EXPRESS HL API


Explanation

General support an HDF5 API and tools for the product model language EXPRESS. EXPRESS is a data modeling language used for product model data. It has been very successful, and is accompanied by a format called STEP (standard for exchange of product data, a text-based format), in which express entities are instantiated. A number of organizations have used HDF5 as a binary companion to STEP. The most promising, from a general usage perspective, seems to be that of EuroSTEP and the European Union, with some participation by The HDF Group (with support from the National Archives and Records Administration). See the web site for information.
