Beyond MARC21With thanks to Jean Godby of OCLC Research

The Crosswalk Web Service at OCLCEnables OCLC to translate from one metadata format to another. A “metadata format” is a triple that consists of a metadata schema, a structural encoding, and a character encoding.Supported standards are bibliographic, but the software can handle other types of data.Can be called from any product or service that processes metadata. A version with a slightly different interface resides on the OCLC Enterprise Bus.

Enables OCLC to translate from one metadata format to another.

In sum…The Crosswalk Web service is engineered for reusability.It is abstract enough to handle any kind of metadata markup.It keeps a close connection between human-generated translation logic and executable code. It is flexible enough to handle many use cases.

It is flexible enough to handle many use cases.

AdoptionsThe Crosswalk Web Service has been incorporated into: Connexion Client 2.0 ContentDM Ingest Data Load EnhancementeSerials, eSweepNetLibrary Next Generation CatalogingAdoption is being studied for components of:Digital Collection GatewayWorldCat Cataloging Partners NCIP (NISO Circulation Interchange Protocol)It is being used in research projects:Art and natural history museum metadata (with RLG partners)ISO 8459 bibliographic message exchange (with Janifer Gatenby)

Future prioritiesDevelop a user interface that accepts translation logic and automatically generates Seel scripts.Streamline and enhance some of the Seel language features.Investigate ways to interoperate with the crosswalking software developed at OCLC Leiden.Develop translations for non-bibliographic metadata.

OCLC FRBR Work-set AlgorithmProvides a FRBR-based view of the dataRecords clustered into works using author and title fields from bibliographic and authority records Author names and titles normalized to construct a work key All records with the same key are grouped together in a work set or cluster

4.87 records/work set for multi-record sets

Share data elements across a FRBR Work Set
