Field Value Revisions

Know at which revision a particular value changed (including in multivalue fields) in order to track the provenance and date of the value.

Features

Keep track of which entity revisions individual items in multivalue fields were added or changed on. Also of course keep track of which revision gave your content any value, including those stored in non-multivalue fields.

Post-Installation

At this point, some custom code. Specific feature requests welcome.

Additional Requirements

None known.

Recommended modules/libraries

Meta Entity module, specifically with Entity Meta Relation, might make a good companion.

Similar projects

• Changed Fields API, but it does not track changes among individual values: #3475122: Any functionality (or examples or advice) for comparing multivalue fields?
• Entity Log module but (in addition to not tracking values within multiple value fields) it does not store the revisions of the entities where the change occurred; the columns in its database table only have the ID and entity type of the changing piece of content, no version ID.
