document: The two cultures : mashing up web 2.0 and the semantic web A common perception is that there are two competing visions for the future evolution of the Web : the Semantic Web and Web 2.0 . A closer look , though , reveals that the core technologies and concerns of these two approaches are complementary and that each field can and must draw from the other 's strengths . We believe that future web applications will retain the Web 2.0 focus on community and usability , while drawing on Semantic Web infrastructure to facilitate mashup-like information sharing . However , there are several open issues that must be addressed before such applications can become commonplace . In this paper , we outline a semantic weblogs scenario that illustrates the potential for combining Web 2.0 and Semantic Web technologies , while highlighting the unresolved issues that impede its realization . Nevertheless , we believe that the scenario can be realized in the short-term . We point to recent progress made in resolving each of the issues as well as future research directions for each of the communities .
