Electronic business demands from production companies to collaborate with customers, suppliers and end users and start electronic manufacturing. To achieve this goal companies have to integrate their subsystems (Application to Application-A2A) and they have to collaborate with their business partners (Business to Business - B2B). For this purpose models and unique standards for integration are necessary. In this paper, ebXML and OAGI specifications have been used to present metamodel process by UML class diagram and standardized model of document Working Order for technological process in the form of OAGI BOD XML document. Based on it, from an example, model of techonogical process is presented by activity diagram (DA) in XML form and an appearance of document Working Order. Just as well, rules of transformation DA to XML are presented.
