Introduction

This is the original application used by us for setting up the model of ISO 15926-2.
This standard reached IS (International Standard) status on December 15th, 2003, and still is valid as published then.

During the years we found something missing, and some things which require a change. But since the mills of ISO turn slowly, this hasn't been remedied yet.
See the topics Extended Data Model and Part 2 Cheat Sheet, where in the latter the required changes have been marked V2.0.

These additions and changes have, for the interim, been formalized in the lci extension (e.g. ClassOfMatter that becomes the superclass of all material types) of the RDL - Reference Data Library (http://data.15926.org/rdl/).
