Abstract

Introduce provenance and research issues in this area, describe provenance management framework consist of common provenance model and set of provenance query operators supported by a query engine. A naive engine is impractical for queries over large scientific datasets(why???). A new class of materialized view has been defined using provenir model, call MPV for query optimization. One example from Neptune project significantly reduces provenance query time. Heterogeneous data format from escience.
