About the use of CJ's RDF database

[sato oi]

I am in charge of digital archiving at Kokugakuin University Museum.
I would like to ask you about the use of CJ's RDF database.

We are currently constructing a search system using CJ's RDF database as a research tool.
The system is designed to search across all material data by material type, registered words, etc. However, due to the enormous amount of data on external sites and the complicated search logic, the response time is becoming unacceptable for practical use.
We would like to improve this problem by copying CJ's RDF database to our DB site's RDF database and searching it, while considering improvements to the logic. Is there any problem in using this kind of copying and publishing?
When we release the data, we will clearly state that the item in question is a copy of CJ's RDF database, that any discrepancies in the information should first be referred to our DB site, and that the use of the material data is subject to the terms of use stated on the source site.

We would like to thank CJ for their efforts.Thank you.
