4.2 data integration and aggregation RDF can be used for data integration and aggregation. Some RDF repositories are built by merging RDF triples from one or more locations, including other RDF repositories or non-RDF sources converted to RDF. Such an aggregations can be real or virtual. 4.2.1 Querying the Origins of Statements It must be possible for the query language and protocol to allow an RDF repository to expose the sources of the statements. Note: If may be possible for a triple to actually be present in multiple sources. 4.2.2. Querying Over Multiple Sources It should be possible for a query to specify which sources (as defined in 4.2.1) the query is executed against. If more than one RDF graph is specified, the result is as if the query had been executed against the merge of the specified RDF graphs. 4.2.3 Querying Multiple Repositories It should be possible to query multiple repositories.
