Dynamic provenance for SPARQL updates using named graphs

Harry Halpin, James Cheney
2014 Proceedings of the 23rd International Conference on World Wide Web - WWW '14 Companion  
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.  ...  The authors, their organizations and project funding partners are authorized to reproduce and distribute reprints and on-line copies for their purposes notwithstanding any copyright annotation hereon.  ...

Using Provenance to Efficiently Propagate SPARQL Updates on RDF Source Graphs [chapter]

Iman Naja, Nicholas Gibbins
2018 Lecture Notes in Computer Science  
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.  ...

Towards fully-fledged archiving for RDF datasets

It also provides RDFev, a framework to study the dynamicity of RDF data. We use RDFev to study the evolution of YAGO, DBpedia, and Wikidata, three dynamic and prominent datasets on the Semantic Web.  ...  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.  ...  Acknowledgements This research was partially funded by the Danish Council for Independent Research (DFF) under grant agreement no.

Querying over Federated SPARQL Endpoints ---A State of the Art Survey [article]

Nur Aini Rakhmawati and Jürgen Umbrich and Marcel Karnstedt and Ali Hasnain and Michael Hausenblas
2013 arXiv   pre-print
SPARQL is the standardised query language for RDF, the default data model used in Linked Data deployments and SPARQL Endpoints are a popular access mechanism provided by many Linked Open Data (LOD) repositories  ...  Inspired by research results from traditional distributed databases, different approaches for managing federation over SPARQL Endpoints have been introduced.  ...  ., it only fetches remote graphs or graphs with the name in a local store. At present, the SPARQL 1.1 is the simplest solution to yield data from multiple sources.  ...

Towards fine grained RDF access control

Jyothsna Rachapalli, Vaibhav Khadilkar, Murat Kantarcioglu, Bhavani Thuraisingham
2014 Proceedings of the 19th ACM symposium on Access control models and technologies - SACMAT '14  
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.  ...
