RESUMO

Digital libraries are advanced and complex information systems that store, aggregate, and manage correlated information. These systems are used by specific communities to access digital objects of interest. Due to the creation of huge collections of heterogeneous data (in terms of type and format), some of these data are organized in digital complex objects, in the sense that they are composed by other digital objects. Since specification and implementation of digital libraries are decisive tasks to achieve an effective management of documents, specific software tools have been created to help and facilitate the specification and implementation of digital libraries. However, few existing tools used to model digital libraries allow the specification of complex objects. Besides, this kind of complex data make more difficult the tasks of specification, modeling, and reusing of complex objects. The objective of this dissertation was to propose a digital library metamodel in order to specify instances of digital libraries that manage complex objects. The new metamodel was included in the 5SGraph tool. 5SGraph is a software tool based on the 5S theory (Streams, Structures, Spaces, Scenarios, and Societies) and provides a visual environment for the formal specification of digital libraries. The new metamodel was validated through: case studies, an evaluation with potential users, and the implementation of a digital library prototype containing legal documents. According to the results, the extended 5SGraph tool can be used to specify digital libraries of complex objects. The main contributions of this work are: the characterization of legal documents as complex objects; the specification of a metamodel to be used in the specification of digital libraries of complex objects; the implementation of a metamodel in the 5SGraph tool, making the tool capable of specifying digital libraries of complex objects; the presentation of some case studies using the 5SGraph tool to specify complex objects of digital libraries; validation of the new metamodel in the 5SGraph with potential users; and the specification and implementation of a digital library prototype containing complex objects related to legal documents.
