A Topic in the Meta Knowledge Base is a collection of profiles and postings related to a specific subject. Topics works very much like "favourites" in your browser, as it is way to easily store interesting items for later use. Topics can have an attributed text providing, for example, a review of the knowledge within the specific subject.
Users can create their Private Topics by using the links in the left hand menu after login.
A Public Topic must have a dedicated editor, who will actively invite researchers and developers to write postings related to the topic, and who will maintain an updated review of the topic. Public Topics are acknowlegded by the Meta Knowledge Base administration. Potential editors should send a mail to Webmaster.
Topics will also be a tool for ICT-AGRI to collect relevant information.
Weather data for agrometeorological applications The purpose of this topic is to gather knowledge about formats for the exchange of weather data for agrometeorological applications, to discuss the applicability of different formats, and ultimately to achieve acceptance of a common format.

Agrometeorological applications are an important in Decision Support Systems for irrigation, crop protection and other weather dependant agricultural activities. Although similar kinds of weather data are used in all applications, there are no widely accepted standard for the exchange of weather data within the agricultural domaine. It is therefore cumbersome to export agrometeorological applications to new agricultural domains. The usual architecture of agrometeorological applications combines a decision engine with a weather database. It takes quite a lot of resources to maintain a constantly updated and error free weather database, which adds considerably to operating costs. Furthermore, data definitions and naming conventions are normally not standardised, making it difficult to export or import applications. A better solution would be to run the decision engine and the weather database as two dispatched applications with on-the-fly supply of weather data to the decision engine for a given task upon request. The maintenance of weather databases could then be left to professionals, for example meteorological institutes and organsiations operating weather stations for agricultural purposes. The Service Oriented Architecture (SOA) offers very attractive methods for supplying customers with data upon request based on web services. An example is described in Posting 94
