The additional requirement imposed on any "neutral data format" such as STEP (Standard for the Exchange of Product data), has been a Web-enabled data representation. STEP allows dynamic sharing of data between different systems with the standard data accessing interfaces. A method for STEP and XML to be combined in presenting product information was studied. EXPRESS language (i.e. SCHEMA) is used for defining the data structure and DTD is used for XML transactions and presentations. Technologies on integrating STEP with XML have been discussed. A prototype system has been developed making use of STEP and XML as the data modelling and presentation tools.
