Date Issued 2010-11-11

Description This document defines the metadata terms of the AgMES Namespace, and includes properties and encoding schemes required for describing resources in the domain of agriculture. It was created and is currently maintained by the Food and Agriculture Organization of the United Nations.

1. 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. The AgMES metadata terms can be defined for newly declared elements that are deemed necessary and are used for different resources (bibliographic references or DLIOs, projects, 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) is widely re-used and as an example of a format that supports a variety of purposes and business models. Essentially in the context of agricultural resources, it was discovered that the properties and sub-properties proposed and maintained by DCMI did not suffice. In light of these additional requirements, AgMES created new properties and encoding schemes that constitute a namespace.

This element set is maintained by FAO at a stable location and identifies a reference point where elements are defined and are maintained to be used by different applications. The underlying RDF schema describing all the properties and schemes of the AgMES resources is accessible at http://purl.org/agmes/1.1/

3. Introduction and definitions

This section introduces a detailed specification for each term that constitutes the AgMES Namespaces. Each attribute, element, refinement and encoding scheme in AgMES semantics is expressed, where applicable, using properties as follows:

Name The formal name for the element.
URI The Uniform Resource Identifier used to uniquely identify the element.
Label The human readable label assigned to the element.
Definition A definition of the element based on the relevant definition for the element.
Comment A note providing information on the best practice of the element.
Refines An element of which the described term is a sub-element.
Qualifies An element of which the described term is qualifing.
