3. The method of claim 1 , wherein the dynamic substitution provides a standardized view of non-native types to the metadata reader.
1. At a computer system including at least one processor and a memory, in a computer networking environment including a plurality of computing systems, a computer-implemented method for efficiently modifying object model type references, the method comprising: an act of instantiating a type reference table configured to receive type definition requests and provide appropriate type definitions in response using one or more type reference tokens stored in a metadata file readable by a metadata reader, the metadata file including native and non-native encodings of the same metadata within the metadata file; an act of the instantiated type reference table receiving a type definition request for a specified type from a type requester; an act of implementing type reference tokens in the metadata of the type reference table to dynamically substitute one or more types for the metadata reader based on which type was requested and which type is appropriate for the current consumer of the metadata reader; and an act of providing the requested type definition to the type requester based on the dynamically substituted types provided by the type reference tokens in the metadata.
