This Application Profile defines the metadata elements for exchanging information about events within the Agricultural Community. 

There is no DTD for this AP, as it is based on the RSS specification and extends it with event-specific elements and agriculture-specific schemes from the AgMES namespace.

The goal of this Application Profile is to define a standard exchange format for “basic” metadata about an organization. Metadata about an organization are a means to help identify regional, national and international organizations specializing in different agriculture-related domains.

The AGRIS Application Profile is a standard created specifically to enhance the description, exchange and subsequent retrieval of agricultural Document-Like Information Objects (DLIOs). It is a format that allows sharing of information across dispersed bibliographic systems and is based on well-known and accepted metadata standards.

The Bibliographic Ontology (BIBO) describe bibliographic things on the semantic Web in RDF. This ontology can be used as a citation ontology, as a document classification ontology, or simply as a way to describe any kind of document in RDF. It has been inspired by many existing document description metadata formats, and can be used as a common ground for converting other bibliographic data sources.

The objectives of the standard are to provide a common set of terminology and definitions for the documentation of digital geospatial data. The standard establishes the names of data elements and compound elements (groups of data elements) to be used for these purposes, the definitions of these compound elements and data elements, and information about the values that are to be provided for the data elements.

DCMI Metadata Terms is an authoritative specification of all metadata terms maintained by Dublin Core Metadata Initiative (DCMI) -- elements, element refinements, encoding schemes, and vocabulary terms (the DCMI Type Vocabulary).

Events Metadata Language (EventsML) is a new XML based standard the IPTC has started to develop. This standard is intended for exchanging information about the following subjects: Event publishing, Event planning, and Event coverage.

The Friend of a Friend (FOAF) project is about creating a Web of machine-readable homepages describing people, the links between them and the things they create and do.

The IEEE 1484.12.1 – 2002 Standard for Learning Object Metadata (IEEE LOM) is a data model, usually encoded in XML, used to describe a learning object and similar digital resources used to support learning. The purpose of learning object metadata is to support the reusability of learning objects, to aid discoverability, and to facilitate their interoperability, usually in the context of online learning management systems (LMS).

MARC 21 is a result of the combination of the United States and Canadian MARC formats (USMARC and CAN/MARC). MARC21 is based on the ANSI standard Z39.2, which allows users of different software products to communicate with each other and to exchange data.MARC 21 was designed to redefine the original MARC record format for the 21st century and to make it more accessible to the international community.

The Metadata Authority Description Schema (MADS) is an XML schema for an authority element set that may be used to provide metadata about agents (people, organizations), events, and terms (topics, geographics, genres, etc.). MADS serves as a companion to the Metadata Object Description Schema (MODS) to provide metadata about the authoritative entities used in MODS descriptions. The standard is maintained by the MODS/MADS Editorial Committee with the Network Development and MARC Standards Office of the Library of Congress and input from users.

The List of Multi-crop Passport Descriptors (MCPD) provides international standards to exchange passport information of accessions preserved in ex situ collections. These descriptors are in harmony with IPGRI crop descriptors lists and with those used under the FAO World Information and Early Warning System (WIEWS) on plant genetic resources. The revised version (December 2001) of the 1997 MCPD List includes a brief explanation of content, coding scheme and suggested fieldnames for each descriptor to assist in the exchange of this type of data.

Schema.org is an initiative launched on 2 June 2011 by Bing, Google and Yahoo! to introduce the concept of the Semantic Web to websites. On 1 November Yandex (largest search engine in Russia) joined the initiative.

The site schema.org provides a collection of schemas, i.e., html tags, that webmasters can use to markup their pages in ways recognized by major search providers. Search engines rely on this markup to improve the display of search results, making it easier for people to find the right web pages.

Many sites are generated from structured data, which is often stored in databases. When this data is formatted into HTML, it becomes very difficult to recover the original structured data. Many applications, especially search engines, can benefit greatly from direct access to this structured data. On-page markup enables search engines to understand the information on web pages and provide richer search results in order to make it easier for users to find relevant information on the web. Markup can also enable new tools and applications that make use of the structure.

FAO is establishing GIS guidelines and spatial standards and norms for internal use in order to rationalize, harmonize and advance its GIS and cartographic activities and to support GeoNetwork. At the same time several base maps are being developed with a number of partners for internal and external use.
