The 5th EUCLID webinar focuses on technologies and approaches towards exploiting Linked Data by building LD applications. First, we provide an overview of the main types of linked data applications and list examples of popular existing applications. Then, we describe a generic layered architecture of a linked data application and main technologies used to support it. Furthermore, we give details on existing frameworks which help to develop such applications in a structured way. Finally, we describe how the web APIs can be used to support data exchange for a linked data application.
