Abstract: Described herein are techniques for efficiently upgrading product information stored on a client device to the latest version that reflects the current products offered by a particular establishment. Product information changes frequently, which could result in large upgrade packages. Yet, the time available for downloading the packages onto a device may be severely limited. To improve download time, upgrade packages may be shard based on product commonality within different predefined scopes. For instance, information related to products common across chain-wide establishments may be upgraded using one set of upgrade packages, and information related to products common across region-wide establishments may be upgraded using another set. This upgrade framework helps reduce file size and leverage the edge-caching capabilities of content delivery networks to reduce the time needed to transmit upgrade packages to client devices.

Abstract: In one embodiment, a method includes identifying a pre-determined number of items associated with one or more entities; transmitting item information associated with the pre-determined number of items to a client device; and determining that the client device is likely to enter a first entity of the one or more entities. The first entity is identified based on a physical proximity between the client device and the first entity. The method also includes accessing, based on the first entity, location-specific item information associated with one or more of the pre-determined number of items or one or more additional items; and transmitting the location-specific item information to the client device. The item information and the location-specific item information are configured to be used by the client device while the client device is within the first entity.

Abstract: Technologies are described herein for document collaboration by transforming and reflecting a document object model. A DOM representation of a document to be shared is obtained at a host computer, transformed, and reflected to one or more participant computers. Each of the participant computers receives the DOM representation of the document and renders and displays the DOM representation locally. When the DOM representation is modified, changes to the DOM representation may also be transmitted to the participant computers, rendered, and displayed. Events occurring with respect to the DOM may also be synchronized between the host and participant computers.
