YAZ−MARCDUMP

NAME

yaz-marcdump − MARC record dump utility

SYNOPSIS

yaz−marcdump [−i format] [−o format] [−f from] [−t to] [−l spec] [−v] [−c cfile] [−s prefix] [−C size] [−p] [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).

−o format

Specifies output format. Must be one of marcxml, marc (ISO2709), marcxchange (ISO25577), line (line mode MARC).

−f from

Specify the character set from of the input MARC record. Should be used in conjunction with option −t.

−t to

Specify the character set of of the output. Should be used in conjunction with option −f.

−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.

−v

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

−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.

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
