24x7: Digital Preservation of the NLM Digital Collections

Doron Shalvi1,2, John Doyle1, John Rees1, Ben Petersen1, Felix Kong1

1U.S. National Library of Medicine; 2CSC, United States of America

This presentation will cover the topic of digital preservation with respect to the National Library of Medicine (NLM) Digital Repository. The presentation will describe our overall preservation goals and requirements, the aspects of preservation satisfied by our current system, and where we plan to enhance our system in the future to further meet these preservation goals. We will describe the architecture of our system and the detail of components that provide preservation services, and how they are implemented. Specific topics to be reviewed include the current and potential implementation of services for identification, fixity, auditing, replication, and interface to other systems. We will relate these services to our current Fedora 3-based system and how these functions could be implemented in a Fedora 4-based system. The presentation should serve as a useful example to other organizations with systems of similar size and complexity that are looking to implement preservation services within their systems.

24x7: Learning to use Fedora 4 as a BIBFRAME Linked Data Platform

Jeremy Nelson

Colorado College, United States of America

As the primary developer of a BIBFRAME Catalog for the Library of Congress; Jeremy Nelson uses Fedora 4 as the critical core Linked Data Platform for storing and managing subject RDF graphs of BIBFRAME Linked Data. With BIBFRAME Catalog's user interface created by Aaron Schmidt of Influx Library Experience Design, a flexible approach for was needed not only for this project, but for other work being done by Jeremy Nelson for Colorado College. This requirement for a supporting multiple user and institutional demands, follows a "pull platform" approach that lead to the creation of an open-source integration architecture project simply called a Semantic Server. The Semantic Server provides a REST API to Fedora 4, Elastic Search and Fuseki that allows for CRUD management of RDF resources supporting BIBFRAME, MARC21, Schema.org, and other vocabularies as needed different user communities - including staff and administration - of library and cultural heritage organizations.

This talk will demonstrate and explore how as Fedora 4 has matured towards production, the strategies and approaches for providing searching and displaying of BIBFRAME RDF graphs using Elastic Search and Fuseki has changed while other uses are being actively developed as a semantic server.

Making the SHiFt: Using Sufia with Hydra/Fedora for collection management and access

James Halliday, Juliet L. Hardesty

Indiana University, United States of America

Indiana University Bloomington Libraries is involved in two new projects to digitize and store content and related metadata. Each of these projects presents unique challenges. We want to use the same technology stack for both, however, so we are choosing Fedora as a storage mechanism, with Hydra-based Sufia as a repository front end. We will discuss our decision, show advantages of this Hydra/Fedora framework, and discuss advantages of moving to Fedora 4. We will also contrast this framework with the way we might have approached these projects in the past with previous versions of Fedora and before Sufia or Hydra were options.

Avalon at the Crossroads: Metadata Strategies for Time-based Media Blues

Juliet L. Hardesty

Indiana University Libraries, United States of America

Avalon Media System requires support for complex structure and modular descriptive metadata management. Use cases and examples will examine options for Avalon in Fedora such as the RDF data model in Fedora 4, static XML datastreams, and external data stores to determine which path best fits structural and descriptive metadata needs for time-based media.
