Subject: Baseline representation
Date: 15 Kislev 5780
Following our discussions at Thursday's session on date representation, I believe we must now address the baseline question before proceeding with indicator encoding.
An observation occurs at a moment. But moments are not self-identifying. If I record "three stars visible," how does a reader know which evening I mean?
I would note the following:
1. A date provides the day, but not the moment within the day. 2. Even the date requires knowing when one day ends and the next begins. 3. This is precisely what the observation is meant to establish.
The committee has faced similar questions before. The circular definitions in the date specification gave us trouble for months. I do not have a proposal here. I raise the question so that we may address it systematically.
