Provenance-Only Integration

As provenance records are collected from an increasingly diverse set of sources, the need to integrate them grows. The alternative approach of reconciling semantics scales when the records are queried infrequently. However, as the use of provenance grows, normalizing the diverse provenance via formal integration will yield better query performance. We describe two motivating cases for integrating provenance, provide an initial formal model for integration that is domain-agnostic, and identify a possible direction for optimizing the integration process itself.
