ISO 15926-7 is a not yet approved part of ISO 15926, an International Standard for the representation of process plant life-cycle information. Part 7 defines Implementation methods for the integration of distributed systems – Template Methodology
What does that mean ?
This is actually one of the most important parts when it comes to implementing ISO 15926. While Part 2 describes the limited list of terms that can be used to describe our requirements, Part 7 describes how these can be used in a useful way (or at least more easily understood by Engineers).
If Part 2 was a dictionary, this is great when we want to look up a single word. However, in general terms we want to be able to work with much more complex phrases.
Therefore Part 7 describes how these phrases can be used.
Templates such as
I want to record the maximum allowable working pressure and minimum allowable working pressure against a vessel which will be identified by a tag number.
Which is hopefully readable by every engineer.
Now imagine if this was described in Part 2 terms
There will be a relationship for a SinglePropertyDimension which will have a Scale of the class Pressure which will be classified as MaximumAllowableWorkingPressure and a relationship for a SinglePropertyDimension which will have a scale of the class Pressure which will be Classified as MinimumAllowableWorkingPressure between the ClassOfIdentification with a RepresentationForm of TEXT which is Classified as the ClassifiedIdentifier such that myVesselTemplate(tagNo, MinAllowPressuure, MaxAllowPressure)
Yes can you believe that they mean the same thing … which would you prefer to use and which is easier to understand.
Is this available online ?
Yes, the Templates can be found by searching the iRing User Group sand box for Templates
Will ISO 15926 Part 7 change ?
No, Part 7 as defintion of how to create Templates and their role will not change. Apendices A, B, C describe the Proto Templates which may over time be enhanced or modified, but should describe a solid foundation. The templates that you use in your project will be similar to the proto templates, but will generally be specific to your organisation or project .
