Google Maps Mashups with Google Mapplets

Chapter 4: Creating Geocoded Data Feeds

In the previous chapter, you learned how to geocode Tourfilter's concert data. At this point in your mashup, you know the location of each concert in Tourfilter's feed. The next step in your mashup is to create a feed of the geocoded data and expose the data to your Google Mapplet.

You'll expand on the code you wrote in the previous chapter, finalizing the server-side portion of your mashup in this chapter. Over the next few pages, you will learn how to do the following:

• Create XML feeds of the geocoded Tourfilter data
• Add caching to speed up the geocoding process
• Use cron to automate the XML feed generation
