[Koha] On a format of 'Framework code'

[zolot]

Hi Koha-community,

I have the following questions to "Koha 3.14 Manual (en)".

1) Does a Koha-term 'framework' denote  the same object as a 'Field Definition Table' in CDS/ISIS ? 

2) What format has a 'Framework code' in the window 'Add framework' ?    Example ?
(A path to this window: 
Home > Administration > MARC frameworks > Add framework).

Wishes,

Gennady
