The Web has been a remarkable technology that has promoted knowledge sharing in scholarly environments. Institutions and their researchers share information with readers via ad hoc home pages, structured portals, information databases and repositories. However, an external service still needs to create a sophisticated data mining application in order to be able to compare and contrast different research or teaching activities from a range of institutions. Even OAI-PMH has not solved the problem of exchanging metadata between data providers and service providers. Instead, we need to adopt Semantic Web techologies to reliably and accurately share information between institutions, repositories and services. Web 2.0 has encouraged social networking and the creation of "mashups" (the combination of data from various sources to provide new applications such as that plots data from public repository registries onto a Google Map). The Semantic Web makes mashups easier to achieve, and will ultimately help researchers understand and interpret the complex scholarly networks of citation, funding, influence and esteem that constitute the academic landscape in which we operate.
