Description of document

The Agricultural Metadata Element Set (AgMES), which is an extension to the Dublin Core Metadata Initiative, defines new elements required for describing resources in the domain of agriculture. It was created and is currently maintained by the AGRIS/CARIS Secretariat of the Food and Agriculture Organization of the United Nations.

Introduction

The AgMES (Agricultural Metadata Element set) initiative aims to encompass issues of semantic standards in the domain of agriculture with respect to description, resource discovery, interoperability and data exchange for different types of information resources. AgMES is aimed to act as an umbrella under which namespaces can be defined for newly declared elements that are deemed necessary and are used for different resources (Document like Information Objects or DLIOs, projects, fishing gear presentations, images, technologies, practices, maps etc.) in all areas relevant to food production, nutrition and rural development.

This document refers to metadata elements suitable for describing information objects such as websites, documents, pictures, databases etc. In the description of such resources, the Dublin Core Metadata Initiative (DCMI) [1] is an example of a format that supports a variety of purposes and business models; not surprisingly, it is an increasingly popular candidate for use in resource description and primary resource discovery. However, in the context of agricultural resources, the elements and qualifiers supported by DCMI do not suffice. In light of these additional requirements, new elements, refinements and schemes have been created.

This document is designed to give details of newly defined elements, qualifiers, schemes, and controlled lists required to describe DLIOs in agricultural resources.

There are many more controlled vocabularies or classification schemes in the domain of agriculture that are not yet identified in this document but will be added as they are approved. Here are some standards homepages for easy reference.


The Elements

Element Name: titleSupplement

  Name:

titleSupplement

  Label:

Title Supplement

  Definition:

Secondary information related to the title.

  Comment:

Title Supplement should be used sparingly and only in conjunction with Title element. It should be used to enter:

a) elements on the title page that do not properly belong to the title and subtitle but that are appended to it; and
b) elements taken from elsewhere than the title page that constitute useful additional information to the title.

Supplementary title information includes such phrases as:
    Presented at a meeting of...
    Proceedings of a conference held...
    Based on the work of...

  Element Refined:

DC.Title

  Scheme:

Element Name: creatorCorporate
  Name:

creatorCorporate

  Label:

Corporate Creator

  Definition:

Organization or a group of people identified by a name responsible for creating or making contributions to the intellectual content of the resource.

  Comment:

It is preferred that the value for Corporate Creator is taken from an authority file. If a file is used, in XML one can indicate this by using the attribute “scheme” and in RDF by using “rdf:isdefinedby”.

  Element Refined:

DC.Creator

  Scheme:

free-text or value from an authority file


Element Name: creatorPersonal
  Name:

creatorPersonal

  Label:

Personal Creator

  Definition:

Person responsible for creating or making contributions to the intellectual content of the resource.

  Comment:

It is preferred that the value for Corporate Creator is taken from an authority file. If a file was indeed used, in XML one can indicate this by using the attribute “scheme” and in RDF by using “rdf:isdefinedby”.

  Element Refined:

DC.Creator

  Scheme:

Element Name:creatorConference
  Name:

creatorConference

  Label:

Conference as Creator

  Definition:

Conferences are named meetings of individuals or representatives of various bodies for the purpose of discussing and acting on topics of common interest, or meetings of representatives of a corporate body that constitute its legislative or governing body.

  Comment:

Conferences almost always have a place and date attached to them, and often a number. If a file was indeed used, in XML one can indicate this by using the attribute “scheme” and in RDF by using “rdf:isdefinedby”.

Element Name: publisherPlace
  Name:

publisherPlace

  Label:
  Definition:

The place of publication of an item is the city, town, or other locality associated with the name of the publisher entered in the Publisher Name field.

  Comment:

Normally, the place of publication should be accompanied by the country name. The names may come from a recognized scheme such as AGROVOC ,TGN , or ISO3166 . If a scheme is used, in XML one can indicate this by using the attribute “scheme” and in RDF by using “rdf:isdefinedby”.
