- Learn to expect the unexpected
--> RDF data missing properties or having more than one property...
it's valid!
- Take into account reification
--> rdfs:seeAlso and dc:title
- Take into account containers (collections, seq, ... ) as much as
possible, ignore if not used
--> Could have been used for rdf:seeAlso in bookmarks
- RDF can be serialized in any way and still be legal
--> Don't assume an XML structure order (as RSS does)
- RDF allows to combine different properties and aggregate more as needed
--> if it breaks, it probably has a modelizing problem
- Moving RDF stores or files can be complex
