E-marketplaces provide a promising approach for the facilitation of business collaboration, transaction automation, and supply chain formation. The key challenge for the effective development of e-marketplaces is to understand their underlying business models and to align these business models with current software development models. However, most work on e-marketplaces has concentrated on solving specific problems, rather than providing reusable software development models. This paper proposes the application of the Domain Engineering approach for the development of tendering e-marketplace applications. This approach combines the analysis of the e-marketplace domain with a set of Domain Engineering models to support the development of tendering e-marketplace assets. The paper illustrates the use of the resulting assets in the development of tendering e-marketplace applications.
