While identifiers like AGES-SP-01-002 are invaluable, their use also presents challenges. Ensuring consistency, avoiding duplication, and maintaining accessibility are critical considerations. Databases and catalogs housing these identifiers must be robust, user-friendly, and well-maintained to maximize their utility. This work is considered a foundational text in
