An interface for indicating the presence of inherited values in a document. The interface enables a user to rapidly determine if an audience specific document conforms to the expectations or requirements of an intended audience. The interface distinguishes between current, primary and secondary audience layer values through the use of color or any other mechanism that allows a user to quickly identify data that is missing and needs to be populated, changed or remain unchanged if the inherited data is suitable for the given audience. Using the interface, users can determine at a glance what information is inherited and what level of inheritance that information is from. Before generating an audience specific document targeted at a particular media type, an audience hierarchy may be created and utilized for entry and edit of data for a desired audience.

Audience specific document targeted at a particular media type are generated by accessing data from an audience hierarchy. When obtaining a data value for a particular audience, if that value does not exist for that audience then the audience hierarchy may be utilized to find the data value for an inherited audience. By adding regional, cultural or regulatory subdivisions within the audience hierarchy and inheriting large portions of existing audience specific data entries, a large number of audience specific documents may be generated with a minimal amount of data entry required. Audiences may be specified in a given order for traversal within the hierarchy and displayed in a data entry and editing application utilizing visual characteristics to inform a user if the value for a particular piece of data is inherited from another layer or utilized from the particular layer in use. Audience specific documents may be masked and accessed by payment.

Technologies are described herein for providing efficient backup of multiple versions of a data file using data de-duplication. A CDP module copies blocks of data of a specific block size from a current version of the data file to a master file maintained in a backup location for the data file. Only blocks of data not matching a unique data block already in the master file are copied. The CDP module then creates an anterior file in the backup location for the current version of the data file containing an ordered list of references to the unique data blocks in the master file. The order of the list of references is based on the order of occurrence of each unique data block in the modified version of the data file. Finally, the CDP module creates a posterior file in the backup location for the current version of the data file containing any remaining block of data in the data file that is less than the specific block size.
