Using the MarcEdit Terminal

Please see: for the most current information on the command line program options.


MarcEdit includes a separate command-line tool that encapsulates a wide range of functionality.  The tool provides a GUIless interface that can be used within shell scripts or other automation tools. The command-line tool is available in all versions of MarcEdit.  On windows and Linux, the terminal version is run through a separate program: cmarcedit.exe.  On the MacOS version, the terminal is run through the MarcEdit app.  In all examples below, the cmarcedit.exe can be replaced with MarcEdit on MacOS.

The program current provides the following options (these options can be found by entering: >>cmarcedit.exe -help

-s:     Path to file to be processed.
If calling the join utility, source must be files
delimited by the ";" character
-d:     Path to destination file.
If call the split utility, dest should specify a folder
where split files will be saved.
If this folder doesn't exist, one will be created.
-export_delimited:      Export Tab Delimited Records function
-D or -delimiter:       Set the delimiter.
[options:        = tab, [character]

-rules: Rules file for the MARC Validator or Linked Data Tool or export_delimited (depending on context).
-view:  View the specified source file.  Default, 2K will be printed.
-buffer:        Amount of data to be viewed.  This is an optional Parameter.
-pretty:        When paired with the -view command, will always output data in mnemonic format if data is MARC
-mxslt: Path to the MARCXML XSLT file.
-xslt:  Path to the XML XSLT file.

-pd:    [Optional] When a Malformed record is encountered, it will modify the process from a stop process to one where an error is simply noted and a stub note is added to the result file.
-bibframe:      Specifies the current bibframe transformation.  Currently, bibframe2.
Example: >>cmarcedit.exe -s [yourfile] -d [output file] -bibframe -idfield 001 -baseuri

-idfield:       [Optional] Pairs with the bibframe conversion, sets the id field.  Defaults to 001.  Can be a field and subfield combination: i.e.: 035$a
-baseuri:       [Optional] Pairs with the bibframe conversion, sets the base uri.  Defaults to
-output:        [Optional] Pairs with the bibframe conversion, sets schema output. Valid values: rdfxml
-collections:   Print out all Linked Data Collections currently profiled.
-buildlinks:    Specifies the Semantic Linking algorithm
This function needs to be paired with the -options parameter
-options        Specifies linking options to use: example: lcid,viaf:lc,oclcworkid:001,autodetect,3xx
lcid: autodetects main entry
autodetect: autodetects subjects and links to know values
oclcworkid: inserts link to oclc work id if present
3xx: autodetects values in 3xx fields and links to known values
limit: limits values to specific defined collections.  Example: limit:mesh (limits to just mesh headings                rules: path to the linked data rules file.              viaf: linking 1xx/7xx using viaf.  Specify index after colon. If no index is provided, lc is assumed.

Common options:

Translating data from MARC to mnemonic:

>> cmarcedit.exe -s [sourcefile] -d [destfile] -break [-utf8|marc8|raw|pd]

The above command has a number of optional values.  -utf8|marc8|raw set the encoding properties for the MARC file.  If -utf8 is used, the program will assume that the data is in MARC8 or UTF8 and ensure that all data is encoded in UTF8.  The same is true for the marc8 option, though the final output is marc8.  The raw option doesn’t do any encoding.  This is what is used by default.  The pd option tells MarcEdit to stop on error and output the record and error that caused the processing issue.

Translating data from mnemonic to MARC:

>> cmarcedit.exe -s [sourcefile] -d [destfile] -make [-utf8|marc8|raw]

Working with Linked Data:

The linked data option uses the following pattern: cmarcedit.exe –s [sourcefile] –d [destfile] –buildlinks –options [linkoptions]

As noted above in the list, –options is a comma delimited list that includes the values that the linking tool should query.  A user, for example, looking to generate workids and uris on the 1xx and 7xx fields using – the command would look like:

<< cmarcedit.exe –s [sourcefile] –d [destfile] –buildlinks –options oclcworkid,lcid

Users interesting in building all available linkages (using viaf, autodetecting subjects, etc. would use:

<< cmarcedit.exe –s [sourcefile] –d [destfile] –buildlinks –options oclcworkid,lcid,autodetect,viaf:lc

Notice the last option – viaf. This tells the tool to utilize viaf as a linking option in the 1xx and the 7xx – the data after the colon identifies the index to utilize when building links.  The indexes are found in the help (see above).

Translating Data to Bibframe

MarcEdit’s console includes the ability to leverage the U.S. Library of Congress’s bibframe translation profile.  The tool has 3 optional parameters:

  • -idfield: default is 001 but can be a field + subfield (i.e. 035$a)
  • -baseuri
  • -output: Serialization, only rdfxml is currently supported

To use the function — you call the bibframe argument.  The command would look like on windows:

<<cmarcedit.exe -s [sourcefile] -d [destfile] -bibframe

On MacOS, the command would look like:

<< MarcEdit -s [sourcefile] -d [destfile] -bibframe

Additional Examples

Running Tasks via the Terminal.  The -experimental flag is optional, but runs tasks natively and is significantly faster.  This functionality will eventually be standard.

>> cmarcedit.exe -s [sourcefile] -d [destfile] -task [fullpath to task file] -experimental

Validating Records:

>> cmarcedit.exe -s [sourcefile] -validate

Add -clean to remove invalid records:

>> cmarcedit.exe -s [sourcefile] -validate  -clean

Command to tell you if dups exist in a file:

>> cmarcedit.exe -s [sourcefile] -dups?

Command to automate export tab delimited records:

>> cmarcedit.exe -s 100_a_coded_test.mrk -d 001_100.txt -rules UNIMARC_bib_001_100_coded.txt -export_delimited -D \t
