NAME

MARC::File::JSON - Convert between MARC::Record objects and JSON formatted data.

SYNOPSIS

use MARC::File::JSON;

my $record = MARC::Record->new_from_json( $json );
$json = $record->as_json;

DESCRIPTION

This module provides routines for converting between MARC::Record objects and serialized JSON data formatted as:

{
  "leader":"01109cam a2200349 a 4500",
  "fields":[
    "001",
    "   89009461 //r92",
    "005",
    "19991006093052.0",
    "010", {
      "subfields":[
        "a",
        "89009461 //r92"
      ],
      "ind1":" ",
      "ind2":" "
    },
    "020",
    ...
  ]
}

INTERFACE

MARC::Record::Generic injects two subroutines into the MARC::Record namespace. Additionally it inherits from MARC::File and includes encode(), decode, and _next() routines, making it compatible with MARC::Batch.

• MARC::Record::new_from_json( $json )

  A package method of MARC::Record which applies the values contained in $json to the object which it returns.

• MARC::Record::as_json( )

  An instance method for a MARC::Record object. Returns the objects values as a string of JSON data.

• encode( MARC::Record $record )

  Returns a JSON string representation of $record.

• decode( $class, $json )

  Converts $json into an instance of MARC::Record, applying the transform in MARC::Record::Generic.
