11 November 2010. The Open Geospatial Consortium (OGC®) announces the formation of an OGC Web Services (OWS) Publish/Subscribe (PubSub) Standards Working Group (SWG). (http://portal.opengeospatial.org/files/?artifact_id=41513&version=1).
In many geospatial applications it is important to provide notification of events such as a sensor reading falling below a certain threshold or new data becoming available at a service. Often the events need to be known as soon as possible - for example in emergency management, early warning and monitoring applications. In these cases it is useful if clients can subscribe to a service that automatically sends a notice when an event of interest occurs.
Event publication and subscription has been the subject of considerable investigation in OGC testbeds, interoperability experiments and committee discussions. Various use cases have been studied that require the combination of OGC Web Service (OWS) standards and Information Technology (IT) standards that support publish/subscribe service functionality, such as OASIS Web Services Notification (WS-N) and ATOM.
Building upon a considerable body of experience and familiarity with the work that has been ongoing in other standards development organizations, the OWS PubSub SWG will develop an OGC standard that supports requirements for publication of and subscription to events in systems that implement OWS standards. The new OGC PubSub standard will define how established IT standards are to be used to enable publish/subscribe functionality in OGC services.
Project Charter Members include: International Geospatial Services Institute (iGSI) GmbH, National Center for Atmospheric Research (NCAR), Spot Image, University of Muenster - Institute for Geoinformatics (IfGI), Spacebel s.a., Botts Innovative Research Inc. (BIRI), METEO-FRANCE, UK Met Office, MIT Lincoln Laboratory, CubeWerx Inc., Galdos Systems Inc., and Northrop Grumman Corporation. Contact Johannes Echterhoff email@example.com for details.
The OGC is an international consortium of more than 400 companies, government agencies, research organizations, and universities participating in a consensus process to develop publicly available geospatial standards. OGC Standards support interoperable solutions that "geo-enable" the Web, wireless and location-based services, and mainstream IT. OGC Standards empower technology developers to make geospatial information and services useful with any application that needs to be geospatially enabled.
