Educational applications of multi-client synchronization through improved Web graph semantics

The MMM (Multi-head, Multi-tail, Multi-client) browsing project is a continuing effort to bring stronger graph semantics to the World Wide Web, thereby increasing the Web´s usefulness for collaboration and education. The first modified browser provided facilities for links with multiple heads and tails, thereby giving the content author the ability to direct concurrent and synchronized browsing streams. The Web author can direct the paths of his readers and ensure that they visit pages in the correct context and order desired. Our most recent effort was the construction of a layer that filters content between the reader and the Web. This layer allows the ready composition of graph protocols so that Web content can be interpreted according to a variety of graph models. The model of the first project was expanded to be a full colored Petri net, thereby allowing synchronization of multiple browsing streams; the application of the MMM project to education now extends to a full collaborative classroom
