  • The input file must be tab- or comma-delimited text with six columns as follows:
    Table Name of the table
    Field Label of the field as it appears in the data files. If this field is blank, the description applies to the table itself.
    Description Explanation of the field's contents; may be a definition or description
    Minimum Minimum value if the field is numeric (may be omitted)
    Maximum Maximum value if the field is numeric (may be omitted)
    Units Units of measure if the field is numeric (may be omitted)
    Source Value for Attribute_Definition_Source (may be omitted)
  • First line should contain column headings, delimited with comma or tab, just like subsequent rows.
  • You can try it with example-eainfo.csv.
  • Fields should be specified in the order they appear in the tables (column order).
  • The first line for each table should have an empty field name and its description should refer to the table as a whole.
