The CLAFIS Information processing and Knowledge management Module (IPKM) has been developed in WP4. This module applies novel principles for agricultural information and knowledge management, including data security, privacy and authentication, which will allow new possibilities for agronomic modelling, decision support and predictions.

The CLAFIS IPKM platform facilitates information retrieval/extraction as well as for the purpose of data linking and connectivity; harvesting and fetching; integrated processing, monitoring and control; and knowledge management (KM); including algorithms and APIs, and data storage system for data pool, process automation and control. In the IPKM platform, three Key Exploitable Results (KER’s) were facilitated: Knowledge Processing Framework (KPF), Data Fusion Framework, and the Central Authentication and Authorization System (CAAS).

In the Knowledge Processing Framework (KPF), the following modules were implemented:

• Knowledge Extraction Module: Prototype for Chemical Documents, Extraction- and Search-Functionalities for PDF Documents
• Plant Protection Module: Calculation of Disease Pressure, Disease Pressure Model from LUKE and DACOM
• Cereal Maturation Module: Cereal Maturation Formula developed by LUKE

Detailed information about the Knowledge Processing Framework (KPF) can be accessed here.

 

The Data Fusion Framework is used for raw data, that is obtained directly from the sensors and the term information fusion is employed to define already processed data, which means that the term information fusion implies a higher semantic level than data fusion does. The received climate date from LUKE is extracted as XML file and afterwards parsed and embedded with C to be run in the CLAFIS cloud.

So the whole system works, many individual components need to communication within CLAFIS. Here, safety and security are important issues. On one hand, costly information should not be disclosed to unauthorized people, on the other hand each component must be able to rely on the information it receive to be correct. To ensure this, a Central Authentication and Authorization System (CAAS) has been developed for CLAFIS. The system consists of independent servers. One or more Authentication-Servers verify the identity of the users and the Authorization-Server maintains information about what rights a user has for specific resource. In the following diagram, the communication between the different components of the CAAS can be seen.
