1. A method for mapping one or more source schemas to at least one target schema, comprising:

  • obtaining said one or more source schemas; and

    mapping one or more edges in said one or more source schemas to one or more paths in said at least one target schema, wherein said mapping does not violate one or more prefix-free conditions and one or more path-type conditions, wherein said one or more prefix-free conditions require that for any two edges (A, B) and (A, B′

    ) in said one or more source schemas, the path (A,B) in said one or more source schemas is not a prefix of the path (A,B) in said at least one target schema and said one or more path-type conditions requires that each edge and a corresponding path to each edge in said one or more source schemas have a same type.
