Dynamic provenance for SPARQL updates using named graphs
2014
Proceedings of the 23rd International Conference on World Wide Web - WWW '14 Companion
Preserved Fulltext
While the Semantic Web currently can exhibit provenance information by using the W3C PROV standards, there is a "missing link" in connecting PROV to storing and querying for dynamic changes to RDF graphs ...
The primary contribution of this paper is a semantic framework that enables the semantics of SPARQL Update to be used as the basis for a 'cut-and-paste' provenance model in a principled manner. ...

Hence, only SPARQL updates are communicated, the need for complete re-derivation is done away with, and provenance is kept at the graph level making it better scalable. ...
RGPROV allows us to understand the dependencies a graph has on its source graphs and facilitates the propagation of the SPARQL updates applied to those source graphs through it. ...
Finally, they may be extended to deal with source graphs which use different entailment regimes. ...

It expresses provenance metadata via the Provenance Ontology and saves deltas in separate named graphs as SPARQL update strings. ...
Moreover, the leading knowledge bases – DBpedia, Wikidata, Yago, and the Dynamic Linked Data Observatory – do not use RDF to track changes and enable time-agnostic queries. ...
However, named graphs have a limit: they do not allow managing the provenance of implicit triples in the presence of update queries. ...

The dynamicity of RDF data has motivated the development of solutions for archiving, i.e., the task of storing and querying previous versions of an RDF dataset. ...

We extend SPARQL with a new query form called SANITIZE which comprises a set of sanitization operations that are used to sanitize or mask sensitive data within an RDF graph. ...
In order to make data sharing and integration pragmatic for Semantic Web, we present a query language based secure data sharing mechanism. ...
APPENDIX
SPARQL UPDATE vs SANITIZE The intent of the SPARQL UPDATE operation as its name suggests is to refresh the truth value, and is designed for that purpose by using Insertion and/or Deletion. ...
