Consistent Interface for Entitlement Product

A distributed system operating in a landscape of computer systems providing message-based services defined in a service registry, the system comprising:

• a graphical user interface comprising computer readable instructions, embedded on tangible media, for a request to maintain a bundle of entitlement products, each entitlement product being a sellable product that describes a right to use a material or a service, the instructions using a request;
• a first memory storing a user interface controller for processing the request and involving a message including a message package hierarchically organized as:
• an entitlement product bundle maintain request sync message entity;
• and
• an entitlement product package including at least one entitlement product entity, wherein each entitlement product entity includes an object node sender technical identifier (ID), a change state ID and an internal ID, and wherein each entitlement product entity further includes at least one of:
• at least one description entity from a description package, at least one detail entity from a detail package, and at least one quantity conversion entity from a quantity conversion package;
• and
• a second memory, remote from the graphical user interface, storing a plurality of service interfaces, wherein one of the service interfaces is operable to process the message via the service interface.

A computer readable medium including program code for providing a message-based interface for exchanging information about entitlement products, the medium comprising:

• program code for receiving via a 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 a request to check whether maintaining a bundle of entitlement products is possible, the first message including a message package hierarchically organized as:
• an entitlement product bundle maintenance check request sync message entity;
• and
• an entitlement product package including at least one entitlement product entity, wherein each entitlement product entity includes an object node sender technical identifier (ID), a change state ID and an internal ID, and wherein each entitlement product entity further includes at least one of:
• at least one description entity from a description package, at least one detail entity from a detail package, and at least one quantity conversion entity from a quantity conversion package;
• and
• program code for sending a second message to the heterogeneous application responsive to the first message.
