Linked Open Data (LOD)

Linked Open Data (LOD) is data that fulfills the requirements of both Linked Data (LD) and Open Data: it is both linked and uses open sources.

5-Star LOD describes data that achieves ideal linked-ness and open-ness:

  1. ☆: Make your stuff available on the web under an open license
  2. ☆☆: Make it available as structured data (e.g., Excel instead of a scan of a table)
  3. ☆☆☆: Use non-proprietary formats (e.g., CSV instead of Excel)
  4. ☆☆☆☆: Use Uniform Resource Locators (URLs) to identify things, so that people can point at your stuff
  5. ☆☆☆☆☆: Link your data to other people’s data to provide context
