2. Making TACOs for Hydras
- Description:
- 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

6. "Headless" Metadata for Library Discovery: NYU's Ichabod Project
- Description:
- A presentation given at the Open Repositories conference in 2015 held in Indianapolis, described thus, Fedora, Hydra, Solr, and Blacklight. Called “Ichabod,” this tool has allowed us to ingest, normalize, and enrich metadata from diverse systems of record and make it consumable by our main discovery tool, which is powered by the Ex-Libris product Primo. We developed Ichabod using the Agile methodology and involving developers from three distinct NYU Libraries groups. The software will lay the groundwork for future innovation in the areas of metadata management and discovery for repository content. The relationships we established have already made it possible for a similar collaboration arrangement on two other projects, with more to come in the future., and From DSpace to Drupal, NYU has a variety of systems to ingest and display curated digital content. To make this content discoverable centrally, we developed a tool for metadata ingest, transformation, and discovery based on a popular open-source software stack

8. Avalon Media System: Community Implementation and Sustainability
- Description:
- Indiana University and Northwestern University, in collaboration with nine partner institutions, recently completed the last year of a three-year IMLS-funded effort to build the Avalon Media System, an open source solution for managing and providing access to digital audio and video collections, based on Fedora and the Hydra repository software development framework. As the Avalon platform reaches maturity, several institutions are in the process of implementing Avalon both to replace current time-based media access solutions and to support new use cases. In addition, new funding from the Andrew W. Mellon Foundation will support continued work to develop new features, grow and provide support for the community of adopters, and move Avalon towards organizational and financial sustainability. This panel will bring together project leaders from Indiana and Northwestern, along with Avalon community members at the University of Virginia and Stanford University, to share experiences of implementing Avalon at their institutions, integrating Avalon with other local systems, and supporting Avalon to enable a variety of use cases in research, teaching, and learning. Panel members will also discuss future development plans and provide a preview of how the project intends to transition from a grant-supported endeavor to a community-sustained solution. and Slides for a panel presentation given at the Open Repositories conference in 2015 held in Indianapolis described thus

10. Case Study: Batch update : What we talk about when we talk about design thinking
- Description:
- 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

11. Building a GLAM ecosystem: Human and machine collaborations for digitized collections
- Description:
- one size would not fit all for our campus archives, library, and museum, and community needs above all. In this presentation, team members will talk about the past two years of experimentation, development, and conversation around how to connect our community to our cultural heritage collections through multiple integrations, both human and technological. At a high-level, we’ll discuss our technical architecture that uses legacy applications like ArchivesSpace, an aging Fedora repository, and a decades-old museum database together with the IIIF framework and open-source GatsbyJS. And perhaps more importantly, we’ll outline the cross-departmental team structure that has developers talking to museum curators, library cataloguers, archivists, and everyone in between.

12. Shifting Gears
- Description:
- A presentation given at Samvera Connect 2020 On-line described thus and Princeton University Library’s digital projects and initiatives were seriously disrupted by COVID-19. Digitization of materials for projects and forthcoming exhibitions came to an unexpected halt at the same time as patrons and staff were separated from physical objects and library spaces. Necessity, however, provided an opportunity to reassess digital projects and how staff members interact with and contribute to our repository (Figgy). We focused on the creation of workflows and documentation for new contributors who would be working in the repository, helping them enhance existing digital objects with OCR, item level organization, structural metadata, page labeling, and IIIF display attributes. We describe how we were able to use Figgy and unexpectedly-available staff time to make more effective research tools and provide a better user experience for patrons and staff working with our digital collections. Such enhancements add immense value to our collections as well as to our applications, and the work can be done effectively by a wide range of staff from different departments with variable skill sets.

14. Supporting collaboration in Hyku: Workflows, tools, and design
- Description:
- A presentation given at Samvera Connect 2020 On-line described thus and Collaboration is more than just sharing costs, and the PALCI and PALNI consortia are pushing that idea into our repository management. We want to create the flexibility for both IR workflows and more “traditional” library-owned content within the same instance of Hyku. We also want to enable libraries to collaborate and share work, not just with their consortial partners, but also among their own departments across campus. To us, this means enhancing the ability to manage user and tenant settings to enable different workflows. By working with a number of libraries testing out the Hyku multi-tenant option, we realized that a robust dashboard for user/role assignment and the expansion of a few more roles would enable us to manage these flexible workflow options. PALNI and PALCI are working with Notch 8 to enhance the underlying “role” and “group” functionality in Hyku and develop a new administrative dashboard to control permissions across multiple tenants. We will also be expanding role and group functions within tenant management. This presentation will discuss how we researched and developed our requirements as well as the plan and progress to date.

- Description:
- In the UK, the Universities of York and Hull are looking at Archivematica's place in a research data pipeline. The two universities have slightly different use cases but share the desire to put research (and likely other) content through Archivematica on its way to the repository thus giving us a solid base for long-term preservation. We are both now in the third phase of a joint project to build proof-of-concepts to illustrate how Hydra and Archivematica can work together to manage and preserve research data. Since our project began, Jisc have launched an ambitious UK national research data shared service where a range of suppliers offer systems in different lots. Both Hydra / Fedora and Islandora / Fedora are part of the the ‘research repository’ lot of the service and the work of York and Hull has heavily informed the ‘preservation’ lot, with Archivematica one of the systems on offer. This presentation will describe the proof-of-concept work done by Hull and York, and will provide an overview of the new Jisc service.

20. Hydra for Cultural Heritage and Beyond the Institutional Repository
- Description:
- Using Hydra to manage and present cultural heritage resources raises a set of interesting challenges that are beyond the scope of the traditional institutional repository. These include more complex data models, elaborate and varied workflows, richer descriptive metadata, support for more and varied controlled vocabularies, the requirement to manage larger objects comprised of larger files and multiple derivatives, support for IIIF, and a desire for richer viewing environments in general. In this presentation we will discuss these challenges and highlight examples and implementations that have gone ‘beyond the repository’.
