The Study on the Organization Approach of Agricultural Model Components Library Based on Topic Map

The definition and representation on the model base’s descriptions are the basis of reuse, integration and management of heterogeneous model resources. The study proposed the organization method of the agriculture model component based on topic maps. On the basis of the meta-modeling techniques and the topic map techniques, the study comprehensively analyzed the agricultural model characteristics, extracted the model component facets and its associated descriptions, and established the agricultural model component library’s description model (DM-AMCL). Then, it hierarchically mapped and annotated the model component semantic and syntactic information by using the topic map. We designed the organization framework of the agriculture model component library on topic maps (TM-AMCL). For example of wheat development model, the XTM document instance is build. The result shows that, converting the agriculture models base to TM-AMCL can provide a unified descriptions and access to data for the intelligent decision support system developers, the managers of agriculture model and the computer system.
