Flow-Based Provenance

Abstract

Aim/PurposeWith information almost effortlessly created and spontaneously available, current progress in Information and Communication Technology (ICT) has led to the complication that information must be scrutinized for trustworthiness and provenance. Information systems must become provenance-aware to be satisfactory in accountability, reproducibility, and trustworthiness of data. BackgroundMultiple models for abstract representation of provenance have been proposed to describe entities, people, and activities involved in producing a piece of data, including the Open Provenance Model (OPM) and the World Wide Web Consortium. These models lack certain concepts necessary for specifying workflows and encoding the provenance of data products used and generated. MethodologyWithout loss of generality, the focus of this paper is on OPM depiction of provenance in terms of a directed graph. We have redrawn several case studies in the framework of our proposed model in order to compare and evaluate it against OPM for representing these cases. ContributionThis paper offers an alternative flow-based diagrammatic language that can form a foundation for modeling of provenance. The model described here provides an (abstract) machine-like representation of provenance. FindingsThe results suggest a viable alternative in the area of diagrammatic representation for provenance applications. Future Research Future work will seek to achieve more accurate comparisons with current models in the field.

“…For the sake of a self-contained paper, the basic notions in FM are briefly described in the next section. The model has been utilised in software engineering (e.g., Al-Fedaghi, 2014, 2016a, 2016b, 2017a, 2017b, 2017cAl-Fedaghi and AlQallaf, 2017). Section 3 gives an example illustrating the features of the model.…”
