AB: Ocean observing systems incorporate a spectrum of sensors and data. Making the data available to any interested scientist is important: data sharing and experimental reproducibility are hallmarks of the scientific process. However, different groups may represent, transport, store and distribute their data in different ways, leading to difficulties in sharing these data. OOSTethys, an open-source community effort with involvement from six regional associations and two major research institutes, is exploring the best mechanisms to make ocean data and metadata interoperable by advancing and influencing standards from the Open Geospatial Consortium (OGC), World Wide Web Consortium (W3C) and OASIS. Our strategy to address these challenges has been to envision a service oriented architecture (SOA) which comprises data providers, registries, semantic mediators, aggregators and visualizers. For each component of the system we select the most appropriate standard(s) and create cookbooks and tools to support its implementation. This improves accessibility for data providers with limited time and limited budgets for information technology projects. For example, we have created cookbooks and toolkits in Perl, Java and Python to facilitate implementation of OGC Sensor Observation Services (SOS). The implementation includes publishing metadata in SensorML, and making data available via Geographic Markup Language (GML) records conforming to the Observation and Measurements specifications. A semantic mediator implemented as a web service uses Semantic Web technologies to solve semantic incompatibilities, and enables proper categorization of the different services. Our initial results are positive: in addition to several national demonstrations of data interoperability, the cookbooks have been used to bring more than 60 oceanographic platforms online, and we have at least 7 data consumers relying on web services for their own oceanographic applications. OOSTethys work is an essential part of the OGC's Ocean Science Interoperability Experiment, which seeks more participation from the Geospatial community to advance data interoperability in Ocean Observing Systems.
