This is an example Spotlight plugin (importer) that shows how to

import data from a package based file format.  In this case we

publish metadata for the note files saved by the application

NoteTaker.

The import parts of this importer are the changes made to the

Info.plist file.  First, it use the UTImportedTypeDeclarations

instead of UTExportedTypeDeclarations so that if NoteTaker

does declare its own UTI for its file format that it will not

override the one declared in the importer.

Next, the UTTypeConformsTo section shows how you should declare

a file format which is a package.  Getting the type hierarchy

correct is import for your files to display properly in the

Finder and Spotlight search results.

Last, the implementation of GetMetadataForFile() shows how you

can get the information out of a package using the Cocoa api's.
