A method and computer system are described for conducting commercial transactions. An enhanced type of XML schema may be used which supports integrity constraints and polymorphism. Schemas are identified by the use of Uniform Resource Names. XML processors residing on transaction servers or trading partner servers parse document instances by retrieving the URNs corresponding to the schemas used to interpret the document. The URNs are converted to location-dependent URIs in order to locate the schemas. URNs are resolved to location-dependent URIs by use of the LDAP protocol. URNs may be converted to LDAP URLs which are used to search LDAP compliant directories. The directories serve as registries for the URI values corresponding to the URNs.

An aspect of the present invention includes a protocol for conveying data during an e-commerce session with a polymorphic response, comprising initiating a session with a message from a buyer application to a broker application and a session identifier assigned by the broker application; conducting the session between the buyer application and a supplier application; and concluding the session with a additional message which includes a schema identifier for the additional message, resolvable in a context of a system identifier; and a polymorphic response comprising a type and a version, wherein the polymorphic response includes additional data elements corresponding to values assigned to the type and version.

An object oriented system platform for a telecommunication system that provides subscriber services includes an upper layer containing applications in the form of base and supplementary functions providing base and supplementary services. This layer is implemented with base objects and extension objects. The base objects are object types implementing functions which may need extension in the future, each object type being designed for a particular task which can be performed with a minimum of coordination with other base objects. The extension objects are object types implementing extension functions which form extensions to the base functions and make it possible to add new services and modify and extend existing services without changing the software of a system that has already been implemented and supplied.
