解析：语义web是一个数据组成的网络。我们现在每天使用大量数据。它们并不是网络的一部分。我可以在网上看我的银行结单。还有我的照片。我可以在我的日历上看到我的约会。但是我能在看日历里的照片时看到我照相时在干什么吗?我能在日历中看到银行授信额度吗?
为什么不能?因为我们并不是拥有一个由数据组成的网络。因为数据是由应用程序控制的，并且只为它自己维护数据。
语义web主要涉及了两方面。它是交换数据的公共方式，在最初的网络上我们只有交换文档的方式。它也是一种语言。这个语言记录了怎样将数据与现实世界对象相联系。这样就允许一个人或者一台机器，从一个数据库开始，在一系列无尽的数据库间移动，而这些数据库不是靠电线连接的。而是因为它们都是关于同一件事物的数据库。
