yaz-marcdump - MARC record dump utility

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, MARCXML, MarcXchange as well as Hex output.

This utility parses records ISO2709(raw MARC) as well as XML if that is structured as
MARCXML/MarcXchange.

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), or turbomarc (Turbo MARC).

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

-f from
Specify the character set from 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 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 record 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 prints record number and input file offset of each record read.

-n
MARC output is omitted so that MARC input is only checkecd.

-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
