Multimodal layout and rendering

A computing system, comprising:

• a layout transformation component configured to:
• receive an environmental characteristic that indicates a display modality used for displaying a user interface display on a display device;
• receive application metadata for an application having a plurality of display components, wherein the application metadata is indicative of rendering instructions for rendering each of the display components and comprises component priority metadata that indicates a display priority for the plurality of display components;
• define a layout of the user interface display for rendering on the display modality, the layout comprising a canvas section configured to sequentially display the plurality of display components on the user interface display in response to a user input, wherein the layout transformation component defines an order for the sequential display of the plurality of display components based on the display priority for the plurality of display components;
• and
• a user interface component configured to instruct the display device to display the user interface display.

A computer-implemented method comprising:

• identifying a set of display components;
• receiving an indication of data bindings that bind data to the display components;
• receiving an indication of an environmental characteristic indicative of a given display modality used to display the data;
• selecting, based on the environmental characteristic indicative of the given display modality, a transformation template from a plurality of different transformation templates, each different transformation template including rendering instructions for rendering display components in a particular layout using a different display modality;
• identifying a set of canvas sections for rendering the user interface display using the given display modality, and each canvas section has an associated display priority;
• receiving component metadata, that is separate from the selected transformation template, for each of the identified display components, the component metadata including priority metadata indicating a priority of the identified display component;
• defining a layout for a user interface display of the identified display components that displays the data bound to the identified display components, wherein defining the layout comprises selecting, for each of the canvas sections, a display component from the set of display components based on the display priority of the canvas section and the priority of the selected display component indicated by the priority metadata;
• and
• generating rendering instructions for the user interface display.
