Based on intensive discussions for an emergence of e-Journal reflecting recent data deluge of observation data, experimental data, calculated data and variously processed (copies/edited/compiled/modified/compressed etc. and merged) data, an interim report is given about preliminary studies of data journal which are going on to include long-term geomagnetic observations data, materials testing data and historical data in Data Science Journal as its data part. Critical issues of integrating associated data of no established transfer model for making decisions are studies so as to prepare guidelines for data journal. Based on these studies, an action plan for a new Data Science Journal is proposed.
