Abstract: A notification computer system can retrieve an event data element from a queue in an entitlement computer system. The event data element can represent a change to an entitlement record of a profile's entitlement to a computer service. The notification system can process the event data element, which can include accessing and applying a computer-readable rule data structure that governs processing of events from the event queue. The processing can also include generating a notification in a manner dictated by the rule data structure, with the notification indicating the change to the data structure represented by the event data element. The processing of the event data element may also include sending the notification to an entitled profile whose entitlement to a computer service is represented by the entitlement data structure.

Abstract: Common metadata exposure with digital images involves making image metadata types that are common across multiple image file formats accessible via an application programming interface (API). In an example embodiment, a browser exposes an image metadata API that may be called with reference to a preselected image metadata name. The browser determines an image metadata value that is associated with the preselected image metadata name from image metadata of a targeted image. When the image metadata value is returned to a caller of the image metadata API, the caller may consume or present the image metadata value in any manner.

Abstract: Specific metadata exposure with digital images involves making image metadata values associated with metadata type identification tags accessible via an application programming interface (API). In an example embodiment, a browser exposes an image metadata API that may be called with reference to a particular metadata type identification tag. The browser ascertains a particular image metadata value that is associated with the particular metadata type identification tag from image metadata of a targeted image item. When the particular image metadata value is returned to a caller of the image metadata API, the caller may consume or present the particular image metadata value in any manner.
