An Introduction to Topic Maps about an ISO XML standard for mapping real-world resources to abstract concepts
Value-Driven Architecture: Linking Product Strategy with Architecture about how value models, as opposed to business requirements, influence application architecture
Process and Criteria for Evaluating Services-Based Integration Technologies about the evaluation of technologies for integrating service-oriented systems
Service-Oriented, Distributed, High-Performance Computing about a clustering/grid strategy for building HPC systems over the Internet
Planes, Trains and Automobiles: Choosing Alternate Transports for Web Services about using message queues or an HTTP/SMTP combination for SOA instead of straight HTTP.
Every article is about 15 printed pages.
