Here we show the structural changes in the connections among (1) the variables in data jackets (2) words in the expected outcomes of data use, and (3) supposed data use (analysis/simulation) scenarios represented in the 1603 data jackets stored from 2014 through 2018 (business years). These respectively mean (1) the features of data to be provided or created, not necessarily on the allowance to share the data contents, (2) the social expectation about how and for what the data can be used if shared, and (3) the main process of data use. The changes in the structure of the co-occurrence are visualized by use of the traditional sequence of graphs with KeyGraph, where we found that the connections are emerging for the recent two years, that means the ideas of data users are evolving with communication in IMDJ.
