OOSTethys Partners
Two grass-roots community initiatives have aligned to make some concrete choices that will advance the "system of systems" concept: the OpenIOOS Interoperability Test Bed (www.openioos.org), developed by SURA partners and the broader community, and the Marine Metadata Interoperability (MMI) Demo (www.marinemetadata.org). The combined initiative will leverage the complementary experiences that their partners bring to the table.
The first step to creating OpenIOOS.org occurred in 2004, when GoMOOS (www.gomoos.org) and SEACOOS (www.seacoos.org) deployed the first two OGC-compliant real-time data services that were aggregated and visualized at OpenIOOS.org. Within only a few months, the SOA demo grew to include several more OOSs and over a dozen university, non-profit and federal agency partners, including NOAA, NASA and Navy. Remarkable aspects of the demo include the heterogeneity of the underlying data systems, the highly distributed nature of these systems, and the variety of technologies used to implement the services, which include a combination of Open Source (e.g., University of Minnesota's MapServer) and commercial (e.g., ESRI) software. Integration and interoperability were achieved quickly and economically thanks to broad adoption of the OGC interface specifications.
The Marine Metadata Interoperability project started in September 2004. After almost two years it comprises more than 300 members, with a web site consisting of thousands of pages with guides and references about marine metadata issues. One of the activities of MMI is an interoperability demonstration using a service-oriented architecture, common use content standards, and semantic mediation via ontologies.
In 2005 MMI, OpenIOOS and SURA SCOOP started working together on a single, combined interoperability test bed activity that combines their programmatic interests of having distributed services and adopting a service-oriented architecture to share real time data. The two interoperability demonstrations were merged in June 2006 under the name of OOSTethys. The combined team set up an initial set of metadata requirements such as geo-spatial location and platform type, and agreed on an interface to serve as a wrapper for each data system.
- SURA - SURA is a consortium of over 60 research universities. With funding from the Office of Naval Research and NOAA, OpenIOOS participants have been demonstrating that "standards enable innovation" by leveraging web-service and data-model specifications developed by the Open Geospatial Consortium (www.opengeospatial.org). With support from the NOAA Coastal Services Center and the Office of Naval Research, the Southeastern Universities Research Association (SURA) has helped organize OpenIOOS.org as part of the SURA Coastal Ocean Observing and Prediction (SCOOP) program (http://scoop.sura.org). OpenIOOS.org, which is a proof of concept portal interface to the distributed participants, demonstrates a Service Oriented Architecture (SOA) with heavy emphasis on Open Geospatial Consortium (OGC) web-service specifications.
- MMI - With funding from NSF and NOAA, the MMI project has been enabling the exchange, integration and use of marine data by emphasizing ontologies based on the Web Ontology Language (OWL), in anticipation of the Semantic Web. MMI has also emphasized in Service Oriented Architecture demonstrations , by defining interfaces agreements via SOAP/WSDL and by defining metadata using an extension of Dublin Core
History of the partnership
OpenIOOS.org has been demonstrating that “standards enable innovation" for several years, thanks to contributions from Ocean Observing Systems (OOSs) around the country.The first step to creating OpenIOOS.org occurred in 2004, when GoMOOS (www.gomoos.org) and SEACOOS (www.seacoos.org) deployed the first two OGC-compliant real-time data services that were aggregated and visualized at OpenIOOS.org.
