HOLIE (short for Holographic On-Line Interactive Encyclopedia) was an experimental hologram installed aboard the USS Cantabrian as a part of her refit at Utopia Planitia Fleet Yards in 2372. Captain Noah Wrightson described HOLIE as, "the embodiment of the ship's computer with a personality template". (He also added he had not been very impressed with initial displays of the HOLIE system to him.) HOLIE was replaced, in 2374, by a Kaartali hologram named HEIDI, aboard the USS Cantabrian-A. Unlike HOLIE, HEIDI did not not have any constraints on where she could go within the ship.
