An electronic file wrapper contains one or more files that are associated with virtual paths and conditional logic that collectively define a presentation sequence for the one or more files, access control, version control, and enables the reporting of usage metrics that are responsive to a variety of access request parameters. The file wrapper may include one or more of a file wrapper identifier, a version identifier, and an encrypted portion that contains the one or more files in encrypted form. The file wrapper identifier refers to the applicable and appropriate virtual path and conditional logic definitions contained within a database or other suitable information source that is independent of the file wrapper for a given set of access request parameters. The file wrapper may be constructed by an authoring application program or program component, and may be interpreted and presented by a viewer application program or program component. |
