The goal of this minitrack is to explore the challenges, issues and opportunities related to E-Government architecture, infrastructure and integration services. We promote a diversity of research methods to study the challenges of this multifaceted discipline focusing on various aspects of architecture, infrastructure, and interoperability at decentralized and centralized levels of government. Possible topics of theoretic, applied, field and empirical research include, but are not limited to:

• Development, implementation, maintenance, and overhaul of e-Government architecture, infrastructure and integration services
• Strategies and innovative approaches to enhancing interoperability (technical, semantic, organizational, managerial)
• Architecture and infrastructure planning, alignment and interoperability strategies
• Design and application of e-Government architectures and infrastructures for interoperability in public administration
• The integration of IS (legacy and EGIS) to support inter-organizational aspects of e-Government
• Service-oriented architectures, web services, web service orchestration for public administration
• Interoperability standards and frameworks
• Best practices and case studies at all levels of government, including local and transnational government
• Longitudinal studies that span over generations of e-Government implementations
