Hello everybody,
I've written a Spotlight Importer for my custom document format. The
document has an UTI, used by the Spotlight Importer.
Everything is fine, I can see my Metadata Fields correctly indexed by
Spotlight, I can see the right importer loaded (it is bundled into the
.app) when I run `mdimport -L`, except the Finder doesn't display the
fields I've said it to display.
Here is what the schema.xml file look like :
<?xml version="1.0" encoding="UTF-8"?>
<schema version="1.0"
xmlns="http://www.apple.com/metadata";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="
http://www.apple.com/metadatafile:///System/Library/Frameworks/CoreServices.framework/Frameworks/Metadata.framework/Resources/MetadataSchema.xsd
">
<attributes>
<attribute name="com_myDomain_myApp_myDocument_test"
multivalued="false" type="CFString" />
</attributes>
<types>
<type name="com.myDomain.myapp.mydocument">
<allattrs>
kMDItemTitle
kMDItemAuthors
kMDItemAlbum
com_myDomain_myApp_myDocument_test
</allattrs>
<displayattrs>
kMDItemTitle
kMDItemAuthors
kMDItemAlbum
com_myDomain_myApp_myDocument_test
</displayattrs>
</type>
</types>
</schema>
I wasn't able to validate this file syntax (but it seems right), my system
is lacking the `mdcheckschema` command, and I can't find it anywhere. Also
I thought that fields appearing in the `<displayattrs>` would have been
displayed by the Finder's Get Info pane.
The `schema.xml` file appears at the right place into the mdimporter
bundle. This is really annoying, since I use already defined fields, and
only one custom field. Apple's documentation doesn't tell anything on this
situation and I wasn't able to find an answer to my problem.
Does anybody know what to do to have those informations displayed by the
Finder's "More Info" section ?
Maybe someone can provide useful tips ?
Vince.
