By widely opening access to intellectual assets, knowledge is hoped to circulate among people and be used, leading to more intellectual assets. However, compared to the wealth of information on the publication of intellectual assets, information on use cases of intellectual assets is scarce, and this is the “missing link” in the circulation of knowledge. We have been attempting to trace the missing link by developing the Mahalo Button, a platform for collecting and sharing use cases of datasets. We want to discuss the future image of the circulation of knowledge from publication to use.
