Abstract: A method and apparatus for creating a schema definition from a language-specific metamodel of a data structure written in a legacy computer language involves walking through the nodes of the metamodel, and creating corresponding schema element objects in a schema tree that is serialized to create the schema definition. The creation of the schema element objects follows rules, and permits the definition of nested data structures having conjunctive-type and disjunctive-type membership.
