Scenario-Based Generation of Digital Library Services

We describe the development, implementation, and deployment of a new generic digital library generator yielding implementations of digital library services from models of DL “societies” and “scenarios”. The distinct aspects of our solution are: 1) approach based on a formal, theoretical framework; 2) use of state-of-the-art database and software engineering techniques such as domain-specific declarative languages, scenario synthesis, componentized and model driven architectures; 3) analysis centered on scenario-based design and DL societal relationships; 4) automatic transformations and mappings from scenarios to workflow designs and from these to Java implementations, 5) special attention paid to issues of simplicity of implementation, modularity, reusability, and extensibility. We demonstrate the feasibility of the approach through a number of examples.
