We are currently working on a Spotlight importer for our custom
data format.
Out file references another file on the file system, so we want to
get the metadata of the referenced file to include (at least part
of) in our returned metadata. So the following questions:
1.) Is there any API to directly call an importer for a specific
file to get its metadata.
2.) If no to #1 (which I don't believe is the right way to go), we
are creating a NSMetadataQuery to get the public metadata for the
specific file. We are creating an NSPredicate where
kMDItemPath == the/path/to/the/referenced/file
However this query always returns 0 results. However if we create
a query where
kMDItemDisplayName == NameOfReferencedFile
we get (at least) one result, and in that result the kMDItemPath
returns the full & correct path to the file.
Anyone know why the query where "kMDItemPath == the/path/to/the/
referenced/file" is unable to locate the file?
This currently doesn't work if you know the path to the file use use
the function
MD_EXPORT MDItemRef MDItemCreate(CFAllocatorRef allocator,
CFStringRef path) MD_AVAIL;
to get the MDItemRef
Seems like you can't do the equivalent with the NSMetadata calls.
(This testing is all done in a standalone application, not in an
importer).
Is this a bug, or am I off base somewhere?
Thanks.
