This talk provides an overview of types of applications built on Linked Data, a framework for assessing tools used for building those applications, and a vocabulary to describe visual applications developed on top of LOD for more interoperability and components reusability. Our proposal derives from a study of applications in dierent domains built in Open Data initiatives in UK, US and France. We identify two benets of our approach: (i) it could help building a sustainable ecosystem of visual applications making use of 4-5 stars datasets, and (ii) it could make it easier to find application patterns used for creating Linked Data Applications.
