As a challenge of digital humanities in the future, we discuss the issue of creating a research program that proposes a monumental challenge, offers many researchers a chance to share resources and knowledge, and collectively tries to find solutions. Motivation behind this challenge is expectation for collective research based on co-creation beyond individual research based on competition. Recent trend in open science raises interests on improving performance of research collectively than individually through grand challenge research or contest-based research among a group of researchers, or trans-disciplinary research with participation of citizens and companies. Hence this paper discusses the concept of co-creative research in digital humanities, centering on open data released from Center for Open Data in the Humanities (CODH).
