3 Linked Data: how it works
This lesson explains the essential points of how Linked Data works, without going into technical details. It explains what a graph is and why representing data as a graph is an essential ingredient of Linked Data. It contrasts knowledge representation and data representation languages.
This lesson also discusses the core principles of RDF and the reason RDF was designed to use URIs as names for things. A brief overview of the foundational standards is presented, again, without going into technical details.
The last module in this lesson recapitulates the four main features that make data interoperable. This will be the foundation for lessons to come.
The learning objectives of this lesson are:

- Appreciate the role of classes in knowledge representation
- Identify the core principles of RDF
- Appreciate the importance of how URIs are used
