The Z39.50 Cross-Domain Attribute Set

Version 1.4

1999/08/04

Scope

The Z39.50 Cross Domain (XD) Attribute Set allows a client to perform simple non-domain-specific searches of a database. It is not intended for sophisticated domain-specific searches or for searches where semantic precision is required. Such searches should use domain-specific attribute sets. Cross Domain searches are semantically fuzzy.

The XD Attribute Set

Access Point Attribute Type

The values and semantics of the Access Point attributes are taken from the definitions of the Dublin Core elements, with the exception of Name which the Z39.50 Implementors Group has chosen to create from an aggregation of the DC Creator, Editor and Publisher elements.

Further Reading

Z39.50 Attribute Architecture -- Version 1.1 explains the attribute architecture underlying the Cross Domain Attribute Set. It explains how attributes interact including attributes from other attribute sets.

A document has been produced explaining the rationale behind the Cross Domain Attribute Set. It can be found at http://www.oclc.org/~levan/docs/crossdomainattributesetcommentary.html.

The Dublin Core Metadata Initiative has definitions of the DC elements as well as other information.

 

Appendix 1: XD/tagSet-G Crosswalk

The following table shows how the Cross Domain attribute set Access Points relate to the tagSet-G elements available for metadata retrieval in Z39.50. The purpose is not to declare the two columns to be semantically identical. The purpose is to show how the semantically precise elements in the right column would map to the intentionally semantically fuzzy Access Points in the left column. The elements in the right column often have an is-a-kind-of relationship with the attributes in the left column.

Appendix 2: XD/Bib-1 Crosswalk

The following table shows how the Cross Domain attribute set Access Points relate to the Bib-1 Use attributes. The purpose of this appendix is not to declare the two columns to be semantically identical. The purpose is to show how the semantically precise Use attributes in the right column would map to the intentionally semantically fuzzy Access Points in the left column. The attributes in the right column often have an is-a-kind-of relationship with the attributes in the left column.

Appendix 3: XD/GILS Crosswalk

The following table shows how the Cross Domain Attribute Set Access Points relate to the GILS Use attributes. Since the GILS Attribute Set inherits the Bib-1 Attribute Set Use attributes, Appendix 2 also applies here. The purpose of this appendix is not to declare the two columns to be semantically identical. The purpose is to show how the semantically precise Use attributes in the right column would map to the intentionally semantically fuzzy Access Points in the left column. The attributes in the right column often have an is-a-kind-of relationship with the attributes in the left column.
