==2.1 General Structure==
UNIMARC is a specific implementation of [[wikipedia:uk:ISO 2709|ISO 2709]], an international standard that specifies the
structure of records containing bibliographic data. It specifies that every bibliographic record prepared
for exchange conforming to the standard must consist of:
:R/T = Record Terminator
[[wikipedia:uk:ISO 2709 |ISO 2709]] further specifies that the data in fields may optionally be preceded by indicators and
subdivided into subfields. UNIMARC, as an implementation, uses the following specific options
allowed under [[wikipedia:uk:ISO 2709|ISO 2709]].
For general information on the format structure see UNIMARC Manual: [[UNIMARC для бібліографічних записів|Bibliographic Format]], [[Структура формату|3Format Structure]].
