Methods, systems, and computer program products for converting an object of one type to an object of another type that allow for the runtime operation of the conversion process to be altered or customized. The conversion may occur within an extensible serialization engine that serializes, deserializes, and transforms objects of various types. The runtime operation of the serialization engine is altered by one or more extension routines that implement the desired customizations or extensions, without requiring replacement of other existing routines. Based on type information, identified for an initial object, the object is converted to an intermediate representation which permits runtime modification, including modification of object names, object types, and object data. The intermediate representation of the initial object is modified in accordance with extension routines that alter the runtime operation of the serialization engine, and the intermediate representation is converted to a final object and type.

XML schema types can be identified and compared for equivalence so as to avoid unnecessary and undesirable creation of multiple classes for equivalent schema types. XML schema types having the same name are identified and normalized according to a unified system for representing schema types. The step for normalizing schema types can include any writing and/or rewriting at least a portion of the schema types into a common unifying format so that they can be compared. Once the schema types have been normalized, they are then compared for equivalence. One technique for comparing the schema types is to create and compare hash numbers of all or only selected portions of the normalized schema types. Equivalent schema types can then be indexed to share a single class, thereby avoiding the creation of multiple classes for equivalent schema types.
