Introduction

OPMW is an ontology for describing workflows based on the Open Provenance Model. OPMW allows the publication of workflow execution traces as well as the more abstract reusable workflows that were originally used. Since the publication of the PROV-O standard, OPMW also extends the W3C recommendation.

Documents and applications

P-Plan documentation is released!

We are happy to announce that the Ontology for Provenance and Plans (P-Plan) specification is online: http://www.opmw.org/model/p-plan/.

P-plan is an extension of the PROV-O ontology created to represent the plans that guided the execution of scientific processes. P-Plan describes how the plans are composed and their correspondence to provenance records that describe the execution itself.

Examples

This pages aims to help you test our SPARQL endpoint. We propose some sample queries that can be posted in the form at the bottom of the page. The results obtained will grow as we keep publishing workflows.

The first example query retrieves the different templates available in the respository:

prefix opmw: <http://www.opmw.org/ontology/>
select distinct ?template where 
{
    ?template a opmw:WorkflowTemplate.
}

If we now are curious about the runs associated to each template, the query is:

Introduction to OPMW

OPMW is an ontology for describing workflows based on the Open Provenance Model. It has been designed as a profile for OPM, extending and reusing OPM's core ontologies OPMV (OPM-Vocabulary) and OPMO (OPM-Ontology). Since the publication of the PROV-O standard, the ontology also extends the W3C recommendation.
