Definitions: OGC and ISO 4.1.1 - service –distinct part of the functionality that is provided by an entity through interfaces [ISO/IEC TR 14252] 4.1.2- interface –named set of operations that characterize the behaviour of an entity 4.1.3 - operation –specification of a transformation or query that an object may be called to execute –NOTE An operation has a name and a list of parameters.

10. Helping the World to Communicate Geographically Copyright © 2008, Open Geospatial Consortium, Inc., All Rights Reserved. A Bit of Philosophy: OGC on SOA SOA is an architecture. That means it doesn't necessarily describe the technology involved in computing, but defines a framework which allows programs to interact. –Bob Breedlove, 2007 Hence, SOA is an Ecosystem: a space where people, machines and services inhabit in order to further both their own objectives and the objectives of the larger community. –Oasis 2008 SOA does not equal SOAP/WSDL

11. Helping the World to Communicate Geographically Copyright © 2008, Open Geospatial Consortium, Inc., All Rights Reserved. Service Architectures have been around for a while! 1989: GenaMap (Commercial GIS) –Used a services architecture (Request Broker, Service API based on secure sockets) 1991: Common Object Request Broker Architecture –Normalizing the method-call semantics between application objects that reside either in the same address space (application) or remote address space (same host, or remote host on a network) 1997: Enterprise Java Beans (EJB) specification –The EJB specification intends to provide a standard way to implement the back-end 'business' code typically found in enterprise applications (as opposed to 'front-end' user-interface code).

12. Helping the World to Communicate Geographically Copyright © 2008, Open Geospatial Consortium, Inc., All Rights Reserved.Assumptions More than ever, academia, institutes, government, and corporations engage in collaborative, complex applications. These applications require access to massive quantities of distributed, heterogeneous geospatial data, services, computing abilities and other facilities. Much of the content is being collected using sensors.

OGC Web Services First OGC Web Service was defined in 1998 First OGC Web Service Standard approved in 1999 We now have a suite of robust WS Standards OGC Standards are becoming an integral part of the evolving GeoWeb
