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?
Is it collecting current data?
Yeah, you looking for profiles?
Yup, are you doing that with an ADCP?
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?.
Oh, the QC’d, delayed mode data, definitely, last 3 years worth.
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…

Big Picture: ORION
What Will It Take?
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?
(from ORION Cyberinfrastructure Concept of Operations)
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
Transport Protocol
• What data to transfer:
Content Standard
Content Standard
Vocabulary
• What the contents mean:

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

Identifying technical gaps—
Vocabularies
BODC
TEMP
GCMD
• Few formal marine
vocabularies 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

• Vocabulary INtegration Environment
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

– Worked really well, so everyone built one
– BUT! None of them worked with each other

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