RDF Reification Benchmark using the Biomedical Knowledge Repository (BKR)

This resource can be used for benchmarking different RDF modelling solutions for statement-level metadata, namely: 

- RDF Reification,

- Singleton Property,

- RDF* (RDF star). 

The dataset contains 3 different versions of the Biomedical Knowledge Repository (BKR) knowledge graph, as described in:

Vinh Nguyen, Olivier Bodenreider, Amit Sheth. "Don't Like RDF Reification? Making Statements About Statements Using Singleton Property" WWW 2014, doi: 10.1145/2566486.2567973.

and,

The 3 knowledge graphs dumps are packaged as Gzipped RDF files in Turtle (and Turtle*) syntax. 

BKR-R-fullKGdump.ttl.gz for the Reification method,

BKR-S-fullKGdump.ttl.gz for the Singleton method,

BKR-star-fullKGdump.ttls.gz for the RDF* method.
