Provenance management in curated databases

Peter Buneman, Adriane Chapman, James Cheney
2006 Proceedings of the 2006 ACM SIGMOD international conference on Management of data - SIGMOD '06  
We describe an approach in which we track the user's actions while browsing source databases and copying data into a curated database, in order to record the user's actions in a convenient, queryable form  ...  General purpose database systems provide little support for tracking provenance, especially when data moves among databases.  ...  Jagadish, Val Tannen and Stijn Vansummeren for discussions on this work.  ...

PTSLGA: A Provenance Tracking System for Linked Data Generating Application

Kumar Sharma, Ujjal Marjit, Utpal Biswas
2015 International Journal of Information Technology and Computer Science  
In such cases, it is required for those applications to track, store and disseminate provenance information describing their source data and involved operations.  ...  In this article, we introduce an approach for tracking provenance of RDF resources. Provenance information is tracked during the conversion process and it is stored into the triple store.  ...  A system called BibBase [16] transforms bibliographic data stored in BibTeX files into Linked Data. RDF data are stored into a triple store which is available to be queried using SPARQL.  ...

A Provenance Model for Manually Curated Data [chapter]

Peter Buneman, Adriane Chapman, James Cheney, Stijn Vansummeren
2006 Lecture Notes in Computer Science  
In this paper we motivate and present a simple model of provenance for manually curated databases and discuss ongoing and future work.  ...  Existing models of provenance focus on queries/views in databases or computations on the Grid, not updates of databases or Web sites.  ...  Querying the data and its provenance "side-by-side" involves additional processing, since the data and provenance may be stored in separate databases.  ...

Tracing where and who provenance in Linked Data: A calculus

Mariangiola Dezani-Ciancaglini, Ross Horne, Vladimiro Sassone
2012 Theoretical Computer Science  
Linked Data provides some sensible guidelines for publishing and consuming data on the Web.  ...  Data published on the Web has no inherent truth, yet its quality can often be assessed based on its provenance. This work introduces a new approach to provenance for Linked Data.  ...  Query mechanism for picking out patterns in Linked Data are extended with provenance patterns, so that provenances can be exploited in queries.  ...

A demonstration of TripleProv

Marcin Wylot, Philippe Cudré-Mauroux, Paul Groth
2015 Proceedings of the VLDB Endowment  
In particular, the capacity to store, track, and query provenance data is becoming a pivotal feature of modern triple stores.  ...  In this demonstration, we present TripleProv: a new system extending a native RDF store to efficiently handle the storage, tracking and querying of provenance in RDF data.  ...  Section 3; in Section 4, we present our new provenance-aware query execution strategy allowing to store, track, and query provenance data; finally, we discuss our demonstration scenario, its user experience  ...

Adaptive RDF Query Processing Based on Provenance [chapter]

Marcin Wylot, Philippe Cudré-Mauroux, Paul Groth
2015 Lecture Notes in Computer Science  
Given the increasing amounts of RDF data available from multiple heterogenous sources, as evidenced by the Linked Open Data Cloud, there is a need to track provenance within RDF data management systems  ...  TripleProv is based on a native RDF store, which we have extended with two different physical models to store provenance data on disk in a compact fashion.  ...  This work was funded in part by the Swiss National Science Foundation under grant number PP00P2 128459 and by the Data2Semantics project in the Dutch national program COMMIT.  ...

Provenance in Sensornet Republishing [chapter]

Unkyu Park, John Heidemann
2008 Lecture Notes in Computer Science  
We explore the need for data provenance in this system to allow users to understand how processed results are derived and detect and correct anomalies.  ...  In that application, our link approach outperforms other alternatives on saving storage requirement and our incremental compression scheme save the storage further up to 83%.  ...  Thanks to Sung Jin Kim and Junghoo Cho for helpful comments on our preliminary version.  ...
