Identifying Libraries with Dictionaries

AppleScript
#1

Is it safe to assume that any library file with a “.sdef” file inside has a dictionary?

#2

You can always test at run-time, but the root element of an sdef is defined as a dictionary here:

#3

Yes. There’s no other reason for adding one.

#4

I have a script that opens a library’s dictionary form a list. Now I test for the .sdef file so only libraries with dictionaries are displayed.
