Historically, many evolutions of the world wide web have been adopted and used in internal webs. Just like the web evolved from a text-based system to a web of multimedia and online services, intrawebs now include multimedia resources and, for instance, corporate forms moved from online static copies to dynamic front-ends of web applications directly linked to the corporate information system. Even latest web tools meet application scenarios on corporate webs: wikis can be used to edit and maintain corporate documents and directories in a very simple way, blogs can be used for news and technological watch, web services are being used to allow enterprise application integration and workflow management, semantic web frameworks are used for information and data integration and exchanges for instance to materialize corporate memories as corporate semantic webs, etc.
