Abstract: Algorithms are provided to determine a final sequence of objects based on separating the objects from a base sequence and two derived sequences into common objects appearing in all three sequences and non-common objects missing from at least one of the sequences, then determining the final order of the common objects, and using the positioning of the non-common objects relative to the common objects in the original sequences. The final sequence represents changes made by the two derived sequences to the base sequence.

Abstract: A conversion tool that is automatically launched enables file formats not understood by a given application to be opened by that application. The converter registers for file types that are not already associated with an application used by the system. When a file that is not supported by another application is opened, the converter automatically converts the file to the target format and then opens the file causing the application that is registered for the target format to be launched.

Abstract: Tools and techniques for synchronizing metadata and document content across client systems using different communication channels are provided. These tools may define logical communication channels between client software components, and may allocate one of these channels to synchronizing updates to the contents of documents shared between these client components. These tools may allocate another one of the communication channels to synchronizing metadata between the client components, with the metadata describing activity pertaining to the shared documents. The client components may receive indications of activity made by users to the document contents, and may create metadata representing the activity. These client components may then transmit this metadata, using the further communication channel, to any number of other client components automatically in real time with the updates.
