Patent ID: 8515794

Claim:
A non-transitory computer readable medium including program code for providing a message-based interface for processing and exchanging information for employee time events, including events on a given date and at a given time that starts or ends for an employee, the medium comprising: program code for receiving 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 and from a heterogeneous application executing in an environment of computer systems providing message-based services, a first message for requesting the creation of a bundle of employee time events for an employee that includes a first message package derived from the common business object model and hierarchically organized in memory as: an employee time event bundle create request message entity; and at a first hierarchical level within the first message package, an employee time event package comprising an employee time event entity, where the employee time event entity includes, at a second hierarchical level within the first message package, an employee time recording card identifier (ID), an employee universally unique identifier ID (UUID), a type code, a date time, a reason code, and an employee time recording device ID; 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 common business object model; 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.
