Abstract: In order to manage fuzzy spatiotemporal XML data, several fuzzy constructs are integrated in XML documents. Consequently, Schema of XML documents need to be fuzzy spatiotemporal extended. In the meantime, the integrated constructs should be compatible by modifying Schema of XML documents. Fuzzy spatiotemporal XML data model was formally proposed firstly. Subsequently, Schema of the OID part, the ATTR part, the FP part, the FM part, and the FT part in fuzzy spatiotemporal XML data model were extended, respectively. In succession, an example was introduced to give illustrations. After extending Schema, the XML documents were compatible with fuzzy spatiotemporal information, which was easy to manage fuzzy spatiotemporal XML data. What’s more, it could be further used for representing, reasoning, and querying fuzzy spatiotemporal XML data.
