Abstract
Keeping track of the history of subsurface data and how they were generated is a challenge that the industry is facing. We intend to address this challenge through the notion of data provenance, considering seismic interpretation as a case study. We build and extend on the W3C PROV-DM to capture the history of multi-user interpretations and their quality. Our extension included the introduction of new namespaces, named geo and interpret, to accommodate new qualified names for the concepts presented by the model. This provenance model was implemented as a fine-grained relational database model and integrated into a data-centric visualization architecture. A prototype application allowed our users to visualize provenance information on each point by hovering above a horizon feature.
