Provenance library for MATLAB

Provenance provides an implementation of the PROV Data Model in MATLAB. It provides serialization in PROV-N, PROV-JSON and RDF (Turtle and PROV-JSONLD), as well as export in graphical formats (PDF, SVG, PNG) through Graphviz.

Installation: See the instructions below.
Demo: See the example below.

This library is also part of SPM.

Installation

Simply unzip the archive and add the provenance directory to the MATLAB path.

Example

Using this example from PROV-DM: a document is edited by some editor, using contributions from various contributors.

>> p = provenance;
>> p.add_namespace('ex', 'http:/example/');
>> p.add_namespace('tr', 'http://www.w3.org/TR/2011/');
>> p.entity('tr:WD-prov-dm-20111215',{'prov:type','document','ex:version','2'})
>> p.activity('ex:edit1',{'prov:type','editing'});
>> p.wasGeneratedBy('tr:WD-prov-dm-20111215','ex:edit1');
>> p.agent('ex:Paolo',{'prov:type','prov:Person'});
>> p.agent('ex:Simon',{'prov:type','prov:Person'});
>> p.wasAssociatedWith('ex:edit1','ex:Paolo',{'prov:role','editor'});
>> p.wasAssociatedWith('ex:edit1','ex:Simon',{'prov:role','contributor'});

>> serialize(p,'provn')
ans =

document
  prefix ex <http:/example/>
