I'm using the Stack Exchange Data Dump and am trying to have posts along with the creators of the posts. I would like to put text like "created on [date] by [user]". In most cases, the fields
LastEditorDisplayName are null.
Is this intentional? If so, why is the name only available in some cases?
Also, the readme that shows which fields are available is missing
OwnerDisplayName. I found it from the post Database schema documentation for the public data dump and SEDE.
