Access a named range stored in a sheet in a separate sheet?

In my example I have two sheets, Data and Analyze.

If I store a named range in the Data Sheet, lets call it mydata.
Can I access the named range from the second sheet Analyze?

OR
Is the only way possible is the named range must be stored in the documnet to access across sheets?

Yes you can!
eg:

=INDEX('file:///…/…/other_file.ods'#named_range;5)

or place in your example on the Analyze sheet:

=Data.mydata
