Abstract: Review, comparison, modification, and/or merging of multiple sources of data associated with media content are facilitated. Multiple documents can be simultaneously reviewed with a base document, and the changes or differences associated therewith can be flexibly reviewed, compared, accepted, and/or rejected to efficiently generate a new document having the changes or differences merged. Documents can be reviewed compared, modified, and/or merged based on sections of the base document. Efficient and selective search-and-replace of data associated with media content in files of various data sources or locations is thus enabled for a wide array of document tasks.

Abstract: Media content is parsed and content units of the media content are separated from its presentation data. The content units can be stored in a separate repository, such as a database, or repositories, such as with cloud storage, from where the content can be shared across various other electronic documents or other media contents. The content sections or “units,” are replaced within the media content or electronic document by references to the content in the content repository or repositories. The modified media content or electronic document with references can be stored in a separate section of the content repository or repositories or a different repository. To render the media content when requested or in response to a request by a user, the content and presentation information of the media content can be retrieved from their respective repositories and media content is synthesized, or otherwise put together.
