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

2 LOOKING 2005.05.17Marine Metadata Interoperability 1 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.

3 LOOKING 2005.05.17Marine Metadata Interoperability 2 Aim of the MMI Project Solve the metadata problem.

4 LOOKING 2005.05.17Marine Metadata Interoperability 3 Aim of the MMI Project Solve the metadata problem. What does that mean? What metadata problem?

5 LOOKING 2005.05.17Marine Metadata Interoperability 4 The Metadata Problem: One Protocols and Content Standards All these systems working together. How do they communicate? Protocols What do they talk about? Content Stds

6 LOOKING 2005.05.17Marine Metadata Interoperability 5 The Metadata Problem: Two Semantic Interoperability Simple matter of language.

7 LOOKING 2005.05.17Marine Metadata Interoperability 6 The Metadata Problem: Two Semantic Interoperability Simple matter of language. And knowledge.

8 LOOKING 2005.05.17Marine Metadata Interoperability 7 The Metadata Problem: Two Semantic Interoperability Simple matter of language. And knowledge.

9 LOOKING 2005.05.17Marine Metadata Interoperability 8 “You Can’t Do That!” Solve the metadata problem. Actually, we think we can (or at least, come pretty close).

10 LOOKING 2005.05.17Marine Metadata Interoperability 9 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

11 LOOKING 2005.05.17Marine Metadata Interoperability 10 Community Web Site http://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

12 LOOKING 2005.05.17Marine Metadata Interoperability 11 Community Web Site http://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)

13 LOOKING 2005.05.17Marine Metadata Interoperability 12 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

14 LOOKING 2005.05.17Marine Metadata Interoperability 13 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

15 LOOKING 2005.05.17Marine Metadata Interoperability 14 “That Won’t Be Enough.” Solve the metadata problem. But wait! There’s more!

16 LOOKING 2005.05.17Marine Metadata Interoperability 15 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)

17 LOOKING 2005.05.17Marine Metadata Interoperability 16

18 LOOKING 2005.05.17Marine Metadata Interoperability 17 Our Model

19 LOOKING 2005.05.17Marine Metadata Interoperability 18 DTD CommaSeparatedValues HTMLTabSeparatedValues RelationalDatabase XML/XSD RDF Vocabulary Harmonization

20 LOOKING 2005.05.17Marine Metadata Interoperability 19 DTD CommaSeparatedValues HTMLTabSeparatedValues RelationalDatabase XML/XSD RDF OWL Vocabulary Harmonization

21 LOOKING 2005.05.17Marine Metadata Interoperability 20 Vocabulary Mapping Alignment Mapping Source: Mena, E., Kashyap, V., Illarramendi, A. and Sheth, A. (1996). Managing multiple information sources through ontologies: relationship between vocabulary heterogeneity and loss of information. Knowledge Representation Meets Databases, Proceedings of the 3rd Workshop KRDB'96, Budapest, Hungary, Technical University of Aachen.

22 LOOKING 2005.05.17Marine Metadata Interoperability 21 Vocabulary Web Services

23 LOOKING 2005.05.17Marine Metadata Interoperability 22 1) Vocabulary Harmonization 2) Vocabulary Mapping 3) Vocabulary Services 4) Access to Data Metadata Demonstration

24 LOOKING 2005.05.17Marine Metadata Interoperability 23 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.

25 LOOKING 2005.05.17Marine Metadata Interoperability 24 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!

26 LOOKING 2005.05.17Marine Metadata Interoperability 25 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

27 LOOKING 2005.05.17Marine Metadata Interoperability 26 Credits National Science Foundation 1 SURA, the Southeastern Universities Research Association (http://www.sura.org),http://www.sura.org ONR, the Office of Naval Research (http://www.onr.navy.mil),http://www.onr.navy.mil NOAA (including the Coastal Services Center), OceanUS and regional IOOS systems. 1 NSF Grant ATM-0447031

28 LOOKING 2005.05.17Marine Metadata Interoperability 27 Sample Screen Shots The system evolves, so these screen shots do not represent the current site format.

29 LOOKING 2005.05.17Marine Metadata Interoperability 28 Demonstration

30 LOOKING 2005.05.17Marine Metadata Interoperability 29 Demonstration: Search for Content

31 LOOKING 2005.05.17Marine Metadata Interoperability 30 Demonstration: Add Document

32 LOOKING 2005.05.17Marine Metadata Interoperability 31 Demonstration: Create Content

33 LOOKING 2005.05.17Marine Metadata Interoperability 32 Demonstration: Finish Content

34 LOOKING 2005.05.17Marine Metadata Interoperability 33 Demonstration: View Results

35 LOOKING 2005.05.17Marine Metadata Interoperability 34 How We Do Work: The Technical Team Core contributors with site responsibilities Some are paid, many volunteer Located throughout the world Some are from Steering Committee (experts!) Sub-teams work on each area of site Review and edit your contributions Maintain consistent look and feel overall Coordinate amongst selves, and with MMI Liaison MMI Liaison and PI facilitate progress

36 LOOKING 2005.05.17Marine Metadata Interoperability 35 How We Make Decisions Background MMI asked to rise to this challenge Fairly smooth operational structure in place (small) Community has large role in setting our direction Organization and content of site community-driven Participation needed from all sectors Goal: Inclusive, open, efficient decision-making
