<p>Aimed at the TEI editing community and intended to be run inside oXygen, the Data Dictionary Generator (DDG) generates profiles of every element and attribute appearing in a TEI file. Each entry includes a definition from the TEI Guidelines, a local, project-specific definition (if provided), and a brief snapshot of how the element or attribute is actually being used. By making it easy to compare these three things, the DDG aims to help project editors reflect on current practice within their projects and quickly create stronger encoding guidelines for their collaborators.</p>
