"Solrmarc can index your marc records into apache solr. It also comes with an improved version of marc4j that improves handling of UTF-8 characters, is more forgiving of malformed marc data, and can recover from data errors gracefully. This indexer is used by blacklight (http://blacklight.rubyforge.org) and vufind (http://www.vufind.org/) but it can also be used as a standalone project."

A rant against MARCXML:

"MARCXML isn't as much XML as it is MARC; it's really MARC with a bad hairdo"

Perl extension for handling MARC records.  Version 2 of MARC::Record is now available.

 

Lots of links to metadata webpages

This page includes links to a variety of MARC documents, including formats and code lists.  Also has links to various mappings (crosswalks) to and from MARC.

Crosswalk includes both qualified and unqualified versions of Dublin Core

Karen Coyle's blog posting on MARC and interesting follow-up discussion.   It's also being discussed on the Next Generation Catalog (NCG4LIB) list.  

There are many XML schemas available for modeling MARC data. Most take a literal approach, naming elements and attributes after their corresponding MARC fields, subfields, and indicators. Others represent only a small subset of the data libraries use to describe resources. XOBIS attempts to walk the middle path: describe the full set of library information, but reorganize this information into a structure that empowers the use of library data as just one more information resource available in the digital domain.

The following crosswalk was done by Elizabeth Mangan, Geography and Map Division, Library of Congress.
