+ SNS German Environmental Information Network > 200.000 individual web pages supplied by over 80 authorities + > 500,000 objects in 9 remote databases Semantic Network Services Harmonize environmental information from national and state authorities
The gein® Integrated Ontology Bi-lingual German/English • a thesaurus of currently 39,143 environmental terms (UmThes®, German source of GEMET) • a gazetteer including the intersections between 48,213 geographical objects of all kinds (extended GN250, includes UN LOCODE); • a chronology of historical and contemporary events that have affected the environment, currently 544 events. Before SNS, these were three distinct ontologies.

What happened since Chernobyl? Accident at the Chernobyl reactor ??? Following a fire and minor explosion in one of the four reactors in the Ukrainian atomic power station Chernobyl, 10,000 km2 of the surrounding area is contaminated radioactively, affecting 640 communities and 230,000 inhabitants. There are 35 immediate fatalities, and opinion is still divided as to the extent of the long-term consequences. 1986-04-26

WS Versus Past EAI Technologies • Global scale • WS has a global architecture, infrastructure (e.g., DNS and the Internet) and support organization in place. • Simplicity • Conceptually simple. Simple to ‘bolt-on’ to existing infrastructures (e.g., EJB, CORBA, COM, …) • Loose coupling • WS is an interface/protocol: • WS does not force an implementation model • No need for administrators to establish connections between groups. • Implementation encapsulation: Does not directly operate on objects. Interfaces less brittle. • The result is industry buy-in • Backed by Microsoft, IBM, and the Java community, … as well as middleware and packaged applications.
WS for SNS • Global scale • SNS WS enables 80 environmental authorities to exploit and provide the ontology, classification, and indexing services using existing infrastructure • Simplicity • Local authorities can join when and to the degree desired • Loose coupling • Local authorities do not need to rewrite legacy systems • Services approach means that they don’t have to expose implementation details, use unfamiliar implementation techniques • The result is buy-in
Conclusion • SNS allows active usage of the ontology for any network member; • Avoids multiple platform support and physical distribution of the ontology server application; • Enables local database search methods to understand the topics to search for (in the gein® context); • Provides the shared ontology to local Intranets and regional public information systems.
