Abstract: The present invention provides a process and system for matching buyers and sellers of either goods or services, or goods and services for a project. The invention enables a buyer to specify a project in terms of physical, functional, temporal, financial, and transactional parameters that can be automatically converted, by the present invention, into at least one request for either goods or services, or goods and services to perform work related to the project. The requests are suitably provided to at least one seller. Upon receiving a request, the seller may submit a response to the request, as desired. The invention provides a forum for the negotiation of any agreements and the formation of contracts to provide the requested, or alternative goods or services, or goods and services, as well as reconciliation of purchase orders, actual field costs, and invoices.

Abstract: A method and system for enhancing a workflow system by providing supportive information for a project is disclosed. A purchase order relating to at least one request for at least one good, at least one service, and combinations thereof relating to the project is received from a first user. An actual data to complete a portion of the project is received from a second user in response to the purchase order. An invoice is received from the second user upon completion of the portion of the project. The purchase order, actual data, and the invoice are compared to determine a discrepancy between the purchase order, actual data, and the invoice. A proposed reconciliation from the first user or the second user is received in response to an electronic notification of the discrepancy. An approval or disapproval of the proposed reconciliation is received from the first user or the second user.

Abstract: In a complex workflow environment, a data-type-definition (DTD) schema drives a dynamic business component instantiation and execution framework that integrates documents with data and information created by various applications, potentially operating on several different platforms, enabling complex workflow and collaboration to occur over a communication network such as the Internet. The DTD execution language is preferably an industry specific XML-based tag set that defines business component instantiation, execution, input and output parameters, workflow, user profile, and collaboration specifications for a given task or data in a complex workflow process. Business and data processing components available on systems both within and outside the complex workflow system are called upon to provide the processing, interpretation, and transformation functions for the complex workflow system.

Abstract: The present invention provides a process and a system for matching buyers and sellers of goods and/or services for a project. The invention enables a buyer to specify a project in terms of physical, functional, temporal, financial, and/or transactional parameters that are then automatically converted, by the present invention, into at least one request for goods/services perform work related to the project. The requests are suitably provided to at least one seller, who may be pre-identified by the buyer as a preferred seller. The requests may be accompanied by supporting information or reference links to sources of such supporting information. Upon receiving a request, the seller may submit a response to the request, as desired. The seller's response may likewise include attachments with information supporting the proposal, or reference links to such information in other sources.
