  • Patent number: 7840934
    Abstract: A method and system for integrating workflow management systems with business-to-business interaction standards. An automatic business-to-business (B2B) template generator is provided for supporting workflow design. The B2B template generator automatically generates process templates and service templates based either on a description of a business-to-business interaction standard is received or a structured representation of the business-to-business interaction standard. When the (B2B) template generator receives the description of business-to-business interaction standard as the input, the (B2B) template generator first converts the description of the business-to-business interaction standard into a structured representation of the business-to-business interaction standard. At least process template is automatically generated based on the structured representation of the business-to-business interaction standard. The template (e.g.

  • Patent number: 7222334
    Abstract: An electronic services modeling tool for composite e-services and functionality, where a composite e-service is an e-service defined by composing other basic or composite e-services. Implementation of an e-service for composing e-services into a composite e-service. Characteristics of composite e-services and of their differences with respect to traditional workflow-like composition. Definition of a composition model suitable for e-services. Description of a prototype implementation, showing an approach that can be reused for implementing composition on top of any E-Services Platform. Providing composition functionality as an e-service, to be used not only by the owner of the ESP, but also by any designer-user. A specific type of e-service, meta-service, called Composition E-Service, allows the definition, execution, management, and monitoring of composite e-services.
