Challenge• Not a new problem in managing data
• How do we know what this data is?
• Increasingly large volumes of data gathered in short time periods• How can we make things automatic?
• Search, transfer, retrieve, evaluate, aggregate…• How to interoperate between data systems?
• Multi-disciplinary work increasing• How do we make the meaning of data from one domain
clear to someone working in a different domain?

Previous work
• Many different standards, conventions, approaches, tools being developed• Lots of resources being spent
• Many activities are program- or project-specific
• Precursors to the MMI• Marine Mapping Users Group Workshop - October, 2003
• ArcGIS Marine Data Model - identification of different marine data types

Original Proposal• 1 year of NSF funding ($400K) ATM-0447031
• John Graybeal, MBARI, lead PI• Builds upon previous activities
• Encourages community involvement and takes advantage of significant, existing expertise
• Provides guidance and centralized reference documentation
• Uses test-bed activities to demonstrate interoperable, distributed systems
• Involves Steering Committee from a diversity of government agencies and academic institutions

Goals of the MMI Project
Help users manage data by using metadata.Help users manage data by using metadata.• Establish a marine metadata information center
• A place to start for marine metadata answers• We can’t be completely expert, but we can know who is
• Engage and support marine metadata community• A rapidly growing community of contributors and users
• Contribute to community’s technology needs• Guides; Specifications; Vocabularies; Protocols; Tools;
Demonstrations and Examples

Community Building and Outreach: Status
• Over 150 registered users on website/lists• Work space, better access to information• Custom work areas for metadata-related projects• Opportunities to contribute to international project
• > 500 references and guides on website• Pointers to Vocabularies, Standards, and Tools• Recommendations about metadata issues• Mail lists for expert help with any questions• Conferences, workshops, proposal opportunities
• Presentations at workshops/conferences• 50 participants in the 1st MMI workshop

Vocabulary Work: Status
• To deal with so many science vocabularies• We have an interoperable architecture• But we need to develop content: vocabulary maps
• Formalize vocabularies in OWL• Map between vocabularies to discover terms that are same as,
broader than, narrower than (more later)
• Vocabulary mapping workshop(s)• Domain experts map the terms for their domain• MMI provides tools, technologists to make it easy
• First workshop: Boulder, Colorado (Aug 9-11)• 4-6 domains; 6-8 in each group• See http://marinemetadata.org/workshop for details• All results will be posted on web site

13
Vocabulary Work: Status• Information stored as OWL representation
• Ontological Language for the Web; relations in XML
• Web services “publish” vocabularies/maps• Applications use the web services
• Look up terms and relationships• Find data sets which use those terms and
relations• Get data from those data sets

Workshop Goals
• Domain leads (common)
• Domain leads (unique)
• MMI project
2005.03.23 Marine Metadata Interoperability <http://marinemetadata.org>
18
Common Domain Goals
• Define the domain
• Identify vocabularies of interest
• Map many terms
• Find a preferred or common vocabulary• “Publicly documented, web-accessible, reasonably
well organized and comprehensive, and has some level of community acceptance”
• Identify a maintenance process
2005.03.23 Marine Metadata Interoperability <http://marinemetadata.org>
19
Unique Goals
• “Find a common vocabulary” not unique
• Identify remaining challenges
• Demonstrate discovery of hidden datasets
• Allow data mapping between divisions
• Consider a wider context of related issues
• Build a community of professionals dedicated to making progress

MMI Project’s Workshop Goals
• Hold a community workshop!
• Define “the metadata problem” better
• Develop strategies to address it
• Get domain scientists involved
• Get solution providers involved
• Give people a real taste of progress• Immediate and ongoing benefits
• Long term direction, vision, and opportunity
