1. Marine Metadata Interoperability - Web Services Marine scientists face an opportunity and a challenge in the volume of data available from various ocean observing systems. The MMI Project can help make it easier for you to find, access, and use other data sets. If you create marine science data sets, MMI can help make your data easier to advertise, distribute, reuse, and combine with other data sets. Our goal is to promote collaborative research in the marine science domain, by simplifying the incredibly complex world of metadata into specific, straightforward guidance. MMI hopes to encourage scientists and data managers at all levels to apply good metadata practices from the start of a project, by providing the best advice and resources for data management. MMI Mission Participating in the MMI Acknowledgements Ongoing funding for this project is provided by the National Science Foundation through grant ATM- 0447031. Major contributions to the project are being provided by SURA, the Southeastern Universities Research Association, and SCOOP, the SURA Coastal Oceans Observing Program, with funds provided in part by ONR, the U.S. Office of Naval Research. A significant bridge funding grant has been provided by NOAA's Coastal Services Center. Further support has been provided by the Monterey Bay Aquarium Research Institute and the David and Lucile Packard Foundation. The MMI promotes events, such as workshops and web conferences, for the advancement of cyberinfrastructure in the marine community. Our hundreds of members regularly participate in MMI activities. Data complexity and heterogeneity from observed data source in the MUSE Project http://www.mbari.org/MUSE/ “MMI Workshop: Advancing Domain Vocabularies”, Aug, 2005 Register and contribute to the site, participate in and/or co-host a workshop that teaches how to handle your kind of data, participate in the interoperability demonstration, test, provide feedback to, and contribute to our guides, participate in our help forum and publish and manage online documentation about your project in the MMI site. Please send an email to info@marinemetadata.org to get more information. Ontology Creation MMI is the liaison to bring community experts together to create controlled vocabularies and express them in the Web Ontology Language (OWL). These allows to clearly define the concepts and their relations, and to make inferences among them.
