Examining Mac OS X 10.4's Spotlight
Ton writes "Apple has published a discussion of Spotlight, the radical systemwide search technology that will be part of Mac OS X 10.4 'Tiger'. The really interesting part is that metadata will be playing a big role in Spotlight while just a few years ago people were afraid metadata in Mac OS X was going the way of the dodo."
Anyone who has used the instantly updated searches in Mail.app or iTunes will have a feel for how useful a system-wide approach could be. However I too am concerned about resource usage. I think I'll wait and see how big the metadata index tends to get and how big the CPU/memory hit is.
I believe though that the indexing is done during saves, so you'll not notice a general system slow down. What you will notice is a slow down on file saves.
From reading the article, I think Hans Reiser has been right about the need for reiser4 on mainstream linux.
He saw all this stuff comming from way back. If you read the LKML, you will remember that he warned us.
Its a pity no one listens to him.
I read about beagle for linux it seems to be very similar in functionality. http://www.gnome.org/projects/beagle/

Coming from a WindowsXP background, some things Ive noticed so far:
- Clicking the 'X' doesnt actually close the application. This annoyed me to start with, but ive slowly gotton used to it.
- Having to select the application window before I can quit it using the application menu. Or I have to right click on the dock icon to quit. Annoying still.
- Love the dock. Its just
..... right.
- Most of the file system is hidden from you, which I like. Put my data where I want it and ignore the rest.
- The ability to access the underlying BSD OS easily. Love it.
- Everything looks and feels 'polished'. THats what I always hated about KDE/Gnome when I tried them, the features were there, but noone had taken the time to step back and polish the entire thing off so it all looks and feels together.
- Every time I boot the Mac, my TFT display is 'wavey' until i have the monitor do an autoadjust. Dont really know whoes fault this is, tho its fine under windows and linux.
So, final conclusion? I love it, so much that I have already placed an order for a G5 Imac. And in the meantime, Ive purchased a G4 upgrade for this little baby, just to help it alongUnless you used BeOS in the past!
This really is a big deal, much bigger than Microsoft's feeble attempts at full text search, or Google's desktop search. In many way's this much, much more useful than full-text search, especially for developers.
At home I have about 6,000 MP3s, a 1000 photos, 500 scientific articles in PDF format and hundreds of words files that I need to juggle. Each one has its own metadata database, and none of them are updated in real time.
Databases:
MP3 - WinAmp & AudioTron
Photos - Photoshop
PDFs - Acrobat Indexer
Word files - MS Indexer
That doesn't include any of the other data that is stored completely databases and would have been easier to store in the file system - like email, guitar tab files and god knows what else.
A properly implemented global meta-data store (that works at the filesystem level, not as an iterative service) profoundly changes how one uses the system, making sorting and finding data actually almost pleasurable.

I am the poster and the link was included in the post. Actually, the whole post was about the specific link to the Apple Developer site. Why the editors removed that link is absolutely beyond me...
