RSS and XML are cooler than you think. RSS is a simple Web 2.0 technology that completely changes our relationship with the web. Instead of having to go to the web, the web comes to you! If you learn nothing else about Web 2.0, learn RSS. It’s a great step toward what’s coming next. If you want to learn the next most important thing, learn XML, god’s gift to the web. XML is a character based data format that allows disparate systems to talk to each other. It is the heart of Web 2.0, which is righteous on so many levels. It is easy to get started; at no cost anyone can micropublish through a blog. These technologies are just the beginning. Keep your eye on these buzzwords: web services, service-oriented archicture, and the semantic web. Librarians are already talking about semantic libraries. There’s lots coming down the pipe.
Indeed! read the whole post. Thanks John.
