UNIMARC is designed according to an agreed set of principles. These have been adopted for
''UNIMARC Holdings Format''.
==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:
:- a '''RECORD LABELRecord label''' consisting of 24 characters;:- a '''DIRECTORYDirectory''' consisting of a 3-digit tag of each data field, along with its length and its starting character position relative to the first data field;:- '''DATA FIELDSData fields''' of variable length, each separated by a field separator, with the following layout:
{| class="wikitable"
|-
| RECORD LABEL Record label || DIRECTORY Directory || DATA FIELDS Data fields|| R/T
|}
: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]].
