The paper presents qualifiers of the proposed Dublin Core elements for documents and document-like information resources. Preference is given to notation, vocabularies and terms that are currently used in describing agricultural resources.
As indicated below, agricultural information resource can be described from broad to very specific levels. The top level in the hierarchy defines the Dublin Core elements and additional proposed elements while the qualifiers suitable for agricultural resource description are shown down the hierarchy. A more detailed description of all the elements and qualifiers, including information on definitions, rules, and data typing has been done and is available.
Important notice:
1. The element Creator has been revised to represent all the agent elements namely, Creator, Contributor and Publisher.
2. Some attributes of elements that have been in the past considered necessary in resource description are not included in this description of a specific resource because this information is currently not considered as primary information that is important for discovery of a particular resource. However to include this information which is also important for resource discovery at a secondary level, Authority files will be created and linked to the metadata. Element that will have Authority files include: Author, Corporate Author, Publisher and Type, qualifier Event (Conferences, Workshops, Meetings)
The hierarchical notation presents the different levels of description that is noted by the use of different formats and colours as indicated in the legend below
