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

however, library enduring commitments in print and current operations, and complex campus organizations often hinder libraries¹ ability to quickly respond to the data needs of the academy. Notre Dame¹s investment in research was recently reinforced by the university¹s approval of the expansion of ten disciplines, such as computational data, adult stem cell research, and nuclear physics. There is much needed support for research data on campus. The Hesburgh Libraries has been building an institutional digital repository since winter 2012. To respond to the trending needs, the Libraries switched gears to a user-centered and agile approach to develop data curation and access services since June 2013. Our goal remains to accept all scholarly outputs (text, images, video and audio), but with an imminent emphasis on research support. Our strategy is to grow our data curation services and our user base simultaneously, and to build success stories to drive adoptions along the way. Early adopters were identified with the help of our subject librarians, and they determined the most critical baseline features for the Libraries to develop. We also leveraged Hydra open source solutions and collaborated with Northwestern University, Indiana University, and the University of Virginia to create a new community shared Institutional Repository (IR) system. We have worked with our early adopters to pilot features since summer. We plan to launch an early access release by November 2013 and a full rollout by April 2014. We will share our development philosophy to overcome resource shortages to meet high demands on research support, our strategy to reach and develop our user base and roadmap, our insights on faculty¹s needs on research support, and our methodology to leverage and contribute to open source tools. A quick demo of our curation tool will be provided at the end of the session. and A presentation to the CNI Members' Meeting in December 2013. This session provides Notre Dame¹s experience as a case study to provision research data curation and access services. Managing research outputs becomes a tall order of many universities, given their determined agenda to pursue research excellence. In a world of increasingly data-intensive research, data is rising as a critical component of scholarly communication, often mandated by granting agencies. Data curation, preservation, and access are paramount to university academic mission, and academic and research libraries are some of the few entities of the universities that carry such functions
