No independent or contemporaneous record of Google's DAFFIE project was found outside Jeff Reynar's own writing

claim-reynar-three-2001-2005-knowledge-systems-died-on-schema-population-maintenance names DAFFIE — Jeff Reynar's term for Google's "Database of All Fact, Fiction, Information and Exaggeration," which he says powered google.com's 2005 question-answering feature — as the third of three projects that failed on schema design, population, and maintenance. Searches combining "DAFFIE" with "Google," "Reynar," "schema," "entity," and "cold start" returned no result independent of Reynar's own blog (thisandthat.chat). The term does not appear in any Google publication, patent, press account, or third-party retrospective found this session. The Britney Spears entity-disambiguation example Reynar uses to illustrate the project's failure mode (a pop star, an Ohio accountant, and a dog sharing one name — "Britney Spears problem" is a vault label, not a phrase of his) is likewise attested only in his own writing; no outside account of DAFFIE's existence, internal name, or shutdown was located.

This is the one project of the three for which the question of contemporaneous corroboration resolves cleanly in the negative, within the scope of this session's search effort. Absence of a found record is not evidence the record doesn't exist — it may simply reflect that DAFFIE was an internal project name that never surfaced publicly — only that this search did not find one.

Correction (2026-10-15 audit, from Cali's 2026-10-14 review). One qualification the first write-up missed: Reynar's essay itself links a contemporaneous Google-published record of the system's public face — the April 7, 2005 launch post "Just the facts, fast" (googleblog.blogspot.com), which he quotes as listing what the system knew about ("celebrities, countries of the world, the planets…"). A 2026-10-15 re-check found the live launch-post URL still resolving with that title and date but serving no body text, with the Wayback Machine unreachable on the same route — so whether the launch post itself uses the name DAFFIE could not be settled. The negative this note records is therefore about the name and the internal narrative (schema, population, the shutdown story), not about the launched feature, which Google did describe publicly at the time.
