UserNotAuthorizedException,
PropertyServerException

Creates a new folder asset that is identified as a data asset. This means the files and sub-folders within it collectively make up the contents of the data asset. As with other types of file-based asset, links are made to the folder structure implied in the path name. If the folder structure is not catalogued already, this is created automatically using the createFolderStructureInCatalog() method. For example, a pathName of "one/two/three/MyDataFolder" potentially creates 3 new folder assets, one called "one", the next called "one/two" and the last one called "one/two/three" plus a DataFolder asset called "one/two/three/MyDataFolder".

Parameters:

userId - calling user

displayName - display name for the file in the catalog

description - description of the file in the catalog

pathName - pathname of the data folder

Returns:

list of GUIDs from the top level to the root of the pathname
