6.5.6 Invoke spatial data service services

From Geostandards

The INSPIRE Directive asks Member States in article 11(1) (e) to establish and operate a network of “services allowing spatial data services to be invoked”. In addition, where public authorities levy charges for invoke spatial data services, Member States shall ensure that e-commerce services (including rights management services) are available (arcticle 14(4)). The “Invoke Spatial Data Service” service allows defining both the data inputs and data outputs expected by the spatial service and define a workflow or service chain combining multiple services. It also allows the definition of a web service interface managing and accessing (executing) workflows or service chains. The “Invoke Spatial Data Services” service supports invoking individual (spatial) services as well as combinations of individual (spatial) services both synchronous and asynchronous, in service chains through a (web) service orchestration engine a.k.a. “workflow engine”. The service chains are expressed in a standard (e.g. XML-based) notation that can be consumed by commercial as well as open-source orchestration engines from multiple sources. For spatial data services available on the Internet, the “Invoke Spatial Data Service” service will enable a user or client application to run them without requiring the availability of a GIS. This requires that a client application can discover the service, bind to it and invoke it. The orchestration/combination of Spatial Data Service with other services will require to precisely define the interactions between the services. Therefore, the interaction between the (spatial) services to be invoked is defined as a workflow or composite service in a standard notation (e.g. XML-based).
