The Linked Data initiative continues to grow making more datasets available; however, discovering the type of data contained in a dataset, its structure, and the vocabularies used still remains a challenge hindering the querying and reuse. VoID descriptions provide a starting point but a more detailed analysis is required to unveil the implicit vo- cabulary usage such as common data patterns. Such analysis helps the selection of datasets, the formulation of effective queries, or the identi- fication of quality issues. Loupe is an online tool for inspecting datasets by looking at both implicit data patterns as well as explicit vocabulary definitions in data.
