Overview• Background

• Nature of the challenge• Previous work• Original proposal

• Status• Community building and outreach• Vocabulary work• Demonstrations


5

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?


6

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


7

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


10

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


14

VINE tool for mapping between vocabularies

Workshop Goals

• Domain leads (common)

• Domain leads (unique)

• MMI project


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


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


20

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
