TwoPhaseSparql

From W3C Wiki
Jump to: navigation, search
  • Phase One : CONSTRUCT over source graph/datasets
  • Phase Two : SELECT over result of Phase One

The result of Phase One may use completely different vocabularies than the source graph, hence Phase Two needn't be domain-specific. Can help separation of concerns, e.g. query from presentation.
