Abstract
Since it is difficult for curators who are not information field specialists to provide teaching materials on the Internet, we built a content management system to support the delivery of teaching materials on the Internet. Specifically, our system, which allows correspondence between various platforms, considers the distribution method of teaching materials in cooperation with an actual planetarium program. As a result, curators effectively utilized the Internet and distributed teaching materials. To clarify the usefulness of this research, the curators of the Nagoya City Science Museum used and evaluated the system.
