SST Core

SST Core is not a general purpose RDF toolkit
#

SST Core is highly optimised in various ways for speed and efficiency. To achieve this goal certain restrictions are introduced, with the result that SST Core is not a general purpose RDF toolkit. In practise this means, every RDF file generated with SST-Core is valid according to the W3C standards, but not every RDF file can be imported into SST Core.

In detail the limitations are:

  • every NamedGraph is identified by an URI (URN or URL) without any fragment
  • IBNodes are located in exactly one NamedGraph with the same base URI plus a fragment
  • NamedGraph IBNode has the same URI as the NamedGraph
  • every Datasets is identified by an URI (URN or URL);
  • the default graph of a Dataset is also a NamedGraph with the same URI as the Dataset
  • blank node can be referenced as object only within the same NamedGraph where they are defined
