Abstract
Techniques to manage collaborative documents are described. An application program may comprise a document render component to render a first document instance of a collaborative document, a document share component to receive a document update list comprising a set of change records for a second document instance of the collaborative document, and modify properties of one or more constructs for the first document instance based on the change records to form a merged document instance of the collaborative document, and an undo manager component to manage a local undo stack for the first document instance, the local undo stack comprising a set of undo records, and determine whether to preserve one or more of the undo records of the local undo stack after formation of the merged document instance based on one or more of the change records. Other embodiments are described and claimed.
