| Can you give example the practical implication of your research? |
Thank you for your question. One of the practical examples is that there are more than two different systems for open data management and each system needs to collect the metadata and data from other systems. |

| Will you tell us what is the major achievement of this paper, and also what is further study issue from this? Thanks in advance!! |
Thank you for your question. The major achievement of our paper is that we presented a flexible system with standard mechanisms for managing the harvesting process effectively. The further study issue we would like to focus on is the state controlling problem, especially in the object collecting stage. |

| Dear author, you have done a good research. What are the advantages of your system over other systems? What are the current shortcomings? What will future research focus on? What problems does your solution solve in the actual environment? |
Thank you for your question. In our experiments, our system actually has a better performance compared with the other solutions. However, one of the current shortcomings of our approach which we would like to improve in the future is the state controlling problem, especially in the object collecting stage. |
