Important note: If you do a CSV export of existing items from Hyacinth, and then edit that CSV and set new values for the _publish_targets-X.string_key fields, then you are overwriting the current set of publish targets.  So if an object originally had three publish targets, but you submitted a CSV with only two _publish_targets-X.string key columns (e.g. _publish_targets-1.string_key and _publish_targets-2.string_key), you would be UN-publishing it from one of the three original publish targets.

Important note: If a field contains a colon (:), that means that the field is a part of a field block. If you update one of the fields in the block, you must include all the fields in the block in the import spreadsheet or Hyacinth will assume the other fields in the block have null value. This can cause you to lose data as empty columns overwrite existing data. For example, here is a field block of parent publication fields. You can tell they are in a block because they have the same prefix ("parent_publication-1:").

• parent_publication-1:parent_publication_doi
• parent_publication-1:parent_publication_issue
• parent_publication-1:parent_publication_page_end
• parent_publication-1:parent_publication_page_start
• parent_publication-1:parent_publication_title-1:parent_publication_title_sort_portion
• parent_publication-1:parent_publication_volume

If you would like to update information in one of these fields using a spreadsheet created by csv export, do NOT delete the other columns that are a part of your block. Leave the existing data in the other columns and include all the columns in your import spreadsheet.
