The amount of Web data repositories has been increasing for several application domains. Ontologies and conceptual schemata are important in this context to provide a semantic understanding of this data, which is usually instantiated through XML documents. In order to contribute to the problem of XML document engineering for a data repository in a given domain, this paper proposes an approach for converting a conceptual schema to an XML schema. Specifically, it focuses on the conversion of an Extended Entity-Relationship (EER) schema to an XML logical schema that abstracts different XML implementation schemata. The conversion is based on a set of rules as well as a process that controls rules' execution to generate a schema in an XML logical model. Compared to related work, our approach considers all EER constructs to generate a suitable XML logical schema.
