ISO/IEC 15944-4:2015提供了一组UML类图和概念解释，它们限定了开放式edi业务事务本体（OeBTO）。它解释了业务事务状态机（OeBTO的过程组件）的机制，以及OeBTO的（内部）约束组件（业务规则存储库）。 ISO/IEC 15944-4:2015阐述了ISO/IEC 15944-1中定义的独立贸易伙伴之间的合作。ISO/IEC 15944-4:2015适用于二元协作（买方和卖方）和中介协作（买方、卖方、第三方）- 党）。本文描述的本体特征仅为业务操作视图（BOV）提出了标准，即ISO/IEC 15944-1中定义的业务事务的业务方面。

ISO/IEC 15944-4:2015 provides a set of UML class diagrams and conceptual explanations that circumscribe the Open-edi Business Transaction Ontology (OeBTO). It explains the mechanics of a business transaction state machine, the procedural component of an OeBTO, and the (internal) constraint component of OeBTO, its repository for business rules. ISO/IEC 15944-4:2015 addresses collaborations among independent trading partners as defined in ISO/IEC 15944？1. ISO/IEC 15944-4:2015 applies to both binary collaborations (buyer and seller) and mediated collaborations (buyer, seller, third-party). The ontological features described herein propose standards only for the Business Operational View (BOV), that is, the business aspects of business transactions as they are defined in ISO/IEC 15944？1.
