Toward a Process Model for GI Service Composition

چکیده
The composition of individual web services to complex web service chains is a hot topic currently under discussion in the web community. Regarding the geospatial domain, the OpenGIS consortium has published a variety of standards and discussion papers that provide a model to chain geospatial web services. Put into action, it becomes obvious that the proposed model lacks some important features. It does not allow the integration of web services into higher abstraction levels or frameworks. No descriptive language is standardized to define complex chains and executable rules. The OGC discussion does not address semantic aspects at all. This papers aims at presenting concepts to overcome the above-mentioned deficits.
