Where does NS/OS associate file extensions to apps?

Where does one configure which file extensions open which apps?

From reading:
http://docs.sun.com/app/docs/doc/802-2109/6i63jrkbq?a=view

it says:
"The Workspace Manager also uses file name extensions to associate document files with applications. Every application that defines its own data file format appends an identifying extension to the names of its document files. "

but where is this stored?

Thank you.
