2003: Marine Metadata workshop (S Watson)
MMI: A Brief History
2004: MMI proposal, award, web site
MMI: A Brief History
2005: Hire, tools, workshop, 2nd proposal
MMI: A Brief History
2006: NOAA & 2nd NSF awardsOOSTethys prototype, OGC participation
Involvement in ORION, IOOS data committees
Increased international participation
More funding and distribution of US participation

MMI: You Are Here
Doing Science: The Way It Has Been Done
Hey Francisco, you still running that mooring in Monterey?Yeah, John, what do you need?Yeah, John, what do you need?
Is it collecting current data?Yeah, you looking for profiles?Yeah, you looking for profiles?
Yup, are you doing that with an ADCP?Yes, we’ll probably start profiling soon, too.Yes, we’ll probably start profiling soon, too.
No, don’t need that. How do I get the data?You want the raw data or QCd? Real-time?.You want the raw data or QCd? Real-time?.
Oh, the QC’d, delayed mode data, definitely, last 3 years worth.That’d be off our dods site, here’s the address..That’d be off our dods site, here’s the address..
Documentation come with that?We got some, I’ll have to get one of my techs to send it to you…We got some, I’ll have to get one of my techs to send it to you…

Big Picture: ORION
What Will It Take?
(from ORION Cyberinfrastructure Concept of Operations)
What will it take for a science researcher to access all the data from MBARI, NDBC, and ORION, assess the data that is useful for his or her project, bring it into an analysis program, and produce the first visualization all in a single day, and still have time to call one of the data producers and ask about the details of the latest quality control process?
What It Will Take
Communities Creating Marine Data and
Metadata Interoperability
What’s needed for marine metadata interoperability?
Several areas of community agreement.
• The way to transfer the metadata:Transport Protocol
• What data to transfer: Content Standard
• What the contents mean: Vocabulary

We have some of these—so where’s the problem?

Identifying technical gaps—Vocabularies
• Few formal marinevocabularies existed
• There was no agreed format or location
• Most weren’t comprehensive or detailed• There was no way to connect them• There was no architecture to nurture them
– Like children, they need encouragement to grow healthy and strong, and to play well with others

International Challenges
• Technical Needs– Address a Range of Sophistication– Leverage Existing Technologies– Provide Localization
• Cultural Challenges– Language– Nationality
• Making Collaborations Valuable
MMI Strategies for International Success
For Any Collaboration Problem—There Are 3 Options
• Create a committee to develop (or anoint) a consensus standard
• Find a wizard (or giant) who will create a compelling standard
• Build translators

• ARPANet: new endpoint-oriented protocol– Worked really well, so everyone built one– BUT! None of them worked with each other

Sensor Metadata Interoperability Workshop
• October 19-20, 2006 in Portland, Maine
• Learning about sensor metadata content standards
• Unknown if any anointing will occur!
