  Rezumat:   XML is a popular data representation and exchange format over the web. Many articles propose di fferent conceptual models for XML design, but there is no standard format for conceptual design of XML data. Franceschet et al. (2013) demonstrate that nested schemas are globally more efficient than at ones. In this paper an FCA based representation of XML conceptual modeling is proposed. Entity-Relationship data model is used initially. A Relational FCA approach is given for the relations between entity sets. A mapping from Entity-Relationship model to a schema for XML in form of concept lattices are presented for relations of type one-to-one, one-to-many and many-to-many. The obtained concept lattices reflect these three di fferent relationship types, also the possibility of nested XML scheme design can be seen on the lattices.
