Reference Data - overview

latest update: 2018-01-14    

Introduction

ISO 15926 is modeled in a data-driven fashion, using templates that have "Roles", and where those Roles make reference to the URI of objects that have been declared as instances of the Part 2 entity types. Some of these instances are of global interest and some of local interest. The formers are stored in the ISO 15926 Reference Data Library, the latters in local extensions of same.

Typical Code (without most meta data)

Note that the RDL is not yet flawless and never complete. This is Work-In-Progress.

In total the RDL has 15464 active classes now.

Some of these contain a small set of classes, as they were required on projects, and others, such as the one from ASME, contain many classes.

DISCLAIMER - In any cases where the definition of a class is different from the original standard, the latter prevails.
