Abstract: A system receives a selection of a portion of digital content within a graphical user interface. The system traverses the entire digital content to identify a plurality of components associated with the portion of digital content, and applies at least one policy to each of the plurality of components to select those components necessary to recreate the portion of digital content. The system exports the portion of digital content and the plurality of selected components necessary to recreate the portion of digital content. The system then recreates the portion of digital content using the plurality of selected components necessary to recreate the portion of digital content.

Abstract: Methods and apparatus implementing a technique for adding an interface to a boss object at run-time. A boss object includes one or more interfaces and each interface has a corresponding implementation class. In general, in one aspect, the technique includes: reading a first boss class having a first interface, defined in a first software component; reading a second interface, defined in a separate second software component; and binding the second interface to the first boss class, so that instantiating the first boss class creates a first boss object including the first interface and the second interface.

Abstract: Methods and apparatus for performing file conversions. In one aspect of the invention, a conversion engine contained in a base program or application program performs conversions based upon “schemas” contained in one or more secondary programs, such as plug-ins. Optionally, the schemas describe each format in which the current and previous versions of the plug-in read and write data. The conversion engine optionally identifies the source and target schemas and outputs a streamed representation of the persistent data in a format compatible with the current version of the secondary program.
