PI Asset Framework Units of Measure: Any Custom Libraries Available?

James.Aylard

PI Asset Framework includes a reasonably good default selection of units of measure, but compared to the variety of engineering units in my PI data archive and the UOMs these represent, AF's list is limited. I know how to create custom UOMs, and have made several. But I got to wondering: instead of laboring to reinvent an already-existing wheel, is anyone aware of an open-source library of custom UOMs that can be imported into AF? My searches turned up nothing.

    Rick, that sounds about right. But done with care, it seems that values imported from an open-source, community-evaluated database would still be a better option that having to come up with UOMs from scratch. I think the GUID aspect would be resolved by unchecking the "Preserve Unique IDs" checkbox upon file import? Not completely certain, but that is how it appears to me. But I understand the points you raise around unique naming. I can see value in avoiding duplicate abbreviations for different UOMs, but I can also understand where that creates problems when the standard abbreviations are the same for two different units of measure. In that case, adding some very brief parenthetical addition to one or both UOM abbreviations might help, but would not be ideal.
