Interoperability between metadata formats Mapping ROADS/IAFA templates to Dublin Core Michael Day UKOLN: The UK Office for Library and Information Networking, University of Bath, Bath, BA2 7AY, United Kingdom http://www.ukoln.ac.uk/ m.day@ukoln.ac.uk November 1997

The most widely used ROADS/IAFA templates are the DOCUMENT and SERVICE templates. The mappings in this document will therefore concentrate on these template types:

• 1. ROADS DOCUMENT template to Dublin Core
• 2. ROADS SERVICE template to Dublin Core
• 3. ROADS IMAGE template to Dublin Core

1. Summary mapping from ROADS/IAFA DOCUMENT template to Dublin Core.

NOTES

Qualifiers: Dublin Core has in the past supported the idea of defining qualifiers. This is currently under discussion, so reference has only been made here to those qualifiers referred to in the Dublin Core/USMARC crosswalk: http://lcweb.loc.gov/marc/dccross.html.

Title: ROADS templates permit the inclusion of alternative and short titles. Dublin Core does allow for the inclusion of more than one title but a scheme for abbreviated or other titles is not currently defined.

Admin-name: The name of a administrator could be included under Dublin Core "Contributors", but the term might have to be used as a "role" qualifier, e.g.

Contributors (type=admin): Oxford
University Computing Service

Format and Character-set: The ROADS Format element is designed to describe the formats in which a resource is available, while the Character-Set attribute would include well-known information about the character-set used, e.g. ASCII. This information might be usefully added to the Dublin Core "Format" attribute, so the information in both fields could be mapped there.

Subject-Descriptor-Scheme and Subject-Descriptor: The Dublin Core "Subject" element can be qualified with a scheme. When mapping from ROADS templates the Subject-Descriptor-Scheme attribute should become the "scheme", while the Subject-Descriptor would become the attribute, e.g.:

Subject-Descriptor-Scheme-v1: DDC
Subject-Descriptor-v1: 027.00254

to:

Subject (scheme=DDC): 027.00254

Variants: ROADS templates are designed to cope with variants, e.g. a document in more than one language can be described. Variants are identified in ROADS templates in the following way:

Language-v1: English
Language-v2: German
URL-v1:http://www.ub2.lu.se/tk/demos/DO9603-meng.html
URL-v2:http://www.ub2.lu.se/tk/demos/DO9603-manus.html

Dealing with these variants, where present, could be problematic, although it is possible that each variant could form a separate Dublin Core record

Administrative metadata: The ROADS template contains a lot of administrative metadata which is not relevant to the Dublin Core context

2. Summary mapping from ROADS/IAFA SERVICE template to Dublin Core.

NOTES

Comments are much the same as for the DOCUMENT template above. There is possibly a need for Contributor-Name and Sponsor-Name to map to the Dublin Core "Contributors" element, but "roles" would have to be defined for this

3. Summary mapping from ROADS/IAFA IMAGE template to Dublin Core.

NOTES

See comments on DESCRIPTION template.
