For the life science research data to be FAIR on NBDC information infrastructure in Japan

"Life Science Database Cross Search" is a knowledge infrastructure for life science researchers. This service was originally developed in Database Center for Life Science (DBCLS), and was transferred to National Bioscience Database Center (NBDC) in 2011. It provides a web search service across more than 670 public databases (containing 15 million entries). This open infrastructure supports the research data to be "FAIR". For instance, on the point of principle F2 (provided rich meta data) and F3 (indexed in searchable resource), which are difficult to achieve by each data provider or general search engine, our search system can fulfill the terms. Our infrastructure also accelerates the utilization of semantically integrated life science data.
