A system for encoding bird field notes

How should a large collection of bird notes be organized into files? The author feels that a month's worth of notes is a reasonable size for one file. Files are named as yyyy-mm.xml, where yyyy is the year and mm is the month number. The overall organization places a year's worth of notes in one directory whose name is the year number. So, from the root directory, file 2004/2004-09.xml contains the notes for September 2004.

So to begin our discussion of the schema, we assume that each document represents all the notes for one calendar month.
