CMAP: Geração e representação de equivalências entre documentos XML, ontologia e modelo relacional

Abstract

Several applications require the storage of XML data, which may come from many sources. The freedom on XML data structuring makes possible that documents belonging to the same application domain may have different structures. In this context, the use of a relational database to manage the information contained in these documents can be a viable alternative, since the information could be stored in one place. The realization of such process could be done by integrating the XML documents and creating a unified model that represent them. This integration process can be accomplished with the help of ontologies because they focus on the semantic content. After the unification, a model of relational database can be generated representing all the structures of the XML documents. Finally, the information can then be migrated to the generated database and retrieved through SQL queries. In this context, the general objective of this work is to generate a document that allows mapping the concepts originally found in the XML files to their equivalent in the generated relational model. This document will be created from the XML input files, the ontology used in the overall process, and the XML representation of the generated relational model.
