Resolved How can I add customized attributes to my files?

I wish to have customized attributes for some of my files, just like how they have permissions, creation date, and so on.

It seems that HFS+ and Spotlight supports this, and I've looked at various classes like MDItem, but the documentation on Dev Center leads me around in circles, and I get the idea that a lot of cross-references are missing. For someone new to all that material it's like navigating a maze.

It's OK if Spotlight indexing is required, but it's necessary that the attributes persist when I copy the files around, and that this can be done programmatically without having to install plugins or any kind of additional system components.

Any pointers?

Thanks.

 

This is exactly what I was looking for. Thanks so much for your help.
