Provenance is essential in scientific experiments. It contains information that is key to preserving data, to determining its quality and authorship, and to reproducing as well as validating the results. In complex experiments and analyses, where multiple tools are used to derive data products, provenance captured by these tools must be combined in order to determine the complete lineage of the derived products. In this paper, we describe a mediator-based architecture for integrating provenance
more &raquo; ... information from multiple sources. This architecture contains two key components: a global mediated schema that is general and capable of representing provenance information represented in different model; and a new system-independent query API that is general and able to express complex queries over provenance information from different sources. We also present a case study where we show how this model was applied to integrate provenance from three provenance-enabled systems and discuss the issues involved in this integration process.
