Linked Data
• The basic assumption behind Linked Data is that the value and usefulness of data increases the more it is interlinked with other data. In summary, Linked Data is simply about using the Web to create typed links between data from different sources.

• We set up exact and close matches to concepts in many other thesauri
• It requires that each included concept has a persistent URL on the Internet
