what's the difference between these two areas? Does it mean that
GraphX/Giraph are only good to analyze large graph and draw statistics,
whereas I should use others like Fuseki/Marmotta if I want to build an
application (in the same way that I'd normally use PostgreSQL)?
Roughly - yes.
A lot of the activity (and hence investment) in the property graph space
is around analytics.
It's not a black/white divide. There are some pretty big RDF
installations (many billions of triples, these tend not to be web
accessible) doing analytics finding patterns in the data.
RDF emphasizes information modelling
Publishing data / separation of app and data
Knowledge graphs
Standard interchange formats
Property Graph emphasizes
Data capture
Graph analytic algorithms
Processing
