The release of Drupal 7 was a long time in coming and is a major upgrade from and means major changes for anybody used to working with Drupal, the popular content management system and web application framework. Every major version number means lots of new features, but also breaking changes making upgrading possibly tricky depending on how your site is set up. It also means that you need to know what the benefits are of the new version before deploying Drupal. In an attempt to address this need Packt Publishing have released Drupal 7 First Look by Mark Noble and were kind enough to send me an electronic review copy.
The Semantic Web is the concept that you can add machine readable meaning to you website to make it easier for computers as well as humans to understand what is going on with your content. If you look at this page you will find it easy to tell which part of the page is blog content, where my name is etc., but for a machine this is not so easy, they will only see something like “bla bla bla TITLE bla bla bla” and often will be limited to trying to find content based on keywords. The whole Semantic Web idea is the subject of major research efforts and much debate over how far it can go, but the good news for Drupal site administrators and readers of their websites is that Drupal 7 will be offering support for some of this technology out of the box.
