This chapter describes the digital infrastructure for the collaborative project. The Multitext Project explicitly aims to design an infrastructure for the study of the Iliad that can outlive specific software applications and survive beyond the careers of individual scholars. Texts make up one category. Each text is encoded as an Extensible Markup Language (XMl) document complying with version P5 of the Text Encoding Initiative (TEI) Guidelines. In the homer Multitext, every text is instead organized by its citation hierarchy, which can be addressed by canonical Text services uniform Resource Names (or CTS URNs). An overlapping analytical structure, such as speeches in the Iliad, can be represented by simple tabular objects. With a full suite of CITE (collections, indexes, texts and extensions) implementations in hand, authors have recently begun to focus more of our attention on applications founded on material in the Homer Multitext supplied by CITE services.
