In this article we discuss ongoing work on documenting text-reuse in the Deipnosophistae of Athenaeus of Naucratis. We present a data model for identifying uniquely instances of text-reuse that are as specific or non-specific as necessary, that can cover types of reuse from direct quotation, through paraphrase, to allusion, including instances where the reused text is non-contiguous. We illustrate our discussion with examples from our work, starting with six cases of reuses of Homer's Iliad in the Deipnosophistae. Our data model is developed on the Canonical Text Services (CTS), which is a protocol for identifying and retrieving passages of text based on concise, machine-actionable canonical citation. The data model consists of six fields, and we argue that each of these six is necessary, and that together they are sufficient.
