Description: Poster illustrating issues involved in fully-implementing the Extended Date/Time Format (EDTF) standards in the UNT Libraries' digital collections, comprising The Portal to Texas History, the UNT Digital Library, and The Gateway to Oklahoma History. The first section, "Analysis of Dates," provides statistics related to the number of valid entries among existing date instances in the system, the most common issues with non-EDTF valid dates, and the number of valid dates after simulating automated conversions for adjusting some non-valid dates. The second section illustrates the written guidelines provided for metadata creators and the embedded validation tools that alert persons entering metadata when the dates do not meet EDTF standards. The third section includes screenshots to show date normalization in the user interface, to make formatted dates more accessible, and the icon that is used when dates cannot be easily normalized, providing access to a glossary.
