"The University of Tennessee Digital Library Center has released the UT-DLC MODS Metadata Workbook to the library community. Developed by Cricket Deane under the direction of Melanie Feltner-Reichert, this open source client-side software provides control of date formats and other problematic fields at the point of creation, while shielding creators from the need to work in XML. The tool consists of a series of web pages that enable users to easily generate complex, valid MODS metadata records that meet the 1-4 levels of specification outlined in the Digital Library Federation Implementation Guidelines for Shareable MODS Records, (DLF Aquifer Guidelines November 2006)."
