This paper explores the idea of using the W3 technology as an integration tool for building new applications. Most of the applications that we are willing to develop, specially in an industrial context, can't be built from scratch, but need to use existing software, existing data-bases, existing solutions. For example, we want to create communications between existing applications, or we want to provide access across the network to applications that can't handle such communications. We argue that the W3 and its related software is currently the best available tool for building this kind of applications.
Clients exist for almost every flavour of computer or system.
HTML provides most of the functionalities that are needed to interact with the user. HTML is very simple to teach, use, analyse or generate. No other existing tool is as universal and as simple to master. W3 provides a universal communication protocol. Simplicity is the rule.
