SHARP is a reasearch prototype aimed at harmonizing heterogeneous provenance graphs through reasoning (PROV inferences). PROV Constraints inferences rules have been implemented through the JENA forward chaining inference engine.
Several ontologies have been proposed to extend the multi-purpose PROV-O ontology, such as prov-one, wfprov. The mutiplication of PROV-extended vocabularies makes it diffcult to link and cross-exploit multi-systems provenance graphs. In addition, even if workflow management systems produce strictly PROV-O entities, there is no guaranty that the same classes and properties are used, which possibly leads to non joinable graphs.
With SHARP, our goal is to propose reasoning mechanisms to produce harmonized provenance graphs, that can be more easily linked together and shared.

SHARP is available as a standalone command line interface. Here is the description of the command line parameters :
usage: SharpTB [-h] [-i <input_file_1> ... <input_file_n>] [-s] [-v]
SharpTB is a tool to maturate provenance based on PROV inferences
-h,--help print the help
-i,--input_files <input_file_1> ... <input_file_n> The list of PROV
input files, in RDF
Turtle.
-s,--summary Materialization of
wasInfluencedBy
relations.
-v,--version print the version
information and exit
It can be used to infer PROV statements for a single provenance trace :
java -jar SHARP-1.0-SNAPSHOT-launcher.jar -i sample-data/provstore-114819.ttl -s
Or it can be used to interlink and harmonize cross workflow provenance traces, as demonstrated here :
java -jar SHARP-1.0-SNAPSHOT-launcher.jar -i sample-data/galaxy.prov.ttl sample-data/taverna.prov.ttl sample-data/sameas.ttl -s
Finally, the -s option generates a visualization of the resulting provenance graph, based on inferred prov:wasInfluencedBy predicates.
Sample results are available in the sample-results directory.
In the following screenshot, a workflow partly enacted on Galaxy and Taverna is depicted. While the left part of the graph, disconnected, represents hidden data from the user Galaxy history, the right part represents influence chain from an initial Galaxy bioinformatics worklfow to a Taverna post-processing workflow.
The project can be compiled as follows :
cd SharpProvToolbox
mvn clean install -Dmaven.test.skip=true
Then, when this jar is in your classpath, you can benefit from PROV inferences as follows.
An RDF PROV graph can be loaded with the JENA API :
String inputGraph = "Your PROV graph in TTL syntax";
Model data = ModelFactory.createDefaultModel();
InputStream stream = new ByteArrayInputStream(inputGraph.getBytes(StandardCharsets.UTF_8));
RDFDataMgr.read(data, stream, Lang.TTL);
Then, the inferences and blank node unification is performed as follows :
Model res = Harmonization.harmonizeProv(data);
Util.dumpPredStats(res); // prints the main predicates in the graph
Finally, we povides a basic visualization of the resulting PROV graph, based on the D3.js framework :
Util.writeHtmlViz(data);
Util.writeHtmlViz(res);
