WePIGE illustrates a new approach for extracting fine-grained provenance information from XML artefact-based workflow executions. The extraction framework relies on the usage of XPath mapping rules for inferring data and service dependency links [2]. This demonstration illustrates the usage of the WePIGE graphical user interface for exploring the provenance graph generated by a predefined set of mapping rules and for semi-automatically inferring new provenance mapping rules between user selected XML fragments.
