This section presents the proposed elements in a hierarchical structure. Preference is given to notation, vocabularies and terms that are currently used in describing agricultural resources. Full description of these elements can be viewed.
Introduction
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 shall be created and linked to the metadata. Element that will have Authority files include: Author, Researcher, Corporate Author, Publisher and Type, qualifiers Event (Conferences, Workshops, Meetings)
The hierarchical notation presents the different levels of description, which is noted by the use of different formats and colours as indicated in the legend in the footnote.
