Hello Hacker News! This is more of an experiment/statements I wanted to make about needing specs for things (e.g. for agents to output) more than an actual "spec for itineraries."
While schema.org exists, it is a massive specification with a lot of cases that are likely unused if you were to optimize it for application use. This project really just points at the tension between using such an extensive schema versus more "practical" and application-focused ones, especially when token costs are in the question.
