# SKDocument

## Declaration

```

## Discussion

Discussion A document URL object is a generic location specification for a document. It is built from a document scheme, a parent document, and a document name. You can convert back and forth between document URL objects and CFURL objects using Search Kit’s SKDocumentCreateWithURL(_:) and SKDocumentCopyURL(_:) functions. To create a Search Kit document URL object, use SKDocumentCreateWithURL(_:) when you can provide a complete URL, or use SKDocumentCreate(_:_:_:) when you want to specify document location indirectly using a parent document URL object. For other operations on documents, see Working with Documents and Terms. If you create document URL objects with indirect locations using the SKDocumentCreate(_:_:_:) function, you can resolve the locations by assembling them piece by piece, starting with a document URL object and going up step by step, parent to parent.
