Very usefull, thx!! (also having many discussions on this in NL: should we use quads or is semantics too unclear yet? (ref.). If reification how to keep all redundancy in sync, etc.)

Our work will be presented in the Workshop on Scalable Semantic Web Knowledge Bases Systems. You can read our results here: http://users.dcc.uchile.cl/~dhernand/research/ssws-2015-reifying.pdf Cheers, Daniel Hernández On Thu, 2015-08-27 at 15:11 +0000, Patrick Hoeffel wrote: > All, > > I know this is not a new topic, so hopefully there is a reference to > the de-facto standard answer on this (that I have not been able to > find on my own so far). > > When I have a Subject that I want to store additional information > about, I can just add triples using the same Subject.
