Adding Aliases & Society Identifiers
When importing income files to Curve, we will aim to map this income to the correct Work in your catalogue using the Identifier or ISWC as a reference. If the values found in the income file are an exact match with the Main Identifier or ISWC field in your Work, the income will automatically map to this Work.
It is of course very common for societies or sub-publishers to account income to your with their own internal song Identifiers. These alternative Identifiers can be stored as a Society Identifier or Alias on the Work. The one difference between Society Identifiers and Aliases is that Society Identifiers will only be used by Curve when the importing Template Source is an exact match to that of the Identifier Source. Whereas an Alias can be used to map income to Works at all times, regardless of the Template Source. Most commonly, you will be adding Society Identifiers using the Unmapped page.
In the below example, the identifier TB123452 will only be used when the Template Source is PRS, whereas 54126162 can be used for income from any Source.
The Template Source
The Template Source is thus an important field in your Templates. When creating new Templates, it is best practice to remain consistent in your Template Source choice. When updating the Template Source from PRS to Performance Rights Organisation, those Society Identifiers mapped to PRS would no longer be in use.
As a pro tip, if multiple Societies use the same identifiers, it is best to store their separate Templates under the same Template Source. In the UK for example, both PRS and MCPS use the same identifiers, and using the Template Source PRS for both templates will make sure we would only have to map unknown identifiers once, rather than once per Template Source.
