Publishing a dump of a large datasets that was integrated or extracted from different sources, while keeping source information intact.

Some all load them into a single graph, some keep them carefully separate, some only load the contents of a carefully selected subset of the graphs in the dataset, some run a transformation process that takes context information into account in order to derive a new integrated RDF graph, etc etc etc
