A Rule-Based Conversion of a DTD to a Conceptual Schema semantically rich representation of an XML source. The core of the process is a set of . that consider the DTD structure and heuristics related to default semantic interpretations on such structure in order to generate the corresponding concepts in the canonical conceptual schema.

Semantic Data Modeling Using XML Schemasthe Entity-Relationship (ER) model. We especially focus on three data modeling capabilities of .: (a) the ability to represent ., (b) the ability to represent a set of semantically equivalent but structurally different types as “one” type using the closure properties, and (c) the ability to represent ..

Coping with Inconsistent Constraint Specificationsfour strategies towards conflict resolution: (1) determination ofs uperfluous object types, (2) incremental consistency checking, (3) detection ofmi nimal inconsistent subsets, (4) constraint correction via feedback arc elimination, and apply them to constraint sets containing cardinality constraints and key dependencies.

A Semantic Approach to XML-based Data Integrationema. The mapping from each individual DTD into the common schema is used to automatically generate wrappers for XML documents, which conform to a given DTD. These wrappers are used to populate the common conceptual schema thereby achieving data integration for XML documents.
