| Agricultural Metadata Element Set (AgMES) |
| The Agricultural Metadata Elements Project was set up to promote the use of metadata in description of all agricultural information resource types. Using carefully chosen metadata, which adopts standardized agricultural terms, will make it much easier to find and share information about those resources. In addition, the AgMES project is working to improve interoperability (e.g. capable of being implemented on multiple operating systems and in multiple programming languages) between, and among, uniquely and richly described agricultural information resources. The principal scope of the AgMES project is the successful integration and exchange of information for the benefit of everyone working in the agricultural domain. For more information, see: AgMES Homepage |

| AGRIS AP |
| AGRIS Application Profile. The AGRIS AP contains specifications about the meta data that should be exchanged and disseminated through the AGRIS system. An XML DTD for encoding of these metadata is included. These new guidelines can be used by AGRIS partners to contribute to AGRIS. Any XML document submitted following these specifications can be published through the AGRIS database on the Web and CDs. The specifications and the DTD should be stable for the entire year 2003. During the year we will collect feedback for the further improvement of the specifications; we will also be publishing an XML Schema and RDF schema for encoding of the records. See: http://www.fao.org/docrep/008/ae909e/ae909e00.htm |

| Application Profile |
| Application profiles are defined as schemas which consist of data elements drawn from one or more namespaces, combined together by implementers, and optimized for a particular local application. Application profiles follow the following four characteristics: - Draw upon existing pool of metadata definition standards to extract suitable and application or requirement oriented elements. An application profile can not create new elements. - Application profiles specify the application specific details such as the schemes or controlled vocabularies. An application profile also contains information such as the format for element value, cardinality or data type. - Lastly, an application profile can refine standardized definitions as long as it is "semantically narrower or more specific". This capability of application profiles caters to situations wherein domain specific terminology is needed to replace a more general one. |

| CODEN |
| Quite literally, CODEN stands for "Code Number." DEFINITION: "A system of alphanumeric codes developed by the American Society for Testing and Materials (ASTM ) to uniquely and permanently identify sci-tech serial and monographic publications. Responsibility for administering the system was transferred to Chemical Abstracts Service (CAS ) in 1975. The CODEN is used in electronic information systems to process bibliographic data because it is more concise than the full title and less ambiguous than an abbreviated title. |

| DTD |
| Document Type Definition. The purpose of a DTD is to define the legal building blocks of an XML document. It defines the document structure with a list of legal elements. The advantages of the DTD are many, viz. each of your XML files can carry a description of its own format with it; independent groups of people can agree to use a common DTD for interchanging data; your application can use a standard DTD to verify that the data you receive from the outside world is valid; and you can also use a DTD to verify your own data. |

| Hypertext |
| It is the fundamental notion behind the WWW, allowing one resource to be linked to other relevant information elsewhere on the WWW. This results in accessibility to information without a linear sequence as a user can jump from one website to another with only one click. It allows humans to access information in a manner similar to their non-sequential thinking process. |

| XML |
| eXtensible Markup Language. XML is the universal format for structured documents and data on the Web. It is designed to improve the functionality of the Web by providing more flexible and adaptable information identification. It is called extensible because it is not a fixed format like HTML (a single, predefined markup language). Instead, XML is actually a 'metalanguage' -- a language for describing other languages -- which lets you design your own customized markup languages for limitless different types of documents. XML can do this because it's written in SGML, the international standard metalanguage for text markup systems (ISO 8879). |
