|{{Func|db:dir|$db as xs:string, $path as xs:string|element()*}}
|-
| '''Summary'''
|Returns meta data on all directories and resources of the database {{Code|$db}} in the specified directory {{Code|$path}}. Two types of elements are returned:
* {{Code|resource}} represents a resource. The element value is the directory path; content type, modification date, raw flag (which indicates if the resource is binary or XML), and size of the resource are returned as attributes.
* {{Code|dir}} represents a directory. The element value is the directory path; the modification date is returned as attribute.
Please note that directories are not stored in BaseX. Instead, they result implicitly from the paths of stored resources.
