One of the features of Web2 is built-in support for versioning of documents. This will allow you to access news and other topical data that has been archived, and improves the longevity of inter-document links [demo coming soon]
Web2's system of data packages can be used to automatically produce links to documents that may be elsewhere in a site's heirarchy, but are relevant to the current document, without the need to explicitly link every page in a package. [demo coming soon]
Web2 embraces the interactivity and fluidity of the web as a medium by integrating the publishing and authoring processes of web development. Web2 will also provide a more efficient platform for the development of web-based applications.
