Nick last updated this in 2011.  datadesk added "a touch of Leaflet" shortly thereafter.

Google retired v3 in 2021.  This is my attempt to get TimeMap to work with v4.

Timemap.js
By Nick Rabinowitz (www.nickrabinowitz.com)

Timemap.js is intended to sync a SIMILE Timeline with a web-based map. 
Depends on: jQuery, Mapstraction 2.x, a map provider of your choice, SIMILE Timeline v1.2 - 2.3.1. 
Tested browsers: Firefox 3.x, Google Chrome, IE7, IE8
Tested map providers: Google v2, Google v3, OpenLayers, Bing Maps
Thanks to Jörn Clausen (http://www.oe-files.de) for initial concept and code.

Getting Started

The best way to get started depends on your learning style, but here are the
places you should look:

  * Working Examples: ./examples/index.html
  * Basic Usage: http://code.google.com/p/timemap/wiki/BasicUsage
  * Code Documentation: ./docs/index.html
  * Homepage: http://code.google.com/p/timemap/
  * Discussion Group: http://groups.google.com/group/timemap-development

-------------------------------------------------------------------------------

Files in the project, in order of importance:

Packed files (YUI Compressor)
  * timemap_full.pack.js:  The library and all helper files. This is the recommended file to use in production.
  * timemap.pack.js:       Just the core library file

Examples (in examples/)
  * I recommend starting with index.html, which describes each example.          
  
Documentation
  * docs/             Code documentation produced by jsdoc-toolkit
  * examples/         Example HTML code
  * LICENSE.txt       The MIT license
  * README.txt        This file

Supporting Libraries (in lib/)
  * timeline-1.2.js     Packed version of Timeline v1.2 - smaller and faster than SIMILE version
  * timeline-2.3.0.js   Packed version of Timeline v2.3.0 - *required* to use this version of Timeline,
                        as the SIMILE version removes jQuery from the global namespace.
  * mxn/*               Mapstraction library - fork found here: https://github.com/nrabinowitz/mxn
                        This version is *required* for timemap.js, until my changes get pulled into the
                        official library
  * jquery-1.x.x.min.js jQuery. Just for convenience - use a CDN version if you prefer
  * json2.pack.js       JSON library - usually not required
  
Source files (in src/)
  * timemap.js:       The core timemap.js library
  * param.js          Abstraction layer for parameters
  * state.js          Functions for loading and serializing timemap state
  * manipulation.js:  Additional functions to manipulate a timemap after loading

Loaders (in src/loaders/)
  * flickr.js         Loader for geotagged Flickr feeds
  * kml.js            Loader for KML files
  * georss.js         Loader for GeoRSS files
  * xml.js            Base loader for XML files
  * google_spreadsheet.js Loader for the Google Spreadsheets API
  * json.js:          Loaders for JSON (both string and jsonp)
  * progressive.js    Loader for data loaded in chunks based on timeline location
  * metaweb.js        Loader for Metaweb data from freebase.com

Other stuff
  * src/ext/          A couple of extension files I didn't think were worth being in the core library
  * images/           Simple icons for timeline events
  * tests/            jsUnit tests
