  1. The Marine Metadata Interoperability ProjectOverview and Roadmap http://marinemetadata.org

  2. Aim(s) of the MMI Project Solve the metadata problem. Make data systems work together. Help users manage data using metadata. Improve data management and interoperability. Solve the“meta” part of the data interoperability problem. Marine Metadata Interoperability <http://marinemetadata.org>

  3. Aim of the MMI Project Solve the metadata problem. Marine Metadata Interoperability <http://marinemetadata.org>

  4. Aim of the MMI Project Solve the metadata problem. What does that mean? What metadata problem? Marine Metadata Interoperability <http://marinemetadata.org>

  5. The Metadata Problem: OneProtocols and Content Standards • All these systems working together. • How do they communicate? • Protocols • What do they talk about? • Content Stds Marine Metadata Interoperability <http://marinemetadata.org>

  6. The Metadata Problem: TwoSemantic Interoperability • Simple matter of language. Marine Metadata Interoperability <http://marinemetadata.org>

  7. The Metadata Problem: TwoSemantic Interoperability • Simple matter of language. And knowledge. Marine Metadata Interoperability <http://marinemetadata.org>

  9. “You Can’t Do That!” Solve the metadata problem. Actually, we think we can (or at least, come pretty close). Marine Metadata Interoperability <http://marinemetadata.org>

  10. How Will the MMI Project Do That? Solve the metadata problem. • Create and support a marine metadata community • A growing community of contributors and users • Establish a marine metadata information center • A place that has marine metadata answers • We can’t be totally expert, but we can know who is • Target the community’s technology needs • Guides; Vocabularies; Content Standards; Protocols; Tools; Demonstrations and Examples Marine Metadata Interoperability <http://marinemetadata.org>

  11. Community Web Sitehttp://marinemetadata.org • Easily navigate and locate content • Browse content to find useful standards and tools • Search for specific terms or descriptions • Find how-to information on using metadata • See comparisons of existing standards, tools Marine Metadata Interoperability <http://marinemetadata.org>

  12. Community Web Sitehttp://marinemetadata.org • Users can contribute their work and knowledge • Registered users easily create site content (plone) • Content approval and publication happens quickly • Example: Support for domain vocabulary efforts • MMUG metadata workshop working groups • Environmental Observatories Data Mgt Collaboration • MBARI Standard Naming exercise • COTS development (tbd) Marine Metadata Interoperability <http://marinemetadata.org>

  13. Mailing Lists • Public lists (ask@marinemetadata.org) • Think of this service as free consulting • Should serve, stimulate, and engage community • Open to any inquiries; moderated as needed • Others: news@marinemetadata.org (newsletter), workshop05-news@marinemetadata.org (workshop info) • MMI-internal lists Marine Metadata Interoperability <http://marinemetadata.org>

  14. Lots of Public Outreach • Meetings • Conference presentations • Attendance and support at conferences • Email • Announcements on other lists • Announce our latest services on our own list • Links from other sites • May consider collaborations with some sites • Documents and handouts Marine Metadata Interoperability <http://marinemetadata.org>

  15. “That Won’t Be Enough.” Solve the metadata problem. But wait! There’s more! Marine Metadata Interoperability <http://marinemetadata.org>

  16. Metadata Projects • Metadata-Centric Interoperability Demo(MBARI wanted this) • Scientific Domain Vocabularies Work(Some in MMI wanted this) • Workshop (We needed one) • Web Services (The next thing for LOOKING) Marine Metadata Interoperability <http://marinemetadata.org>

  22. Vocabulary Web Services Marine Metadata Interoperability <http://marinemetadata.org>

  23. Metadata Demonstration 1) Vocabulary Harmonization 2) Vocabulary Mapping 3) Vocabulary Services 4) Access to Data Marine Metadata Interoperability <http://marinemetadata.org>

  24. Is That It?(Yes and No.) Solve the metadata problem. • We will map and publish a few vocabularies. • The “side effects” are valuable • Documented processes, training, and tools. • Common, central access to many vocabularies. • Functional services useful in applications. • Possibly, a standardized semantic framework. • Community of metadata-aware domain experts. Marine Metadata Interoperability <http://marinemetadata.org>

  25. Longer-Term Activities • Get more visitors, members (100), contributors • Demonstrate usable results and systems • Hold 2005 Marine Metadata Workshop • Will harmonize domain-specific ontologies • Will entrain multiple small groups (experts in each) • Address governance issues • This is (hopefully!) a long-term community activity • Get funding! Marine Metadata Interoperability <http://marinemetadata.org>

  26. Prognosis • Technical • Talented people starting to create useful products • Big world with lots of needs—what should we fill? • Funding • One-Year Program (through September 2005) • Prospects for finding money decent, but not definite • Organizational • Need to create sustaining governance and financing • For external communities, MMI might be example, consultant, or member organization, as appropriate Marine Metadata Interoperability <http://marinemetadata.org>
