Patent number: 8140582Abstract: A method, system and computer program product for identifying one or more niche services to combine into a common service, wherein the niche service is a part of a service oriented architecture (SOA). The extensible markup language (XML) schema of the one or more niche services is aggregated into a combined XML schema, wherein the combined XML schema is the XML schema of the common service. A web services description language (WSDL) of the one or more niche services are aggregated to establish a combined WSDL, wherein the combined WSDL is the WSDL of the common service. The common service is generated from the combined XML schema and the combined WSDL. The combined WSDL, utilized to identify the combined service, comprises a service provider URL, one or more service operations, and combined XML schema. The combined XML schema is associated with a common service request and a common service response. When the XML schema of the niche service is not equal with the combined XML schema, mediation is invoked.Type: GrantFiled: October 7, 2008Date of Patent: March 20, 2012Assignee: International Business Machines CorporationInventors: David D. Chen, Douglas E. Griswold, Lance A. Walker

Patent number: 7991802Abstract: An exemplary feature is a method for using XML Schema based standards. The method consists of constructing a reduced schema for a specific interaction from a collection of reusable artifacts. The method further consists of publishing the reduced schema in a repository thereby allowing the reduced schema to be reused.Type: GrantFiled: July 30, 2008Date of Patent: August 2, 2011Assignee: International Business Machines CorporationInventors: David D. Chen, Ralph A. Hertlein, John W. Miller, William R. Wise, Jr.

Patent number: 5557746Abstract: A system and method for recording accounting times by an Agent in a network and retrieving the accounting times by the network Manager. Three types of data objects in each of the Agent's stored records are provided. Record Number is the sequence number of the record in the file. Recording time is an indication of the time the record was stored in the file since a certain point in time, such as after the Agent's clock began running. Record Type is the particular type of record stored. The Record Type can either be DATA representing normal accounting data or TIME representing time data used for correlating the Manager's and the Agent's time-keeping. Upon receipt of an accounting data record of type DATA, the manager uses the record's Recording time to help determine the point of time accorded to that event. The Manager then uses the previous record of type TIME to adjust the Recording time of the received accounting data record relative to the Manager's precise calendar time.Type: GrantFiled: September 20, 1993Date of Patent: September 17, 1996Assignee: International Business Machines CorporationInventors: David D.
