Hi Ryan,
We have another web API called Exhibit that provides filtering, and
sorting, on Timeline as well as Google Maps and other views:
http://simile.mit.edu/exhibit/
Does that address your need?
-----
However, if you want to stick to Timeline, Timeline does provide a more
primitive mechanism for filtering and highlighting. For instance, in
this example
http://simile.mit.edu/timeline/examples/jfk/jfk.html
you can filter and highlight events containing whichever text you type
into those text boxes at the bottom. Take a look at the HTML code and
find that it includes another Javascript file:
http://simile.mit.edu/timeline/examples/examples.js
In that file, filterMatcher and highlightMatcher are what you want to
modify to suit your need. Right now they work on the "text" and
"description" properties of each event, but you can have them work on
any other property you want. evt.getProperty(propertyName) will retrieve
the corresponding attribute from the XML element. For example, if you
encode your event in the XML file as follows
<event title="Christmas" start="December 25 2006"
category="holiday">Christmas Day</event>
then evt.getProperty("category") will return "holiday".
Cheers,
David
