Exemple : Presentation Service
Presentation Service (portrayal) is a rendering engine that should support different types of rules and delivers a map as result :
– These rendering rules are customisable via the StyleEditor.
– The output formats JPEG, PNG, GIF, BMP, WBMP, GeoTIFF and SVG are supported

In SOA Architecture…
Everything is a Service (data, metadata, access, functions, catalogs, …)
Every service describes itself, exposing its semantic Content & services are registered in a Catalog Services can be easily found, with semantic User understand what the service is offering When found, binding to service is automatic
(subject to security check)
User expected result is delivered (“certified or trusted” service)
Optionally, User pay to use a service

SOA, Web Service & InteropRules
Define semantic of data and of data types Design or map to an interoperable data model /
schema Adopt standard encoding (XML-based) Define semantic of services Respect Interfaces (standard!!!) Expose interfaces & semantic of services Use metadata to describe :
– Service interface & protocol,– Service characteristics, – Data served, – Usage & semantic, – …
Register in a Catalog Service
In geospatial, hundreds of man-years have been necessary to define interop standard and achieve consensus Use it !

Advantages of SOA - Costs & Effectiveness
Distributed Architecture, subject to security check (dynamic “publish – find – bind”)
Facilitate organizational decisions : clear responsibility
Optimize information exposure and decision support
Avoid data replication, costly and easy-outdated = huge optimization of data conversion costs
Reduction of integration costs
Save time : access faster to right information
More applications possible as more views on information
Same access method inside and outside the Enterprise, based on open interfaces (abstraction vs implementations)

Conclusion
SOA allow to develop faster more powerful applications with less costs (interchangeable & reusable)
With SOA, Geospatial interoperability delivers more value at lower costs
SOA opens new horizon & challenges
SOA allows to formalize a federating framework to develop interoperable system at organization level but also across organizations
… and all players take benefit of it !
