CIM Issues #5014

Updated by Todd Viegut 5 months ago

Oslo 14 June 2023 
 Considering that we expect to have models that include distribution and transmission grids, the recommendation is to remove multipliers in the profiles. It will be a breaking change. 

 There are 3 ways how to implement this: 

 1) delete .multiplier from the canonical UML. This implies that the multiplier is 1. This needs discussion with other TFs 
 2) fix the .multiplier to "none" in the canonical UML. This means that the multiplier is 1. This needs discussion with other TFs 
 3) fix the .multiplier to "none" in the profile, which means we need to pay attention when creating profiles so that all profiles are consistent. The advantage of this option is that there could be different approaches between different TFs 

 Preferred option is option 1, but due to 61850 harmonization perhaps option 2 is better. 
 TF13 may implement option 3 first. 

 This will not apply to hours, minutes, seconds 

 An email will need to be sent to WG13 to check the support for this agreement. 


 TF13, call 12-Jul-2023: 
 - Agreed to apply option 3 for all TF13 profiles for CIM18  
 - Before closing the issue make sure there is a joint issue to inform other TFs 


 TF13 call on 11-Oct-2023: 
 Final discussion and decisions to close the issue and leave the remaining attributes with the expectation that if there’s an issue or they are not needed someone will raise this.
