Apparatus, methods and computer programs provided for metering and accounting in a commercial e-services infrastructure address the requirement for handling composite services in which higher-level services are built using simpler underlying services, each of which may be autonomously owned and operated. Metering records for each service underlying a composite service are correlated by a process associated with the composite service, and then sent to an accounting service where they can be aggregated. The correlation is performed in a distributed manner with correlated usage data provided on a per-request basis. Accounting services can take account of the usage and charges associated with the underlying services to provide accounting and billing on a per-request basis or per customer-provider pair for a billing period.

The invention claimed is: 1. A computer program storage medium readable by a computer, tangibly embodying a program of instructions executable by said computer to perform a method for metering usage of composite services which are accessed via a network, the method comprising: requesting a composite service by a user program, wherein said composite service comprises service composition pairs, in which a higher level service invokes a lower level service and a charging model of said higher level service determines said charging model of a service composition pair, said composition pairs comprising: a transaction service over a resource-centric service, in which metering information for a lower resource-centric service, including resource consumption metrics, and for a higher transaction service, including transaction usage metrics, is charged per transaction; a composite resource-centric service, in which metering information for a lower resource-centric service, including lower resource consumption metrics, and for a higher resource-centric service, is charged for composite resource consumption; a composite transactional service, in which metering information for a lower transactional service, including lower transaction usage metrics, and for a higher transaction service, including higher transaction usage metrics, is charged for composite transaction usage; and a resource-centric over a transaction service, in which metering information for a lower transaction service, including lower transaction usage metrics, and for a higher resource-centric service, including higher resource consumption metrics, is charged for resource consumption; generating partial metering records for all service requested by said composite service, said partial metering records corresponding to each requested service, including identities of each higher and lower service of a service composition pair, and an appropriate charging model; sending said partial metering records to an accounting service; and correlating said partial metering records, by said accounting service, based on a hierarchical-tree of said service composition pairs, to create a complete metering record of said requested composite service. 2. The computer program storage medium of claim 1, wherein said method further comprises creating an accounting record that identifies a customer that requested said composite service and a provider of said composite service. 3. The computer program storage medium of claim 2, wherein said method further comprises applying a pricing policy to said accounting record to generate an invoice. 4. The computer program storage medium of claim 2, wherein said method further comprises aggregating service usage accounting data on a per customer and per provider basis to generate aggregate accounting records for a billing period. 5. The computer program storage medium of claim 1, wherein said method further comprises marking records of metered usage data as complete if any of the following conditions is satisfied: a set of requested component services is empty; and metered usage data is available for all of the set of requested component services and has been successfully correlated to generate composite service usage data, otherwise not marking said records as complete. 6. The computer program storage medium of claim 1, wherein said method further comprises registering said composite service with a respective accounting service, the step of registering comprising providing the accounting service with an identification of at least one charging model supported by the composite service. 7. The computer program storage medium of claim 1, wherein said method further comprises the accounting service determining a charging model for the composite service in accordance with charging models supported by the composite service. 8. The computer program storage medium of claim 1, wherein said method further comprises generating charging data from said composite service usage data and said charging models.
