Autoload: a pipeline for expanding the holdings of an Institutional Repository enabled by ResourceSync

Providing local access to locally produced content is a primary goal of the Institutional Repository (IR). Guidelines, requirements, and workflows are among the ways in which institutions attempt to ensure this content is deposited and preserved, but some content is always missed. At Los Alamos National Laboratory, the library implemented a service called LANL Research Online (LARO), to provide public access to a collection of publicly shareable LANL researcher publications authored between

LARO exposed the fact that we have full text for only about 10% of eligible publications for this time period, despite a review and release requirement that ought to have resulted in a much higher deposition rate. This discovery motivated a new effort to discover and add more full text content to LARO. Autoload attempts to locate and harvest items that were not deposited locally, but for which archivable copies exist. Here we describe the Autoload pipeline prototype and how it aggregates and utilizes Web services including Crossref, SHERPA/RoMEO, and oaDOI as it attempts to retrieve archivable copies of resources. Autoload employs a bootstrapping mechanism based on the ResourceSync standard, a NISO standard for data replication and synchronization. We implemented support for ResourceSync atop the LARO Solr index, which exposes metadata contained in the local IR. This allowed us to utilize ResourceSync without modifying our IR. We close with a brief discussion of other uses we envision for our ResourceSync-Solr implementation, and describe how a new effort called Signposting can replace cumbersome screen scraping with a robust autodiscovery path to content which leverages the Web protocol.
