Introduction

ISO 10303 STEP is an ISO standard.
ISO TC184/SC4 The ISO committee responsible for the development of STEP.
Practitioners: STEP is a collection of standards called Application Procols.
Researchers and developers: STEP is an important source of modelling and implementation methodologies.
CALS  STEP is related to the standard for Computer-aided Acquisition and Logistic Support.
IFC For the AEC industry a parallel industry standard IFC (Industry Foundation Classes) is being developed by the International Alliance for Interoperability (IAI).
BCCM Building Construction Core Model was being developed for the AEC industry.
Research institutes  Many of these institutes are active in STEP
European research projects  Many EU projects are related with STEP
XML  STEP and IFC standards are likely to be affected by the XML standard for document representation on the WWW.
