ISO/TS 10303-26:2011(E)

Introduction

ISO 10303 is an International Standard for the computer-interpretable representation of product information and for the exchange of product data. The objective is to provide a neutral mechanism capable of describing products throughout their life cycle. This mechanism is suitable not only for neutral file exchange, but also as a basis for implementing and sharing product databases, and as a basis for archiving.

This part of ISO 10303 is a member of the implementation methods series. This part of ISO 10303 specifies a binding of the EXPRESS language into the Hierarchical Data Format Version 5 (HDF5).

The Hierarchical Data Format Version 5 (HDF5) is a product of The HDF Group, a spin off from the National Center for Supercomputing Applications (NCSA) at the University of Illinois at Urbana-Champaign. The HDF software includes I/O libraries and tools for analyzing, visualizing, and converting scientific data.

This part of ISO 10303 specifies a mapping of EXPRESS-driven data instances to the HDF5 file format. This part of ISO 10303 does not map all EXPRESS modeling language constructs to HDF5. HDF5 is not a modeling language, however an HDF5 file does include the data types of the data instances it contains.

Readers of this part of ISO 10303 need to have detailed knowledge of the concepts of EXPRESS language (see ISO 10303-11) and HDF5. Programming examples are provided using the HDF5 application programming interface.
