What fields should be modifiable?

[stuartmcalpine]

This is a placeholder issue to revisit the modifiable functionality.

Left over thoughts from PRs

Potentially these columns could be modifiable:

Execution table

• description
• execution_start
• locale
• configuration

Dataset table

• the version and version suffix (as long as it doesn't clash)
• creation_date
• access_API
• description
• is_overwritable
• name (if it doesn't clash)

There is also owner and owner_type that could be changed. But these are potentially more similar to the promotion between schemas, like changing the owner would be like transfer.

• whether two values (True, False) for the modifiable field in the schema are sufficient or whether there should be a third, which allows a field to be modified only if something like force is specified
• exactly which fields should be in each category
