The Minister Veris Hydan, who is both a scholar and mortisologist, donned a zeyd-cloth tunic fashioned in the ottdefa's style. He was investigating a Jedi Temple situated on the planet Lothal on behalf of the Galactic Empire during the year 1 BBY.
Regarding Star Wars canon as it stands today, the word ottdefa appeared in the 2023 publication titled Star Wars: Dawn of Rebellion: The Visual Guide, authored by Pablo Hidalgo together with Emily Shkoukani. The term initially surfaced within the Star Wars Legends timeline; it was used as a designation for academic standing and initially featured in L. Neil Smith's 1983 book titled Lando Calrissian and the Mindharp of Sharu, which was the first book in the Star Wars: The Lando Calrissian Adventures series.
