Abstract: A directory includes information about various systems (e.g., applications, processes, tasks, objects, services) and data, and may include data ownership information. The directory may define existing systems, corresponding locations by address, and corresponding semantic names. The directory may also specify the role of each system, e.g., a consumer or provider role. The directory may also define a scope of data a provider system can provide. As such, the directory may also include information about whether and how such data is being replicated. When a user requests data, a service may, based on the directory, determine and select an appropriate provider system for the data. The service may further create a subscription process to provide the user a local cache of the requested data. With such directory information, a service can provide data access services that integrate subscription processes.

Abstract: A request is received to initiate an operation (e.g., a query, etc.) on a view on a business object type. Such a request contains data characterizing the view which in turn characterizes a plurality of hierarchically arranged elements. Such elements characterized are associated with elements characterized by one or more business objects types. Thereafter, the operation is performed on the elements of the two or more business objects types. Responsive results of the operation responsive are mapped to the elements of the virtual business object type. After such mapping occurs, a message is generated that contains the results of the request in a structure compatible with the view.

Abstract: The subject matter disclosed herein provides methods and apparatus, including computer program products, for determining keys for use with data structures, such as objects, business objects, view business objects, and the like. In one aspect, there is provided a computer-implemented method. The method may include determining a first key of a view business object node by combining one or more keys of the business object nodes used to form the view business object node, the first key used to identify the view business object node when the view business object node is a root node. The method may also include determining, when the view business object node has a parent node, a second key of the view business object node by combining the first key and at least one key of the parent node, the second key used to identify the view business object node.

Abstract: A directory includes information about various systems (e.g., applications, processes, tasks, objects, services) and data, and may include data ownership information (e.g., data scope, read-write access, master-copy, etc.) and system role information (e.g., consumer or provider role). The directory may define existing systems, corresponding locations by address, and corresponding semantic names. With such information, a service may create routing rules that may provide the requested data via a semantic-based request. The routing rule may be selected to optimize communications and/or response time.

Abstract: Methods and apparatus, including computer program products, for providing a query object. In one general aspect, a query object includes an attribute uniquely identifying the business object. The query object includes an interface that includes at least a service that provides, to a calling application, information that specify a group of one or more instances of one ore more business objects. A calling application uses the information to address the group of one or more instances of one or more business objects, on which the application can perform one or more functions.
