Metadata Migrations: Managing Methods and Mayhem

Are you preparing to migrate out of a legacy system?  Do you have questions about metadata remediation, repurposing, or enhancement?  Of course, you do and we are here to help.  During ALA Annual in Chicago, The ALCTS Metadata Interest Group will be sponsoring Metadata Migrations: Managing Methods and Mayhem on Sunday June 25th from 3-4 pm in Room W185bc.  During this time, come hear experiences from the front lines with presentations from Maggie Dickson-Metadata Architect from Duke University Libraries; and Gretchen Gueguen-Data Services Coordinator from DPLA.  Looking forward in seeing you all in Chicago.  Do not forget to add this event to your ALA Conference Scheduler.

Title: Looking Back, Moving Forward: Remediating 20+ Years of Digital Collections Metadata

Presenter: Maggie Dickson, Metadata Architect, Duke University Libraries

Abstract: In 2015, DUL began the process of migrating its digital collections to the Duke Digital Repository, a Fedora/Hydra/Blacklight-based platform. In preparation for this migration, we undertook a large-scale analysis and remediation of metadata describing approximately 112,000 items, created over the course of twenty years, by many different people, and using many different schemas and standards (or not). We formed a task group to make decisions, identify and engage stakeholders, and guide the workflow. This involved reviewing existing properties and values and evaluating the adoption of standards and vocabularies, with an eye toward linked open data and sharing our resources with the DPLA and beyond. The remediation itself (which at the time of this proposal is ongoing) is being completed using OpenRefine, scripting, and many good old spreadsheets. This presentation will describe the process, its challenges and successes, and future directions.

Title: The Never-Ending Migration

Presenter: Gretchen Gueguen, Data Services Coordinator, Digital Public Library of America

Abstract: What if all you did was migrate metadata from one system to another? In a sense, that is what metadata mapping at DPLA is like. The first 2.5 million records were harvested and mapped in 2013 from 500 initial partners. Since then DPLA’s collection has grown to nearly 15 million records from more than 2000 contributing institutions. Since the project relies on metadata harvesting and synchronization, metadata is continually being harvested and mapped. This presentation will explore the tools and techniques that DPLA uses to analyze and map metadata from a variety of standard and bespoke metadata formats into a normalized application profile. Recently DPLA has been developing a new open source tool that can be used by anyone to harvest and map and analyze metadata from common data sources such as OAI feeds. Work on the creation of these tools as well as data quality efforts at DPLA will be reviewed.
