RDF or XML?
- Q: For a specific application, should I use XML or RDF?

- XML's model is

- applications may rely on hierarchy position (eg,
liin HTML) - relatively simple syntax and structure
- not easy to combine trees
- RDF's model is
- a loose collections of relations

- not easy to recover hierarchy
- easy to combine relations in one big collection
- great for the integration of heterogeneous information
- XML's model is
