## Remarks

Shaped after [ICatalogAttribute](https://www.gooddata.ai/docs/gooddata-ui/latest/api-reference/sdk-model/sdk-model.icatalogattribute/index.md) so it can be listed and dragged among normal attributes; `defaultDisplayForm` is the fabricated display form of the computed attribute (see [IComputedAttributeMetadataObject](https://www.gooddata.ai/docs/gooddata-ui/latest/api-reference/sdk-model/sdk-model.icomputedattributemetadataobject/index.md)).
