In the advent of current development in PDM (Product Data Management) System, the STEPlib (Standard for the Exchange of Product Model Data Library) of ISO-10303 standard written in Gellish English has been conceived and it's archive of the volume is so immensely extensive in the view of Taxonomy for Product Data Model. Based on RDMS (Relational Database Management System such as Oracle) and XML (Extensible Markup Language) for Web interface, framework is kept as compatible as that of RDBMS and XML applications and the semantics among the terms like UID (Gellish Unique Identifier) are defined unambiguously in the STEPlib database. As of the hierarchy for the tables of data stored within the database, SQL (Structured Query Language) acts like a backyard storage, of which data format is linked and interfaced with XML web transactions. Taking into account of the inference in query process for this STEPlib with SQL or XML, user's perception for this Thesaurus framework is hard to comprehend in the middle of the navigation through the Taxonomy for Product Data Model. In this sense, Expert support is indispensable and should be implemented at the user interface for query operation.
