As XML is considered as a standard to represent and exchange data on the web, there are many researches to develop applications based on XML Along with these trends, many researches are on going to develop the techniques on storing and searching XML documents But the data models in these researches mainly focus data-centric XML and cannot support document-centric XML fully A data model for document-centric XML document is proposed in this paper Using the proposed model, it is possible to represent the semantic and structural information of XML document fully And a algebra for the proposed model is also proposed as the foundation for query language and query processing
