Abstract: Graphics configuration software for safe production management of agricultural products can effectively manage the production information of agricultural products. The issues of data exchange between multi-sources heterogeneous data and graphics were desired to be a key problem of graphics configuration software. The characteristics of information for safe production management of agricultural products was analyzed and abstracted，and then a XML-based description language was constructed. Configuration graphic interface exchanged data with XML documents that were regulated by this description language，but not directly with heterogeneous data sources. Thus, the differences of heterogeneous data sources were screened by applying this description language. The results showed that the method provides an effective solution for the problem of multi-sources heterogeneous data in the graphics configuration software for safe production management of farm product.
