The Iowa Canon of Ancient Authors and Works, currently under development, will be based on a database of all known Greek and Latin authors and their writings, including fragmentary and lost texts, from the earliest period through the seventh century CE.  It will provide extensive metadata for each work, including the date and place of its composition; its status as pseudepigraphic or disputed; its status as complete, fragmentary, or lost; its status as a translation or original Latin composition; its status as Christian or non-Christian; attested abbreviations for the work; a genre designation based on the project’s genre typology; and cross references to other canonical ids (such as the Perseus Catalog, digilibLT, and the Packard Latin Canon).  The Canon’s metadata will be available through multi-faceted search and browse in a map-centered interface which visualizes user-selected works according to the location of their author.  A beta version, to be released in Fall 2019, will focus on the Latin Canon.  The subsequent phase of the project, in 2020, will be the integration of the Latin Canon with the Greek Canon through their shared metadata categories.
