Interacting data services for distributed earthquake modeling

Abstract. We present XML schemas and our design for related data services for describing faults and surface displacements, which we use within earth-quake modeling codes. These data services are implemented using a Web ser-vices approach and are incorporated in a portal architecture with other, general purpose services for application and file management. We make use of many Web services standards, including WSDL and SOAP, with specific implemen-tations in Java. We illustrate how these data models and services may be used to build distributed, interacting applications through data flow
