MARC21 (MAchine-Readable Cataloging) standards are a set of digital formats for the description of items such as books developed in the 1960s. The latest MARC standard, MARC 21, was created in 1999 and added formats for authority records, holdings records, classification schedules, and community information, in addition to bibliographic.
EachMARC21 record comprises of 3 aspects:
- the field designations within each record
- the structure of the record
- the actual content of the record itself
Then MARCXML was created as an XML schema based on the common MARC21 standards and is parsable by SnapLogicโs XML parser.
This MARC21 custom snap converts MARC21 to MARCXML using open-source java code available on github using the following URL. GitHub - marc4j/marc4j: Git repository initially imported from the Tigris CVS repo as of 2013.01.25
Once the MARC21 data is converted to MARCXML, SnapLogic can then read in the XML using the XML parser just like any other XML input.
Below is a link to download the MARC21 custom snap as well as a sample MARC21 record to illustrate the complexity of the MARC21 data structure.
