We propose moving objects data model and its query language over GML documents. The conventional query languages about GML have been studied with priority given to the integration of geographic information, the support of spatial operations, etc. However, it lacks the support for moving object queries. Therefore, in this paper, we propose the moving objects query language that supports moving object queries for GML documents by extension of XQuery that is standard XML query language. Also, data model, algebra operation and various moving objects operators for the proposed query language are designed.
