GML parsing technology service and its sharing platform

GML (Geography Mark-up Language) has been adopted by ISO as standard for the transport and storage of geographic information, and it has been generally recognized by GIS researchers owing to its obvious advantages in these fields. However, most studies about GML are concentrated on its data description, exchange and representation etc. As GML is used in GIS application systems complexly and extensively, and related software tools and products are developed more and more, interoperation between GML applications technologies are becoming an outstanding obstacle that restricts their developments. As to the same application such as GML parsing, different users or GIS software can describe it differently when transferring their applications request through the web, which will result in semantic discrepancy and obstacle GML application technologies to share.
