In this presentation you’ll learn about the tools, strategies, and decision-making currently being used in migrating 20 years of metadata and digitized special collections from BYU’s CONTENTdm system to a new, highly customizable OrangeDAM platform. This migration involves transforming and standardizing our often inconsistently entered metadata from years’ past to align with a newly developed digital collections MAP based on Dublin Core fields and RDA guidelines, with corresponding fields in MARC and ArchivesSpace included. This work is also being done in collaboration with our BYU sister schools, BYU-Idaho and BYU-Hawaii, which also host digitized materials in the BYU Library’s digital asset management systems. This presentation will cover the practical challenges of metadata cleanup, transformation, and migration, and MAP creation, offering insights into our process, tools used, and lessons learned so far to improve findability and usability across our digital collections.
