<p>We discussed the potential inclusion of QIF in the work program
of WG15. <br>
</p>
<p>The O3 project used three standards: STEP, MTConnect and QIF to
enable the integrated measurement of machined parts during
manufacturing. <br>
</p>
<p>Each standard has its own advantages and capabilities.</p>
<ul>
<li> STEP excels at product modeling which requires a large
investment and needs stability to maintain value and secure long
term archiving.</li>
<li>MTConnect excels at process monitoring which requires real
time communication and a data model that is easy to process.<br>
</li>
<li>QIF excels at reporting which requires a rich, flexible data
model that can explain the reasons for a report.</li>
</ul>
<p> </p>
<p>Together the standards can define a digital thread for
manufacturing, but separately they need additional capabilities.
Efforts are being made to extend these capabilities but for
example, a technology that is good at reporting run time process
changes may not be good for the long term archiving of product
model data and vice versa.</p>
<p> The O3 project suggests there is an alternative which is to have
the three standards cooperate within a federated framework. In
such a framework a new edition of Part 28 might be used to
communicate changes between manufacturing systems. Such a Part 28
could be modeled after MTConnect and used to communicate
information updates between executing manufacturing systems. The
architecture is illustrated by the diagram below and the O3
project has made a video describing how it might work.</p>
