Concise UNIMARC Classification Format (20001031)

Introduction

Notation Conventions

The following notation conventions are adopted in the listing of fields, indicators and subfields and in the description and examples relating to them.

  • subfield identifier. The dollar sign '$' has been used to represent ISl of ISO 646 as the first character of the subfield identifier.

  • blank. The hash sign '#' has been used in the examples to represent 2/0 in ISO 646, the space character. It thus indicates a blank or space where the presence of or necessity for a space in the text of the Manual is not obvious from the context.

  • field separator. The commercial at sign '@' has been used to represent IS2 of ISO 646 as the field separator in the complete examples [none available yet]. However this is not included in the examples of the use of individual fields although in fact IS2 terminates each field in the UNIMARC record.

  • end of record mark. The per cent sign '%' has been used to represent IS3 of ISO 646 as the end of record mark in the complete examples [none available yet].

  • 'not defined'. The phrase 'not defined' associated with an indicator position means that no values have been given to that position and the indicator position is filled with a blank.

  • non-sorting characters. The characters ¹NSB¹ and ¹NSE¹ have been used in some examples as symbols for ISO 6630 Bibliographic Control set positions 08/08 and 08/09 respectively. They enclose characters which are to be ignored for sorting purposes.

Control Subfields

$2 The source of the recorded change, expansion, authorised non schedule development (e.g UDC *...), and index terms. To be used within the 2-- Heading block, 3-- History notes and 7-- Index term fields.

$3 Classification record number. To be used whenever there is a relationship with another classification authority record.

      n Not Applicable

      'n' is required only if there are following specific values, e.g. $5k is used instead of $5knnn; in $5knna 'n' must be used to indicate that the 'a' means 'History reference'. It follows that $5/3 value 'n' will never be used.

$7 Script. Identifies the data in the field where an index term or note is carried in multiple scripts. To be used within the 2-- Heading block, 3-- History notes and 7-- Index term fields.

$8 Language. Identifies the language when the field uses terms in a language other than that of cataloguing. To be used within the 2-- Heading block, 3-- History notes and 7-- Index term fields.

$8 Link and sequence number. Because the note fields and number-building fields may rely on correct order for interpretation of the data, this subfield is provided for linking and sequencing fields. Using this subfield when necessary, one can indicate the order in which fields must remain to provide comprehensible instructions. This ability is particularly important for the DDC because of the editorial style rules that specify the order in which notes should appear in the printed schedules and tables. To be used [to be completed].

Record Label

Definition

This area of the record contains general information which may be needed in processing the record, constituted according to the provisions of ISO 2709.

Occurrence

The record label occurs at the beginning of every record. It is mandatory and not repeatable.

Tag, Indicators, and Subfields

The record label has no tag, indicators, or subfield identifiers.

Fixed Length Data Elements

These data elements are identified by character position within the label. The label as a whole is always 24 characters in length. Conventionally the character positions are numbered 0 to 23.

Notes on Field Contents

The Record Label (also known as leader) is found at the beginning of each UNIMARC record and contains data for processing the record. Character positions 10, 11, 20-23 contain specific fixed values which may be generated programmatically by the computer. Character positions 0-4 and 12-16 contain numerical data indicating the number of characters in certain areas of the record; these can be calculated by the computer when the record is formatted. Values for the character positions 5, 6, 17 may be translated from data in the source record by conversion program or, where UNIMARC is being used as the source format, assigned manually.

0-4 Record length Five decimal digits, right justified, with zero fill where necessary, representing the number of characters in the entire record, including the label itself, the directory, and the variable fields. This data element is normally calculated automatically when the total record is assembled for exchange.

5 Record Status
A single digit, denoting the processing status of the record.

    a = record with an increase in encoding level
    c = corrected or revised record
    d = deleted record
    n = new record

001 Record Identifier

Field Definition This field contains characters uniquely associated with the record, i.e. the control number for the record of the agency preparing the record. Occurrence Mandatory. Not repeatable.

Indicators In conformance with ISO 2709 this field does not have indicators.

Subfields In conformance with ISO 2709 this field does not contain subfields.

Notes on Field Contents There are no restrictions on the form of the record identifier.

When the record identifier consists of or incorporates any form of an International Standard Number, other identifiable number such as a national number, or other data such as country of publication, this information is nevertheless to be entered in the field specified for that data in addition to recording it as the record identifier in this field.

Related Fields An agency may be using other separately identified numbers such as ISBN or National Bibliography Number as a Record Identifier. See Notes on Field Contents above for treatment in these cases.

003 INSTITUTION OF RECORD IDENTIFIER
This field contains a code identifying the source of the record identifier.

035 SYSTEM CONTROL NUMBER

$a General Processing Data

$a/00-07 Date Entered on File

    Eight numeric characters in ISO standard form (ISO 8601:1988) for dates: YYYYMMDD where YYYY represents the year, MM the month with leading 0 if necessary and DD the day of the month with leading 0 if necessary.

    The date will usually be the date when the record was originally created and entered into machine-readable form, to give some idea of the age of the record. A record corrected because of errors in keying or editing will not have a change of date. On exchange, the record should also retain its original date.

    EX1
    Character positions 0-7: 19990516
    The record was originally entered into a machine-readable data file on 16th May 1999.

$a/14 Synthesised Number Indication

    (indicates whether the number has been derived/calculated, etc.)

$a/15 Display Controller

    a Displayed in Standard Schedules or Tables
    b Extended Display

$a/16-18 Language of Cataloguing (Mandatory)

    A three-character code indicating the language used in cataloguing. For the list of codes see Appendix A. If a source record is completely multi-lingual, i.e. all information not from the title page is repeated in more than one language, it is recommended that a separate UNIMARC record should be produced, as required, for each language.

    UNIMARC has no mechanism to denote the language of individual fields throughout the format.

$a/19 Transliteration Code

    UNIMARC assumes the utilisation of international standards. However, in the area of conversion of scripts, international standards are not yet completely adequate, and other schemes may be used. This code indicates whether or not an ISO transliteration scheme is used in the record.

    a = ISO transliteration scheme
    b = other
    c = multiple transliterations: ISO or other schemes
    y = no transliteration scheme used

$a/20-23 Character Sets (Mandatory)

    Two two-character codes designating the principal graphic character sets used in communication of the record. Positions 20-21 designate the G0 set and positions 22-23 designate the Gl set. If a Gl set is not needed, positions 22-23 contain blanks. For further explanation of character coding see Appendix J. The following two-character codes are to be used. They will be augmented as required.

    01 = ISO 646, IRV version (basic Latin set)
    02 = ISO Registration # 37 (basic Cyrillic set)
    03 = ISO 5426 (extended Latin set)
    04 = ISO 5427 (extended Cyrillic set)
    05 = ISO 5428 (Greek set)
    06 = ISO 6438 (African coded character set)
    07 = ISO 10586 (Georgian set)
    08 = ISO 8957 (Hebrew set) Table 1
    09 = ISO 8957 (Hebrew set) Table 2
    10 = [Reserved]
    11 = ISO 5426-2 (Latin characters used in minor European languages and obsolete typography)
    50 = ISO 10646 Level 3 (Unicode)

    Note that ISO 10646, being a 16-bit character set, contains all necessary characters. When positions 26-27 contain '50' this will be used for the C0, C1 and G0 sets. Positions 28-29 will contain blanks.

$a/24-27 Additional Character Sets

    Two two-character codes indicate up to two additional graphic character sets used in communication of the record. The two-character codes specified for character positions 20-23 are used. Positions 24-25 designate the G2 set and positions 26-27 designate the G3 set. If no additional character sets are needed the bytes contain blanks.

$a/28-29 Script of Cataloguing

    A two-character code indicating the alphabet of the title used as the title proper or, in the case of serials, the keytitle. This refers to the alphabet in the source item, not the character set of the record.

    The following codes are recommended in the absence of any international standard set of codes. (Please note that ISO/CD 15924 "Information and documentation - Code for the representation of names of scripts" is under development by ISO/TC 46/SC 2.)

      ba = Latin
      ca = Cyrillic
      da = Japanese - script unspecified
      db = Japanese - kanji
      dc = Japanese - kana
      ea = Chinese
      fa = Arabic
      ga = Greek
      ha = Hebrew
      ia = Thai
      ja = Devanagari
      ka = Korean
      la = Tamil
      ma = Georgian
      zz = Other

    The script code is optional if the script is the usual one relating to the language found in field 101 $g or in the absence of subfield $g, $a.

254 General Explanatory Index Term

Field Definition
This field contains a general explanatory term from the index to the classification scheme that is identified in field 184 (Classification Scheme and Edition). Field 254 is appropriate only in an index term only record (100$a/06, Kind of record, code c) that is created because the index term cannot be accommodated in a 70X-75X Index Term field in a schedule or table record (100$a/06, code a or b) that contains a class number in field 250 (Class Number). This occurs when the index term is not associated with one class number or span. Field 753 (Index Term--Uncontrolled) is always used in a record containing field 254 to direct the user to different locations within the classification scheme for classifying the topic.

856 Electronic Location and Access

Field Definition
This field contains the information required to locate an electronic item. The information identifies the electronic location containing the item or from which it is available. It also contains information to retrieve the item by the access method identified in the first indicator position. The information contained in this field is sufficient to allow for the electronic transfer of a file, subscription to an electronic journal, or logon to an electronic resource. In some cases, only unique data elements are recorded which allow the user to access a locator table on a remote host containing the remaining information needed to access the item. It may be used to link to an electronic resource intended to supplement the classification scheme, e.g. an image of a map.

Occurrence
Optional. Repeatable when the location data elements vary (subfields $a, $b, $d) and when more than one access method may be used. It is also repeatable whenever the electronic filename varies (subfield $f), except when a single intellectual item is divided into different parts for online storage or retrieval.

Indicators
Indicator 1: Access Method

    # No information provided
    0 Email
    1 FTP
    2 Remote login (Telnet)
    3 Dial-up
    4 HTTP
    7 Method specified in subfield $y

Indicator 2: blank (not defined)

Subfields
$a Host Name (Repeatable)
$b Access Number

    The access number associated with a host. It can contain the Internet Protocol (IP) numeric address if the item is an Internet resource, or a telephone number if dial-up access is provided through a telephone line. This data may change frequently and may be generated by the system, rather than statically stored. Subfield $b may be repeated if all the other information in the field applies. A telephone number is recorded as follows: [country code]-[area code]-[telephone number]. Examples: 49-69-15251140 (a number in Frankfurt, Germany); 1-202-7076237 (a number in Washington, D.C., U.S.A). If an extension is applicable, include it after the telephone number preceded by 'x'. Example: 1-703-3589800x515 (telephone number with extension). Repeatable.
$c Compression Information (Repeatable)
$d Path (Repeatable)
$e Date and Hour of Consultation and Access
    The time, in the form YYYYMMDDHHMM, at which the electronic item was last accessed. Not repeatable.
$f Electronic Name
    The electronic name of a file as it exists in the directory/subdirectory indicated in subfield $d on the host identified in subfield $a. Subfield $f may be repeated if a single logical file has been divided into parts and stored under different names. In this case, the separate parts should constitute a single bibliographic item. In all other cases, a file that may be retrieved under different filenames contains multiple occurrences of field 856, each with it corresponding electronic name in subfield $f. A filename may include wildcard characters (e.g., '*' or '?') if applicable, with a note in subfield $z explaining how files are named. NOTE: Filenames may be case sensitive for some systems. This subfield may also contain the name of the electronic publication or conference. Repeatable.
$g Uniform Resource Name
    The URN, which provides a globally unique location independent identifier. Repeatable.
$h Processor of Request
    The username, or processor of the request; generally the data which precedes the at sign ('@') in the host address. Not repeatable.
$i Instruction
    An instruction or command needed for the remote host to process a request. Repeatable.
$j Bits Per Second
    The lowest and highest number of bits (binary units) of data that can be transmitted per second when connected to a host. The syntax for recording the number of bits per second (BPS) should be: [Lowest BPS]-[Highest BPS]. If only lowest given: [Lowest BPS]-. If only highest given: -[Highest BPS]. Not repeatable.
$k Password
    Used to record general-use passwords, and should not contain passwords requiring security. Not repeatable.
$l Logon/Login
    General-use logon/login strings which do not require special security. Not repeatable.
$m Contact for Access Assistance Repeatable.
$n Name of Location of Host in Subfield $a. Not repeatable.
$o Operating System
    For information, the operating system used by the host specified in subfield $a is indicated in this subfield. Not repeatable.
$p Port
    The portion of the address that identifies a process or service in the host. Not repeatable.
$q Electronic Format Type
    Contains an identification of the electronic format type, which determines how data are transferred through a network. Usually, a text file can be transferred as character data which generally restricts the text to characters in the ASCII (American National Standard Code for Information Interchange) character set (i.e., the basic Latin alphabet, digits 0-9, a few special characters, and most punctuation marks). Text files with characters outside of the ASCII set, or non-textual data (e.g., computer programs, image data) must be transferred using another file transfer mode, usually binary mode. Electronic format type may be taken from lists such as registered Internet Media types (MIME types). Not repeatable.
$r Settings
    The settings used for transferring data. Included in settings are: 1) Number Data Bits (the number of bits per character); 2) Number Stop Bits (the number of bits to signal the end of a byte); and 3) Parity (the parity checking technique used). The syntax of these elements is:
    [Parity]-[Number of Data Bits]-[Number of Stop Bits]. If only the parity is given, the other elements of settings and their related hyphens are omitted (i.e., [Parity]). If one of the other two elements is given, the hyphen for the missing element is recorded in its proper position (i.e., [Parity]--[Number of Stop Bits] or [Parity]-[Number of Data Bits]-). The values for parity are: O (Odd), E (Even), N (None), S (Space), and M (Mark). Not repeatable.
$s File Size
    The size of the file as stored under the filename indicated in subfield $f. It is generally expressed in terms of 8-bit bytes (octets). It may be repeated in cases where the filename is repeated and directly follows the subfield $f to which it applies. This information is not given for journals, since field 856 relates to the entire title, not to particular issues. Repeatable.
$t Terminal Emulation (Repeatable)
$u Uniform Resource Locator
    The Uniform Resource Locator (URL), which provides electronic access data in a standard syntax. This data can be used for automated access to an electronic item using one of the Internet protocols. Field 856 is structured to allow the creation of a URL by combining data from other 856 subfields. Subfield $u may be used instead of those separate subfields or in addition to them. Not repeatable.
$v Hours Access Method Available
    The hours that access to an electronic resource is available at the location indicated in this field. Repeatable
$w Record Control Number (Repeatable)
$x Nonpublic Note (Repeatable)
$y Access Method
    The access method when the first indicator position contains value 7 (Method specified in subfield $y). This subfield may include access methods other than the main TCP/IP protocols specified in the first indicator. The data in this subfield corresponds with the access schemes specified in Uniform Resource Locators (URL) (RFC 1738), a product of the Uniform Resource Identifiers Working Group of the IETF. The Internet Assigned Numbers Authority (IANA) maintains a registry of URL schemes and defines the syntax and use of new schemes. Not repeatable.
$z Public Note (Repeatable)

9-- National Use Block

Definition and Scope of Fields
This block is reserved for national use by agencies where UNIMARC is the basis of the domestic format. It is recommended that fields in this block be excluded from international exchange media. In cases of difficulty, it would be a matter for international agreement as to whether particular types of data should be held in a local field. Agencies using this block may, if they wish, come to an agreement over common use of fields; but this is optional.

Notes on Field Contents
These fields may contain any information which is of local, as opposed to international, importance.

Related Fields, Indicators, and Subfields
All -9- and --9 fields throughout the format are reserved for national and local use; their definitions and indicator and subfield values remain undefined by the Permanent UNIMARC Committee. This is also true of indicator value 9 and subfield $9.
