mods:dateModified is useful for Websites or data sets. The MODS Editorial Committee proposes the addition of bf:Modification as a subclass of bf:ProvisionActivity (instead of bf:dateModified) since the modification of the resource may also include an agent for instance. With the addition of bf:Modification the date may simply be expressed using bf:date
How about: "Information relating to modification of a resource."
