The fundamental concept of VoID is the dataset. A dataset is a set of RDF triples that are published, maintained or aggregated by a single provider. Unlike RDF graphs, which are purely mathematical constructs [RDF-CONCEPTS], the term dataset has a social dimension: we think of a dataset as a meaningful collection of triples, that deal with a certain topic, originate from a certain source or process, are hosted on a certain server, or are aggregated by a certain custodian. Also, typically a dataset is accessible on the Web, for example through resolvable HTTP URIs or through a SPARQL endpoint, and it contains sufficiently many triples that there is benefit in providing a concise summary. Since most datasets describe a well-defined set of entities, datasets can also be seen as a set of descriptions of certain entities, which often share a common URI prefix (such as http://dbpedia.org/resource/). In VoID, a dataset is modeled as an instance of the void:Dataset class. Such a void:Dataset instance is a single RDF resource that represents the entire dataset, and thus allows us to easily make statements about the entire dataset and all its triples. The relationship between a void:Dataset instance and the concrete triples contained in the dataset is established through access information, such as the address of a SPARQL endpoint where the triples can be accessed.
