I suppose Jena SDB could be considered a proven approach. It's in fairly wide production use, although no longer in active maintenance: https://jena.apache.org/documentation/sdb/index.html --- A.

The vast majority of these provide RDBMS or Document-Object stores. Hence any proven approaches would be useful to have publicly available. > > On Wed, Nov 2, 2016 at 2:24 PM, Bernadette Hyland <bhyland@3roundstones.com> wrote: > Hi Ai-jun, > Not sure that storing RDF triples in a relational database is novel, at least not in 2016. And 300M isn’t a big number in the world of graph databases. For example, we’re working with a linked data repository, PubChem with 99B triples, and linking it to a subset of environmental linked open data. Point is, graph databases are a useful tool for specific jobs, just like RDBMS’s are great for other jobs. > > More importantly, getting triples out in a speedy manner, using a standard query language, and building a nice UI, is the part many people in the linked data community have spent 10+ years getting right. > > Just my 2 cents. > > Cheers, > > Bernadette Hyland > CEO, 3 Round Stones, Inc. > > > >> On Nov 2, 2016, at 04:11, Li, Ai-jun <Ai-jun.Li@morganstanley.com> wrote: >> >> >> I came across a very old request for comments for storing RDF data in relational database (http://infolab.stanford.edu/~melnik/rdf/db.html). I was unable to find any newer discussion on this. We had implemented a very innovative way of storing linked graph data in Sybase many years ago and the system is still being used today. The system is storing the equivalent of over 300 million triples and is scalable for much more. We’d be happy to share our approach if this is something the community is still interested in (will need to get the firm’s approval, obviously). >> >> Thanks, >> Ai-jun Li >> Morgan Stanley | Enterprise Infrastructure >> 1 New York Plaza, 16th Floor | New York, NY 10004 >> Phone: +1 646 536-0765 >> Ai-jun.Li@morganstanley.com >> >> >> >> >> NOTICE: Morgan Stanley is not acting as a municipal advisor and the opinions or views contained herein are not intended to be, and do not constitute, advice within the meaning of Section 975 of the Dodd-Frank Wall Street Reform and Consumer Protection Act.
