This use case describes how to pre-populate metadata fields such as Date and Author at the point of content entry. The goal is to read any available invisible metadata that the system creates automatically and create corresponding user-editable metadata properties. This way editors don't need to fill all fields by hand. Tracked as DOCU-259@Jira.
Example scenario
- An editor creates a new article page.
- The system creates the page content node and sets hidden metadata such as
mgnl:authorid
andmgnl:creationdate
. - Some customized mechanism reads the metadata and sets corresponding visible metadata properties
author
anddate
under the page node. - When the editor opens the page and edits the article header dialog, the Author and Date fields are already populated.
Metadata on the Standard Article page
You can check the available metadata fields on a new page with the Query tool.

Mapping between system metadata and user editable fields
Some of them can be mapped to user-editable metadata fields.

Metadata on the Standard Article page
To do: Create a similar table for an image uploaded to DMS.
Creating custom metadata fields
To do: What to do if you can't find a system metadata field but you want to populate a default value anyway? This would be the case for example for setting the copyright on uploaded images always to the same value.
