Before we take a closer look at what the Web Services Resource Framework (WSRF) is, we need to have a basic understanding of how Web Services work (so we can better appreciate how WSRF extends Web Services). If you're already familiar with Web Services, you can safely skip this section.

To do so, I could publish the weather information through a Web Service that, given a ZIP code, will provide the weather information for that ZIP code
