My research interests originated from using Web service technology for GIS (Geographic Information Systems) applications. So my examples are domain specific but may be valuable to promote advancement in this promising research direction. One core problem is the vector geospatial features (points, polylines, polygons) are described in an XML document. Given the following examples, http://157.182.136.51/agswsprojs/geoWebService/Service1.asmx http://157.182.136.51/agswsprojs/geoWebService/Service2.asmx http://157.182.136.51/agswsprojs/geoWebService/Service3.asmx http://157.182.136.51/agswsprojs/geoWebService/Service4.asmx How can OWL-S and WSMO describe the meaning of such services since all the input geospatial features are contained in an XML document? What you know from WSDL file is only the "name" of the document other than the meaning and content? A typical case of such XML document for geospatial features is the GML (Geographic Markup Language). In case 4, even the order of input features has to be specified meaningfully otherwise the result will be completely wrong. I suggested a new approach for building semantic Web services which may provide an alternative way that can be applied for every different service domains. The paper was published in the 2nd SDWP workshop proceedings and this paper may help to answer your question on "Can we build more self-explainatory application with more explicit semantics?" as it can solve the same problems in the GIS domain. Your critical comments and suggestions will be greatly appreciated.
