1. A computer-implemented method for preserving a state of an application during update, comprising:

  • providing an initial document template tagged by a name and a version number to represent an initial state of the application;

    instantiating the application by providing a user with a copy of the initial document template, the instantiating yielding an instantiated document;

    allowing the user to interact with the instantiated document;

    performing a check for updates of the application; and

    updating the application if the currently instantiated document application version is not a latest available version of the application, as follows;

    obtaining a latest version of the initial document template;

    obtaining a transformation description for converting end-user data in the instantiated document to an updated schema format, if an end-user data schema of the application has been changed,creating a newly instantiated document on the latest version of the initial document template for the application,transforming the end-user data using the transformation description if one was given, placing the end-user data or transformed end-user data into the newly instantiated document, andreplacing the instantiated document for the application with the new instantiated document for the application in the end-user experience.
