4 Searchable metadata attributes

4.1 HELIOS specific metadata attributes

HELAnnotationStatus
 

The status of a WebShare annotation. (annotationindexer)

This attribute can take the values:
0 = No status
1 = Status OK
2 = Status rejected

4.2 Common metadata attributes

List of attribute keys, including their aliases, that are common to all file types. Some attributes are only set by specific modules:

Important:

The listed aliases can replace the metadata attributes in a simple search request. In a Spotlight search on OS X, the Finder “translates” these aliases to the corresponding metadata attributes. On OS X, the aliases depend on the specified OS language, so that the alias names stated here are only valid if the Finder is set to English! For other OS languages refer to the Apple Help item “Specifying criteria in the Spotlight search field”.

Please note that attribute names are case-sensitive!
