I starting a couple of projects where I hope to use TimeLine and
TimePlot.  Our goal is to have users contribute to the database
through an online interface.  One thought was to create a webform that
allows users to enter data into a database (MySQL) then write a script
(probably PHP or Python) that queries the database and returns XML or
JSON data (not sure which is best) to the eventsource of the time*
object.

For single events, this should be easy since all you need to capture
is date/range, title, and description.  For time series data, it would
take more work since a dataset (csv, xls, tab files) would need to
uploaded and parsed before going into the database.   In any case,
we'd need to work with authentication, editing submitted data, quality
assurance, and similar issues.

Has anyone done this before?  Are there any obvious pitfalls (database
schema, performance lag) that are known?  Does this approach make
sense?   Thanks for any help you can provide.
