1. A computer-implemented method of versioning metadata associated with content for an object, wherein the metadata comprises data selected from the group consisting of information about a file size of the object, information about an author making a revision to content for the object, information about a title of the object, information about a revision date of the object, information about access security associated with the object, and any one or more combinations thereof, the method comprising:

  • receiving an updated value for the metadata and storing the updated value for the metadata separately from the content; and

    determining a modification indicator for the metadata based upon a comparison of the updated value for the metadata to previously stored values for the metadata, wherein the modification indicator provides a quantified value representing an indication of extent of differences between the updated value for the metadata and any one or more of the previously stored values for the metadata, and wherein the determination of the modification indicator further comprises determining a lineage value for the updated value for the metadata, the lineage value representing a change in a number of users associated with modification of the metadata from the previously stored values for the metadata to the updated value for the metadata.
