Business object resources are accessed by a consumer application via web protocol. A business event occurring in a provider business application, which the consumer application is authorized to subscribe to, is identified. Each identified business event is assigned to a corresponding business object resource. Access to the business object resource is implemented as a RESTful application programming interface call. A uniform resource identifier is generated for accessing the business object resource affected by an occurring defined business event. At least one event message is created for the occurring defined business event, such that the event message includes the uniform resource identifier. The event message is published to all subscribed consumer applications that are identified as being interested in contextual information of the occurred business event, thereby enabling the calling of the RESTful application programming interface and to access the affected business object resource.
