En el artículo Google working on advanced Web engineering se explica que Google está trabajando en la creación de una nueva plataforma de desarrollo web debido a las limitaciones que presenta la tecnología actual:
Despite its popularity, the Web offers only relatively primitive programming capabilities, compared to other platforms for delivering applications, such as Java or Microsoft Windows. One major shortcoming is that Web technologies don’t have a “common component model,” which slows code testing and reuse, he said.
As an example, Russell showed off a new element he created called commenting. For Web pages that allow user comments, the commenting element, rendered as a tag, can automatically format the text submitted by a user and even add an accompanying photo. The tag is actually a program, complete with its own API (application programming interface), Russell said. With the unified component model, HTML can be a sub-class of a larger environment, allowing for more ways to manipulate HTML code.
