Towards Collaborative Portable Web Spaces

As two recent trends in Web development, Widgets and mashups, are converging, we claim that there is a growing need to define a Widget Space configuration language to allow building flexible personal learning environments that could be independent of a runtime environment. By integrating the do-it-yourself dimension of a Web portal or Web mashup and the social dimension of the Web, we describe the scenarios that could emerge and we describe the new Web components that would be required to support it.
