Overview
--------------

Each morning, tables summarizing published locations, names, and places are written to 
gzipped CSV files at http://atlantides.org/downloads/pleiades/dumps/. We keep a week's 
worth of files, deleting older ones. The schemas of these files are documented in a README. 
The resources under http://pleiades.stoa.org/places/ remain the canonical ancient world 
resources; the contents of the tables are only thin slices. The recently-modified page 
(http://pleiades.stoa.org/news/recently-modified) or its corresponding RSS feed 
(http://pleiades.stoa.org/news/recently-modified/RSS) are the best ways to track what is 
changing in these daily dumps.

Locations, names, and places are written each morning to separate tables in CSV
format. The first row of each file contains column names. All files are UTF-8
encocded. The "pid" column of locations and names tables can be joined to the
"id" column of a places table.
