Paper Abstract:
|
The schemas currently implemented as weIl XML documents available from the web hardly reflect the semantics of the data very little at aIl. As a result of this situation, it is still difficult to understand, question, modify, integrate, interconnect a relational data base or an XML document. Consequently we propose to annotate a relational schema or an XML document with semantic features in order to automatically recover a conceptual view. The annotation which we propose can be directly implemented with an RDBMS or described into a DTD. Such annotation can significantly facilitate the management and use of relational sources and XML documents. We give then the mapping rules to publish relational data in an XML document and to store an XML document into a relational data base. These rules preserve the annotation. |
