Lineage

This URL provides the access to the most recent output from the database. The output is being overwritten as often as possible.

This data set was output from J-CORES database by using its complete Bulk Export function Version 1.9.9 from 2018-01-23T17:20:03Z till 2018-01-23T17:20:17Z. The specification of the outputs is available to be referred. Bulk Export gives a file bulk.csv with various attachment files (e.g. image files). Files bulk-something.csv are generated by picking some kinds of data from bulk.csv. Files something.zip consist of bulk-something.csv and related attachment files. Files bulk-something.csv are in character encoding UTF-8 with line ending characters CRLF. The database has a flexibility to store numerical/text values and attached files for user-defined parameters, which are output into User-Defined Parameter column group in bulk.csv.
