API Reference > imodeljs-backend > iModels > IModelTransformOptions > noProvenance noProvenance noProvenance: undefined | boolean Set to true if IModelTransformer should not record its provenance. Provenance tracks a target element back to its corresponding source element and is essential for IModelTransformer.processChanges to work properly. Turning off IModelTransformer provenance is really only relevant for producing snapshots or another one time transformations. note See the IModelTransformOptions.includeSourceProvenance option for determining whether existing source provenance is cloned into the target. note The default is false which means that new IModelTransformer provenance will be recorded.
