ResourceSync at UCLA: PRL Use Case
Pacific Rim Library provides access to aggregated metadata records from the Pacific Rim Research Library Alliance (PRRLA), an organization of academic libraries surrounding the Pacific. With grant funds from PRRLA, the UCLA Library has completed the first phase of the ‘next generation’ PRL with a redesigned interface and an upgrade to ResourceSync. We have developed and contributed to open source software that enables institutions to deploy ResourceSync capabilities that plug into their existing OAI-PMH repository. The presentation will provide an overview of the project and a forum for discussing opportunities for ResourceSync development and implementation at UC.

IIIF Tiling on Demand with AWS Lambda
Some digital library image projects require a full-fledged IIIF image server that can generate images of varying dimensions on demand. Others just need to provide an interactive image zooming functionality. For the latter types of projects, it's sufficient to pre-generate image tiles to be served from a IIIF "Level 0" tile server (which might be a IIIF-specific tile server or just a generic Web server like Apache or Nginx). This approach saves disk space, simplifies the system architecture, and may not require an additional caching layer to make the serving of tiles performant. At UCLA, we've written a IIIF tiling server that pre-generates the tiles for IIIF viewers like OpenSeadragon, Mirador, and the UniversalViewer. We started using it by running the tiling process on AWS EC2 instances; that gave us processing power on demand without the need to provision and maintain a local server. That approach worked well, but in time we realized we could simplify the process even further by extracting the tiling functionality onto AWS Lambda. We propose to talk about our experiences doing this and why we think Lambda is a good fit for IIIF tile generation.

Building & Managing a Large Collaborative Open GIS Project
Libraries are increasingly involved in providing data management and GIS services, consultations, project collaboration, and creating open digital data collections. In this talk, Michele and Tom discuss the American Viticulture Areas (AVA) Project and address how the tools and workflows used to create and manage this dataset can be repurposed for other data collections with multiple contributors with limited infrastructure and funding. The AVA Project began as a collaboration between UC Davis and UCSB to create digital spatial data for all 239 boundaries of the American Viticulture Areas as described in the US ATPF Code of Regulations in support of key research conducted at our institutions. The AVA Project utilizes user-contribution practices in the GIS community that have successfully generated open-licensed global datasets like Open Street Map combined with US government documents, open data formats (geoJSON), open source GIS software (QGIS), and collaboration tools (GitHub) to provide a high-quality open and accessible research resource. The project provides the dataset free of charge through a system that accepts contributions, corrections, and updates. The methods employed in the AVA Project provide a framework for managing other collaborative data creation projects, including contributions from multiple campuses as well as entities outside the UC.
