Abstract: Document version interoperability is provided by allowing members of a community to maintain independent migration by permitting the members to continue to run native application software on their respective systems. A community may define a community version by establishing certain rules for documents. When electronically transmitting a document, a member of the community may provide in the transmitted message containing the document his native version of the document, the community version of the document, as well as any or all versions of the document which are closer to the community version of the document than his native version of the document. This may be accomplished by performing document transformations when creating the message. Upon receipt of the documents, the recipient may choose the document version contained in the message that is most easily read by the recipient's native application program and transform it so that it may be opened by the recipients native application program if necessary.
