions in Hyku Lea Ann Bradford (Notch8) | Notch8 recently implemented custom theming for the PALNI/PALCI joint Hyku project. This talk will go over how we installed access to Google fonts as well as a code editor gem to enable each tenant in the project to write its own CSS. This allowed for much expanded customization and theming experience. | Developers |
| 12:44- 12:51 PM EDT | Implementing an Alternative Rails-based Digital Collections Architecture Jonathan Rochkind (Science History Institute) | At the Science History Institute (formerly Chemical Heritage Foundation) we are working on re-implementing our digital collections application using a new Rails-based architecture, including sharing some building blocks in a ruby gem for those who may be interested in the same directions. Our code is not based on hyrax or valkyrie; our persistence layer is based on postgres, ActiveRecord and metadata serialized in a JSON column. The sharable gem code already includes support for flexible derivatives; file handling using shrine; and some HTML form support for complex/repeatable fields. It will in the future include some solr indexing support. These components are designed for flexibility and support of performant DB usage patterns. This talk will provide a fast-paced tour of our architecture by showing example code. | Developers, DevOps and System Administrators, decision-makers for technical architecture/platform choices |

| 1:30- 1:59 PM EDT | New Directions for Northwestern: Taking a Cloud-First Approach Michael B. Klein (Northwestern University) Adam Arling (Northwestern University) Karen Shaw (Northwestern University) Brendan Quinn (Northwestern University) David Schober (Northwestern University) | Northwestern University Libraries is currently running Samvera applications in production. Three of these are developed, maintained, and managed by the Repository & Digital Curation workgroup:
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:
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. | Developers, DevOps and System Administrators, Repository or DAMS Managers |

| 2:00-2:29 PM EDT | U-M Digital Collections by the Numbers John Weise (University of Michigan) | 6,761,224,773 words. 2,823,957 images. 200+ content sources. And a very long tail of unique metadata fields. This will be a "by the numbers" tour of the digital collections at the University of Michigan Library that highlights some of the challenges of designing and building a new repository and access system for our digital collections that can handle scale, variety, growth, and a rich feature set. | Developers, Repository or DAMS Managers |
