Consistent interface for feed event, feed event document and feed event type

摘要

A business object model, which reflects data that is used during a given business transaction, is utilized to generate interfaces. This business object model facilitates commercial transactions by providing consistent interfaces that are suitable for use across industries, across businesses, and across different departments within a business during a business transaction. In some operations, software creates, updates, or otherwise processes information related to a feed event, a feed event document, and/or a feed event type business object.

主权项

1. A non-transitory computer readable medium including program code for providing a message-based interface for exchanging information about events and user input for which users are notified in a feed system, the medium comprising:
program code for receiving a first message via a message-based interface derived from a common business object model, where the common business object model includes business objects having relationships that enable derivation of message-based interfaces and message packages, the message-based interface exposing at least one service as defined in a service registry, the first message received from a heterogeneous application executing in an environment of computer systems providing message-based services, the first message for querying information about feed events according to specified selection elements, the first message including a first message package derived from the common business object model, the first message package hierarchically organized in memory based on the common business object model, the first message package including:
at a first hierarchical level in the first message package, a feed event query message entity; andat the first hierarchical level in the first message package, a feed event package comprising, at a second hierarchical level in the first message package, a feed event entity, where the feed event entity includes, at a third hierarchical level in the first message package, a universally unique identifier (UUID), system administrative data, and at least one creation identity entity; program code for processing the first message according to the hierarchical organization of the first message package, where processing the first message includes unpacking the first message package based on the first message package's structure and the first message package's derivation from the common business object model, wherein the particular structure of the first message package is used at least in part to identify the purpose of the first message; and program code for sending a second message to the heterogeneous application responsive to the first message, where the second message includes a second message package derived from the common business object model to provide consistent semantics with the first message package.
