Title: IPARO: InterPlanetary Archival Record Object for Decentralized Web Archiving and Replay
Author(s): Sawood Alam
Abstract: We proposed a decentralized version tracking system using the existing primitives of IPFS and IPNS. While our description talks primarily about archived web pages, we proposed the concept of IPMT and namespacing so that it can be used in other applications that require versioning, such as a wiki or a collaborative code tracking system. Our proposed system does not rely on any centralized server for archiving or replay of the content. The system continues to allow aggregators to play their role from which both large and small archives can benefit and flourish.

Title: Tacit Processes: Qualitative Analysis Toward Bottom-Up Emulation Workflows
Author(s): Eric Kaltman and Adam Larson
Abstract: This paper describes the use of a modification of qualitative grounded theory to analyze in-situ preservation workflows making use of emulation techniques. The goal of this in-process work is to identify and delineate common tasks across the emulation of different classes of software objects through a unique approach based in bottom-up qualitative observation.

Title: A Storage and Search Demonstration with DNA-Encoded Text
Author(s): Laurel Provencher, Swapnil Bhatia and Sean Mihm
Abstract: DNA-based data storage (DDS) holds promise to deliver a paradigm shift for long-term, secure storage of data. To tap into this potential, methods must be developed to produce data-encoding DNA molecules with cost- and time-effective processes. Combinatorial synthesis of DNA molecules from pre-fabricated fragments of DNA offers a solution to this challenge. We are developing a DNA-based platform combining encoding algorithms, high-throughput synthesis, post-synthesis processing, sequencing, decoding algorithms, and computation architectures into a unified system. DNA datasets encoding images and literary works have been successfully created and translated back into conventional data files containing the entire original set of data or a targeted subset of data. In this work, we demonstrate the ability to search for specific molecules encoding a specific word in a DNA dataset encoding the complete text of multiple literary works.

Title: Quality Preservation: Emerging Quality Assurance Practices in the Library of Congress Web Archives
Author(s): Meghan Lyon and Grace Bicho
Abstract: Building sustainable quality assurance practices is a challenge for today’s preservationists, who want to be sure that content preserved in web archives is not only the correct content, but in working order. This often means that archived web content should be replayed via Wayback rendering software in good fidelity when compared to the original website. The exponentially growing scale of web archives necessitates a multipronged approach to identify what is (and is not) being preserved, and where improvements can be made. This paper will explore actions that can take place iteratively throughout the web archiving life cycle, as part of a larger system of review where multiple individuals can contribute, including non-technical Library staff and subject matter experts. The processes described are part of a novel workflow in the Library of Congress Web Archiving Program.
