The current system is meant to serve BOTH purposes...
1) An up-to-date, easy to use, toy-rich calendar for today
2) An intricate, detail heavy archive for the future.
All reviews, publications, show details, cast/company lists, etc, etc stay on the calendar forever...or as long as electricity keeps pumping. The dates currently go back to August 2003, and events may be added as far back as January 2000. I can set the system to add dates even before that if any person or theatre cares to archive that far back. Eventually, cast lists will integrate with the TPS individual member records to create an IMDB-like listing for the events.
Already, the TPS organization DB is connected to the system. For instance, if you go to http://seattleperforms.com
and click 'theatres' (left hand menu) you will see a complete list of the current producing members of TPS. It's pretty extensive too! Click on a theatre, see details about them including ANY current or upcoming events listed on SeattlePerforms. There is also a link to view EVERY event that is connected to that organization.
