Scenario-Based Generation of Digital Library Services

Abstract

(Abstract)With the enormous amount of information being created digitally or converted to digital formats and made available through Digital Libraries (DLs), there is a strong demand for building tailored DL services to attend the preferences and needs of diverse targeted communities. However, construction and adaptation of such services takes significant effort when not assisted by methodologies, tools, and environments that support the complete life cycle of DL development, including requirements gathering, conceptual modeling, rapid prototyping, and code generation/reuse. With current systems, these activities are only partially supported, generally in an uncorrelated way that may lead to inconsistencies and incompleteness. Moreover, such existing approaches are not buttressed by comprehensive and formal foundations and theories. To address these issues 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) an 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, and 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; and 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.Thanks is given to the AmericanSouth.org project funded by the Mellon Foundation.iii

A formal approach for the specification of digital complex objects

“…Tools based on the 5S framework have been built to facilitate DL development, mainly in the tasks of requirements gathering, conceptual modeling, and DL building [14], as shown in Figure 2. The main objective is to tailor DL services, exploring the metamodel and respective applications.…”

Integration of complex archeology digital libraries: An ETANA-DL experience

“…3). 5SGraph [11,12] supports analysis and specification, while 5SGen [13] melds together suitable components from a large software pool to yield a running system. To semi-automatically build an integrated DL, we extend this approach and develop the 5SSuite tool to cover the process of union DL generation, including requirements gathering (see Fig.…”

Streams, structures, spaces, scenarios, societies (5s)

“…Finally, searching and browsing services were taken for granted due to the powerful MARIAN digital library API. More work is necessary to investigate the process of generating Kelapure et al [2003]. Nevertheless, it seems clear that 5S has intuitive appeal and practical application.…”
