This paper presents PROV-O-Viz, a Web-based visualization tool for PROV-based provenance traces coming from various sources, that leverages Sankey Diagrams to reflect the flow of information through activities. We briefly discuss the advantages of this approach compared to other provenance visualization tools. PROV-O-Viz has already been used to visualize provenance traces generated by very dif...

Data provenance refers to the historical record of the derivation of the data, allowing the reproduction of experiments, interpretation of results and identification of problems through the analysis of the processes that originated the data. Data provenance contributes to the evaluation of experiments. This paper presents a framework for data provenance using the W3C provenance data model, call...

The prov family of documents are the final output of the World Wide Web Consortium Provenance Working Group, chartered to specify a representation of provenance to facilitate its exchange over the Web. This article reflects upon the key requirements, guiding principles, and design decisions that influenced the prov family of documents. A broad range of requirements were found, relating to the k...

This paper presents an extension to the W3C PROV provenance model, aimed at representing process structure. Although the modelling of process structure is out of the scope of the PROV specification, it is beneficial when capturing and analysing the provenance of data that is produced by programs or other formally encoded processes. In the paper, we motivate the need for such extended model in t...

6 Discoveries in modern science can take years and involve the contribution of large amounts of data, many 7 people and various tools. Although good scientific practice dictates that findings should be reproducible, in 8 practice there are very few automated tools that actually support traceability of the scientific method employed, 9 in particular when various experimental environments are inv...

In this paper, we propose a representation for PROV in JSON-LD, the JSON format for Linked Data, called PROV-JSONLD. As a JSON-based format, this provenance representation can be readily consumed by Web applications currently supporting JSON. As a Linked Data format, at the same time, it also represents provenance data in RDF using the PROV ontology. Hence, it is suitable for usages in both the...

Since its inception, the PROV standard has been widely adopted as a standardized exchange format for provenance information. Surprisingly, this standard is currently not supported by provenanceaware database systems limiting their interoperability with other provenance-aware systems. In this work we introduce techniques for exporting database provenance as PROV documents, importing PROV graphs ...
