How to get RDF data?

• Of course, one could create RDF data manually…

• … but that is unrealistic on a large scale

• Goal is to generate RDF data automatically when possible and “fill in” by hand only when necessary

• Various data formats should be considered

• • databases (relational or otherwise)
  • data in XML, HTML, in pictures, videos, etc

• Details of the process is still subject of very active R&D!
