A python library for creating MARC21 records with an extendible and mutable dictionary of allowed MARC21 tags and subfields.

Project description

marc21 module

marc21 is a Python library for writing marc21 bibliographic records.

marc is an acronym for MAchine Readable Catalogue.

Installation

Use the Python package manager pip to install marc21.

pip install marc21

Usage

import marc21

# view recognized marc21 fields and subfields in json format
# the information is taken from the website of the Library of Congress
# the option True denotes to include the description of the field/subfield
print(get_dictionary(True))

# create marc21 data transfer object
dto = MarcDto()

# add the control fields  (please note when outputting the record the fields gets sorted)
# control fields in marc21 have a data field and no subfields
fld = dto.create_field(tag='001', data='3303902')
dto.insert_field(fld)

# this can also be done in one line
dto.insert_field(dto.create_field(tag='003', data='LoC'))

# add fields with subfields
# with default indicators as double space '  '
fld = dto.create_field(tag='010')
fld.addSubField(tag='a', value='83165326')
dto.insert_field(fld)

# or with specific indicators
fld = dto.create_field(tag='100', indicators='1 ')
fld.addSubField(tag='a', value='Orwell, George')
fld.addSubField(tag='d', value='1903-1950')
dto.insert_field(fld)

# subfields can also be chained
fld = dto.create_field(tag='245', indicators='10')
fld.addSubField(tag='a', value='1984').addSubField(tag='b', value='a novel').addSubField(tag='c',
                                                                                         value='by George Orwell')
dto.insert_field(fld)

# fields do not need to be added in order
# indicators can also be set after creating the field
fld = dto.create_field(tag='240', indicators='10')
fld.addSubField(tag='a', value='Nineteen eighty-four')
dto.insert_field(fld)

# and this can also be done on one line
dto.insert_field(dto.create_field(tag='300').addSubField(tag='a', value='267 p. ;').addSubField(tag='c', value='21 cm'))

# when the record is finished, it can be printed

print(dto)

Which results in:

^^001^_3303902
^^003^_LoC
^^010  ^_a83165326
^^1001 ^_aOrwell, George^_d1903-1950
^^24010^_aNineteen eighty-four
^^24510^_a1984^_ba novel^_cby George Orwell
^^300  ^_a267 p. ;^_c21 cm

In order to change the default record-separator (^^) and field-seperator (^_), one can call set_separators before printing the MarcDto instance

dto.set_separators(field_separator='  ', subfield_separator=' $')

print(dto)

extending the dictionary

The marc21 standard reserved the 9xx range of fields for custom-fields.

This library supports the addition of new fields and the alteration of existing fields.

    # create a MarcField, separate SubFields, link them together adn add them to the dictionary

    mf = MarcField(tag='905', type='d', repeatable=False, description='Address')
    sf = SubField(tag='a', repeatable=False, description='country')
    mf.add_SubField(new_sf=sf)
    sf = SubField(tag='b', repeatable=False, description='city')
    mf.add_SubField(new_sf=sf)

    add_field_to_list(mf)

    # Or do it in one go, adding the subfields as a list 
    add_field_to_list(MarcField(tag='908', type='d', repeatable=True, description='Fictional Character', subfields=[
        SubField(tag='a', repeatable=False, description='Name'),
        SubField(tag='b', repeatable=True, description='Characterization')
    ]))

    # Or in bulk, add a list of MarcFields to the dictionary
    add_additional_fields_to_list( [
        MarcField('400', 'd', True, 'alternative name', True, '  ', '', [
            SubField('a', False, 'full name'),
            SubField('3', False, 'name use'),
            SubField('2', False, 'source')
        ]),
        MarcField('671', 'd', True, 'title URLs', True, '  ', '', [
            SubField('g', False, 'type'),
            SubField('u', False, 'url'),
            SubField('2', False, 'source')
        ]),
        MarcField('902', 'd', True, 'ISSN', True, '  ', '', [
            SubField('a', False, 'ISSN'),
            SubField('2', False, 'source')
        ])
    ])

Exceptions

A MarcException is raised when:

  • You try to add a subfield without a tag
  • You try to add a subfield without a value
  • You try to add a field with a unknown type (other c-ontrol or d-ata)
  • You supplied to few information to add a subfield to a field
  • You try to add a non-repeatable subfield more than once
  • You try to add a non-defined subfield to a field (not in dictionary)
  • You try to add a non-repeatable field more than once
  • You try to add a non-defined field (not in dictionary)

API

Overview classes

  • MarcDto : marc data transfer object, holds up to 1 record at a time
  • CField : internal definition of a control field
  • DField : internal definition of a data field
  • BaseField : internal base class for CField and DField
  • MarcField : external definition of a field in a marc record (can be a CField or DField)
  • SubField : external definition of a subfield for MarcField of type 'd' (DField)
  • MarcDictionary : internal dictionary containing the definition of the marc fields
  • MarcException : custom exception (see section Exceptions above)

MarcDto

  • MarcDto()

    initializes a new record

  • repr([show_description:bool = False])

    When show_description is supplied as True, the fields and subfields will contain the description of these fields

  • len([count_characters:bool = False])

    if count_characters is omitted or supplied as False this method returns the number of fields in the record otherwise is returns the total number of characters in the fields

  • json()

    returns json representation of the record

    [
      {
      	'tag': <tag>,
      	'...': ''
      },
      {
      	'tag': <tag>,
      	'...': ''
      },
      ...
    ]
    
  • set_separators(field_separator: str, subfield_separator:str)

    if both the field_separator and subfield_separator are non-empty strings the supplied separators will be used within the representation of the record

    <field_separator> for control fields <field_separator>[<subfield_separator>]+

  • create_field(tag: str, [indicators: str = ''], [data: str = ''], [subfields = None]) -> CField | DField

    prepares a new field for the current record (but does not insert it yet) if tag does not point to an existing field definition in the MarcDictionary, a MarcException is raised. depending on the field definition:

    • the field created is a control field (CField) or data field (DField).
    • if is checked whether a field if repeatable or not (and whether it is already present in the current record)

    Depending on the type of the created field:

    • control field (CField): the data argument is used
    • data field (DField): the indicators and subfields are used

    returns the prepared field

  • insert_field(marc_field: CField | DField)

    inserts the field to the current record if the field is not an exact duplicate of a field already present in the record

  • is_tag_present(tag:str)

    returns true if at least one field with the supplied tag is present in the current record

  • perform_filter(tag_present: str, tag_remove: str)

    if at least one field with the supplied tag_present is present in the current record, fields with the supplied tag_remove will be removed from the current record

CField (subclass of BaseField)

  • CField(tag: str, description: str, data: str)

    Initializes a new control field (CField)

  • repr([show_description: bool = False])

    returns the contents of the field. The format depends on the value of show_description: if show_description is False: <field_separator> if show_description is True : <field_separator> []

  • json()

    returns the json representation of the field as:

    {
       'tag': <tag>,
       'data': <data>
    }
    

DField (subclass of BaseField)

  • DField(tag:str, description: str, inidicators: str, subfields: list[SubField])

    Initializes a new data field (DField)

  • repr([show_description: bool = False])

    returns the contents of the field. The format depends on the value of show_description: if show_description is False: <field_separator>[<subfield_separator>]+ if show_description is True : <field_separator> [] [<subfield_separator>]+

  • json()

    returns the json representation of the field as:

    {
        'tag': <tag>,
        'indicators': <indicators>
        'subfields': [
           {
      	    'tag': <tag>
      		'value': <value>
      	 },
           {
      	    'tag': <tag>
      		'value': <value>
      	 },
           ...
        ]
    }
    
  • addSubField(tag: str, value: str)

    if tag does not refer to a subfield defined for current DField tag a MarcException is raised if defined subfield is not repeatable and it is already in the subfield list for the DField a MarcException is raised

    a new SubField object is created and added to the list of subfields for the DField

MarcField

This class is primarily used in the MarcDictionary and used to instantiate CField and DField objects

  • MarcField(tag: str, fieldtype: str, repeatable: bool = False, description: str = 'not supplied', has_indicators: bool = True, indicators: str = ' ', data: str = ' ', subfields: Optional[list[SubField]] = None)

    initializes a new MarcField object

    • fieldtype is 'c' for control field or 'd' for data field
    • repeatable denotes whether more than 1 instance of this field can exist in a record
    • has_indicators denotes whether the field uses indicators

    if fieldtype is not 'c' or 'd' a MarcException is raised if fieldtype is 'c' has_indicators is set to False

  • json()

    returns a json representation of the MarcField

    depending on the fieldtype as

    • 'c':
    {
      'tag': <tag>,
      'fieldtype': <fieldtype>,
      'description': <description>
    }
    
    • 'd':
    {
      'tag': <tag>,
      'fieldtype': <fieldtype>,
      'description': <description>,
      'has_indicators': <has_indicators>,
      'indicators': <indicators>,
      'subfields': [
         [ { <subfield> } ]+
      ]
    
  • add_SubField([new_sf: SubField = None], [tag: str = ''], [repeatable: bool = False], [description: str = ''])

    if both new_sf is None and tag is empty a MarcException is raised

    if new_sf is None, but tag is supplied a new SubField instance is created with the tag, repeatable and description

    if new_sf.repeatable is False, it is checked if no other instance of the subfield is already present in the list of subfields, otherwise a MarcException is raised.

    the new subfield is added to the list of subfields of the current MarcField.

  • is_subfield_present(tag: str)

    returns True if a subfield with the given tag is present in the list of subfields of the current MarcField

  • get_subfields()

    returns the list of subfields for t he current MarcField, if the fieldtype is 'd', otherwise an empty list.

SubField

  • SubField([tag: str = ''], [repeatable: bool = True], [description: str = ''], [value: str = 'dummy'])

    initializes a new SubField

    if either tag or value is an empty string a MarcException is raised

  • repr([show_description: bool = False])

    if show_description is False returns otherwise returns []

  • json()

    returns the json representation of the current subfield

    {
      'tag': <tag>,
      'description': <description>,
      'value': <value>
    }
    

ISO 2709 Support

You can serialize a MarcDto to ISO 2709 (binary MARC21 format) and back using the provided functions:

🔄 Convert to ISO 2709

from marc21 import MarcDto, to_iso2709

record = MarcDto()
record.insert_field(record.create_field(tag="001", data="123456"))
...
binary = to_iso2709(record)
with open("record.iso2709", "wb") as f:
    f.write(binary)

🔁 Load from ISO 2709

from marc21 import from_iso2709

with open("record.iso2709", "rb") as f:
    binary = f.read()
record = from_iso2709(binary)
print(record.to_string())

MARCXML Support

The library can also generate and read MARCXML format.

🔄 Convert to MARCXML

from marc21 import to_marcxml

xml_string = to_marcxml(record)
print(xml_string)

🔁 Load from MARCXML

from marc21 import from_xml

record = from_xml(xml_string)
print(record.to_string())

Both formats support full round-trip conversion, and are verified via unit tests for integrity. These functions are especially useful for interoperability with systems like library catalogs, OAI-PMH services, and archival platforms.
