NAME

yaz-marcdump - MARC record dump utility

CONTENTS

SYNOPSIS

yaz-marcdump [-i format] [-o format] [-f from] [-t to] [-l spec] [-c cfile] [-s prefix] [-C size] [-n] [-p] [-v] [-V] [file...]

DESCRIPTION

yaz-marcdump reads MARC records from one or more files. It parses each record and supports output in line-format, ISO2709, \m[blue]MARCXML\m[][1], \m[blue]MARC-in-JSON\m[][2], \m[blue]MarcXchange\m[][3] as well as Hex output.

This utility parses records ISO2709(raw MARC), line format, MARC-in-JSON format as well as XML if that is structured as MARCXML/MarcXchange.

MARC-in-JSON encoding/decoding is supported in YAZ 5.0.5 and later.

Note

As of YAZ 2.1.18, OAI-MARC is no longer supported. OAI-MARC is deprecated. Use MARCXML instead.

By default, each record is written to standard output in a line format with newline for each field, $x for each subfield x. The output format may be changed with option -o,

yaz-marcdump can also be requested to perform character set conversion of each record.

OPTIONS

-i format

Specifies input format. Must be one of marcxml, marc (ISO2709), marcxchange (ISO25577), line (line mode MARC), turbomarc (Turbo MARC), or json (MARC-in-JSON).

-o format

Specifies output format. Must be one of marcxml, marc (ISO2709), marcxchange (ISO25577), line (line mode MARC), turbomarc (Turbo MARC), or json (MARC-in-JSON).

-f from

Specify the character set of the input MARC record. Should be used in conjunction with option -t. Refer to the yaz-iconv man page for supported character sets.

-t to

Specify the character set of the output. Should be used in conjunction with option -f. Refer to the yaz-iconv man page for supported character sets.

-l leaderspec

Specify a simple modification string for MARC leader. The leaderspec is a list of pos=value pairs, where pos is an integer offset (0 - 23) for leader. Value is either a quoted string or an integer (character value in decimal). Pairs are comma separated. For example, to set leader at offset 9 to a, use 9=a.

-s prefix

Writes a chunk of records to a separate file with prefix given, i.e. splits a record batch into files with only at most "chunk" ISO2709 records per file. By default chunk is 1 (one record per file). See option -C.

-C chunksize

Specifies chunk size; to be used conjunction with option -s.

-p

Makes yaz-marcdump print record number and input file offset of each record read.

-n

MARC output is omitted so that MARC input is only checked.

-v

Writes more information about the parsing process. Useful if you have ill-formatted ISO2709 records as input.

-V

Prints YAZ version.

EXAMPLES

The following command converts MARC21/USMARC in MARC-8 encoding to MARC21/USMARC in UTF-8 encoding. Leader offset 9 is set to a. Both input and output records are ISO2709 encoded.

    yaz-marcdump -f MARC-8 -t UTF-8 -o marc -l 9=97 marc21.raw >marc21.utf8.raw
  

The same records may be converted to MARCXML instead in UTF-8:

    yaz-marcdump -f MARC-8 -t UTF-8 -o marcxml marc21.raw >marcxml.xml
  

Turbo MARC is a compact XML notation with same semantics as MARCXML, but which allows for faster processing via XSLT. In order to generate Turbo MARC records encoded in UTF-8 from MARC21 (ISO), one could use:

    yaz-marcdump -f MARC8 -t UTF8 -o turbomarc -i marc marc21.raw >out.xml
