Technical Report
Discovering information on the Web in a scalable and reliable way is an important but often underestimated task. Research on discovery itself is quite a young field. Hence, to date not many Web-compliant discovery mechanism exist. Firstly, we introduce a layered Abstract Discovery Model and discuss its features. Then, driven by use cases and requirements, we review three promising discovery proposals in the context of the Web of Data and the Web of Documents: XRD, POWDER, and voiD.
