Abstract :
During its life cycle, data has to go through different stages, from generation, storage, query, various processing, to deletion or archiving. Meanwhile, all these evolutions can be recorded by data provenance, which can be used for data deduction and credibility verification. Starting from the status of data application and processing, current problems exist in data management have been raised in this paper. Thus, in order to solve the problems, provenance information on space and time was discussed. Then, based on Open Provenance Model (Referred to as OPM), analysis and research were conducted, a more complete description model has been given, which contains time and space provenance information. With this model, it will be more convenient for data query and credibility verification in the following data management.
