Distributions

Download links

The dataset is published in a few size variants, each containing a specific number of stream elements. For each size, there are three distribution types available: flat (just an N-Triples/N-Quads file), streaming (a .tar.gz archive with Turtle/TriG files, one file per stream element), and Jelly (a native binary format for streaming RDF). See the documentation for more details.

Distribution size	Statements	Flat	Streaming	Jelly
10K	360,000	3.8 MB	1.9 MB	3.1 MB
100K	3,600,000	37.7 MB	18.8 MB	31.2 MB
