I was at the Cassandra Summit conference last week I talked to the guys from Titan (ThinkAurelius) about their roadmap with the TitanDB property graph that they developed prior to being acquired by DataStax. While their opinion was clearly biased by their own work, they made a good point that if your ontology is sufficiently complex that it requires reification in order to add properties to a triple, it can significantly affect the performance of the triple store (which seems somewhat obvious). I was wondering, in your experience, can you estimate how significant that degradation might be (if it really exists), or does it depend on too many factors to answer?
