Smart slide creation and presentation

A non-transitory computer-readable medium that stores machine executable instructions, where execution of the instructions results in performing operations that comprise:

• creating a presentation comprised of at least one sheet, each sheet containing one or more visual elements, where in response to input from a user, representing visual elements as depictions in a model, where the model is comprised of a visual model that operates with a view layer, a content model, and a mapping model that provides mapping rules between contents of the visual model and the content model, where each depiction depicts an item in the model, where each item is a unit of information with a unique identifier, where each item can be depicted by at least one depiction and each depiction defines the visual representation of the item's information via the visual element;
• for a case where the presentation is comprised of a plurality of sheets, and in response to a change to an item made by altering the visual element in the view layer that is associated with the depiction of the item, operating the model to perform computation in accordance with the stored machine executable instructions so as to automatically propagate the change to the item to all other occurrences of depictions of the item across all sheets of the plurality of sheets of the presentation;
• and
• further operating the model for automatically updating the associated visual elements to reflect the change to the item.

A system configured to execute a presentation application to create a presentation comprised of at least one sheet, each sheet containing one or more visual elements, the system comprising at least one data processor coupled with at least one non-transitory computer-readable medium that stores machine executable instructions, where execution of the instructions by the at least one data processor results in performing operations that comprise:

• in response to receiving input generated by a user with a user interface coupled to the at least one data processor, representing visual elements that are displayable to the user via the user interface as depictions in a model, where the model is configured in at least one storage medium so as to be comprised of a visual model that operates with a view layer, a content model, and a .mapping model that provides mapping rules between contents of the visual model and the content model, where each depiction depicts a single item in the model, where each item is a unit of information with a unique identifier, where each item can be depicted by at least one depiction and each depiction defines the visual representation of the item's information via the visual element;
• for a case where the presentation is comprised of a plurality of sheets, and in response to a change to an item made by altering the visual element in the view layer that is associated with the depiction of the item, operating the model to perform computation in accordance with the stored machine executable instructions so as to automatically propagating propagate the change to the item to all other occurrences of depictions of the item across all sheets of the plurality of sheets of the presentation;
• and
• further operating the model for automatically updating the associated visual elements to reflect the change to the item.
