Perhaps you should file a feature request at developer.apple.com/
bugreporter.
In the meantime, you could save the compositions that users add to
your app into the Application Support folder for your application, and
load them from there.
Our line of reasoning is that users should not have a polluted
Repository. If every legacy composition was added to the repository
there would be no way to know whether it was an animation or an image
filter etc. Compositions will be updated as Leopard is adopted, and
then these compositions will have the proper tags as the Artist
intended.

Yes but the problem is the following.
The user of my application can download on the internet the
compositions he wants and then import
the qc file with my application.
After that my application use the composition to render it.
But the composition on the internet are not all created with the new
editor and doesn't have the protocol
setted.
If I copy theses qc file in the folder of the
QCCompositionRepository they don't have any protocol
and I can't filter the QCCompositions correctly.
My idea was to set the protocol and save the file before adding it
to the repository.
But if there is no solution with code, I can't use the repository
and copy the qc file
in another folder.

There isn't an API for this, you must go through the editor.
1.) Open a composition in the Quartz Composer application
2.) Choose Editor>Protocol Conformance
3.) Select which protocols you want.
4.) Save.

I try to copy some compositions in the Library/Composition folder
in the user folder in order to
use the QCCompositionRepository class.
I don't have found any method to add a composition to the
repository, but in the doc, it says
that the qc files are in the Library/Compositions folder at the
root or in the user folder path.
I try to copy some olds qc files in this folder, but they don't
have a protocol conformance because
they have been added in Leopard.
I want to update from my app the protocol conformance attribute of
the qc file, but I don't have found
any method to save the QC file after editing the attributes.
How can I do that ?
I want to :
1) Create a QCComposition object from a qc file
2) Editing the protocol conformance attribute of the QCComposition
object
3) Save the QC file
4) Copy the QC file to the /Library/Composition folder in the home
user folder.
Thanks
Christophe
