MARC4J provides an easy to use API for working with MARC (binary), MARCXML, MARC JSON in Java. MARC stands for MAchine Readable Cataloging and is a widely used exchange format for bibliographic data. MARCXML provides a loss-less conversion between MARC (MARC21 but also other formats like UNIMARC) and XML.

Features

The MARC4J library includes:

...

  • Leader leader;
  • List<ControlField> controlFields
  • List<DataField> dataFields
  • List<MarcError> errors

Writers

If you need other xml format output, ou can post-process the result using a Source object pointing to a stylesheet resource and a Result object to hold the transformation result tree.The example below converts MARCJson to MARC XML and transforms the result tree to Dublin Core using the stylesheet provided by The Library of Congress:


Code Block
languagejava
titleFrom Json to Dublin Core data
String stylesheetUrl = "https://www.loc.gov/standards/marcxml/xslt/MARC21slim2OAIDC.xsl";
Source stylesheet = new StreamSource(stylesheetUrl);
Result result = new StreamResult(System.out);
InputStream input = new FileInputStream(INPUT_JSON_FILE);
MarcReader reader = new MarcJsonReader(input);

MarcXmlWriter writer = new MarcXmlWriter(result, stylesheet);
writer.setConverter(new AnselToUnicode());

while (reader.hasNext()) {
    Record record = (Record) reader.next();
    writer.write(record);
}
writer.close();

Testing Marc4j writer

  1. Reading a Marc Json and printing in MARC format. Observation was that if encoding was not used, the MARC generated was invalid
Code Block
import java.io.FileInputStream;
import java.io.InputStream;
import org.marc4j.*;
import org.marc4j.marc.Record;

public class TestMarc4jWriter {

  public static void main(String args[]) throws Exception {
		# The json file used here is referenced above
    InputStream input = new FileInputStream("MarcFileinjsonFormat");
    MarcReader reader = new MarcJsonReader(input);
    MarcWriter writer = new MarcStreamWriter(System.out, "UTF8");


    while (reader.hasNext()) {
        Record record = reader.next();
        writer.write(record);
    }

    writer.close();
}
}

Validating a MARC file locally

An opensource tool MARCEDIT can be used for validating MARC files, and also for conversion
