XML interoperability standards for seamless communication: An analysis of industry-neutral and domain-specific initiatives

Attaining seamless interoperability among heterogeneous communication systems and technologies remains a great challenge in todays’ networked world. Real time information exchange among heterogeneous and geographically distributed systems is required to support the execution of complex e-business scenarios supported by cross-organizational business processes. XML emerged as a foundation for performing e-business, receiving an increasing adoption in the new market economies. Several interoperability standards emerged, which provide specifications on performing business-to-business e-business, what information to share, when and how. The aim of this article is to present an up-to-date review of current XML-based industry-neutral and domain-specific standardization initiatives towards seamless communication, discussing their commonalities and differences, and highlighting directions for further research and development work. An overview of the main standards’ elements is also made, analyzing how different initiatives address them. As numerous standardization initiatives are quickly emerging and changing, it is not easy to understand them. By analyzing the most commonly referred XML-based standards for interoperability, this article has two main contributions. First, it provides an up-to-date review of the most relevant industry-neutral and domain-specific standardization initiatives aiming at achieving seamless interoperability among communication systems. Second, by comparing these initiatives, a set of recommendations is advanced towards improving further interoperability developments, offering a unique niche for researchers, practitioners and developers to make significant contributions
