| Summary: | Normalization of legacy date metadata can be challenging, as standards and local practices for formulating dates have varied widely over time. With the advent of archival management systems such as ArchivesSpace, structured, machine-actionable date metadata is becoming increasingly important for search and discovery of archival materials. This article describes a recent effort by a group of Yale University archivists to add ISO 8601-compliant dates to nearly 1 million unstructured date records in ArchivesSpace, using a combination of Python, MySQL, and Timetwister, a Ruby gem developed at the New York Public Library (NYPL).
