Bug #8827
synchronization doesn't update dateSystemMetadataModified if that's the only field that changed
0%
Description
It's been demonstrated that changing the dateSystemMetadataModified of an object's system metadata doesn't result in that change being synchronized with the CN unless there are other changes as well. Since in V2, the MN is authoritative for that field, the CN should perform a systemmetadata update command so it gets reflected on the CN.
Below is an example of what happens. Note that the object was picked up in the sync harvest, but then later ignored because nothing changed. Note that there are valid reasons to ignore updates with no changes, (resetting last harvest date), but this is not the same situation.

Look in class o.d.cn.batch.synchronization.type.SystemMetadataValidator.
There doesn't seem to be validators for filename and media type either.
