[...] incremental semantic lifting of data. [...] We capture provenance (using the latest W3C working draft) by making views over datasets immutable and tracking differences between views (effectively allowing sharing of data between views). The meta-information pertaining to provenance and each data view is itself stored in RDF and can be made externally visible.
