Methodological Questions How can tools and techniques best be applied? Which languages and tools should be used in which circumstances. and in which order What about issues of quality control and resource management? Many of these questions for the semantic Web have been studied in other contexts E.g. software engineering, object-oriented design and knowledge engineering 3 Chapter 7 A Semantic Web primer
