We've reached the end of our discussion about the core components of OpenLayers. This was the last chapter that deals specifically with defining parts of the OpenLayers API. In this chapter, we discussed styling vector layers in OpenLayers. We covered the Style and StyleMap classes, and went over how to work with the Rules and Filter classes.

The next chapter will be similar to the latter part of this chapter. Instead of going over more of the OpenLayers library (you know enough now to be dangerous), we'll go over the process of creating a web application using OpenLayers. We'll put together the things we've learned throughout this book to demonstrate how everything 'fits together', and what a typical development process looks like.
