Meaning of space URI of qualified name

[cesco75]

If I want to make a Lucene Path search in the subfolder of my user home I use the following expression:

PATH:"/app:company_home/app:user_homes/sys:cesco/cmrivato/*"

sys: prefix stands for {http://www.alfresco.org/model/system/1.0}, cm: stands for {http://www.alfresco.org/model/content/1.0}

All the elements are of type cm:folder so I expect every folder name should be prepended by cm:

There is a general rulo for the use of app, sys and cm?

Cesco

Hope this helps.
