Records in Onna will have many dates associated with them, and there are many metadata dates in general.

At Onna, we index and display two primary metadata dates on a document, the date created and the date modified.

These dates are set in the following precedence:

  1. Source Dates (i.e., Sent Date from Gmail or Slack gets set for both the parent and the attachment) as the creation date because this is when the document was created in the source.

  2. Document Processing Dates - dates embedded in the document’s metadata itself and extracted through processing (note that not all document types will have these dates)

  3. Document Creation in Onna (as the last option)

Many document formats do not maintain internal metadata, so they will not have their own created date. If a document does have additional metadata date fields, those are parseable on export by looking at the “Metadata” → “Other Metadata” section.

In a sample docx document we have a few dates in this section:

  1. meta:creation-date: "2020-10-26T20:11:00Z"

  2. meta:print-date: "2016-02-10T19:37:00Z"

  3. meta:save-date: "2020-10-27T19:14:00Z"

  4. Last-Modified: "2020-10-27T19:14:00Z"

  5. Last-Printed: "2016-02-10T19:37:00Z"

  6. Last-Save-Date: "2020-10-27T19:14:00Z"

And the document is sent as an attachment to the email at: "2020-10-28T15:26:24+00:00"

The origin creation date however gets set:

origin_date_created: "2020-10-28T15:26:24+00:00"

One thing to note with Word documents, in particular, is that creating a document from a template will transfer some of that metadata, as you see with the “print date”.
