MMI: A Little Bit of Context John Graybeal

Monterey Bay Aquarium Research Institute Head of Marine Metadata Interoperability Project

Since 2004*, an international collaboration to address metadata issues

Goal is to help everyone solve their metadata problems Web site has resources, contributors, activities,

conference lists, project spaces…

The Paper

About Software CollaborationsWorst case: “Takeover” or “Forced Merge”

Goals poorly aligned Few shared technical perceptions Small steps prove impossible

Must build trust personally more than technically End of project (“big bang”) before visible result

Ambiguous and limited technical benefit

/ 6


Building Trust and Community Description of ideal collaboration

Shared goals and technical perspectives Trust grows incrementally, as does the product Clear benefits, few risks; often surprises are good

In this environment, collaboration thrives Success is likely, if good faith prevails Success feeds upon itself, creates more success Staff become eager to do more difficult projects

/ 8


Vocabularies as Team BuildersWhy focus on vocabulary development to

build major science collaborations? The ideal collaborative traits are all found in

vocabulary development Shared goals and technical perspectives Trust grows incrementally, as does work Clear benefits, few risks Positive surprises are likely

Result: Successful outcomes, teams ready to work on more challenging problems

/ 9


Supporting Evidence / Summary Several collaborations are developing along

these lines; others are proposed MMI itself Environmental Observatories in United States And others I can’t talk about…

Take-home message:For major projects that want to create a successful collaboration, start with vocabulary development.

How MMI Will Help Provide Resources and Community Create Tools and Best Practices Develop Interoperable Vocabularies

And teach others how to develop them

Provide Services via Web And demonstrate value finding science data

/ 12


Provide Resources and Community MMI Web Site: >500 references and guides

Pointers to Vocabularies, Standards, and Tools Recommendations about metadata issues Mail lists for expert help with any questions Conferences, workshops, proposal opportunities

Membership has its privileges 130 members have work space, better access Custom work areas for metadata-related projects Opportunities to contribute to international project

/ 13


/ 14


Create Tools and Best Practices Implementing tools to work with metadata

Easily map terms in different vocabularies Display similar terms from other vocabularies

Training scientists and developers Workshops focus on science domains Demonstrations use modern interfaces Training materials posted for everyone

Identifying best practices by other projects

Develop Interoperable Vocabularies(And teach others how to develop them!)

To deal with so many science vocabularies We have an interoperable architecture But we need to develop content: vocabulary maps

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

/ 18


Provide Services via Web(And demonstrate their use with science data.) 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

MMI Demo End-to-end use of

metadata to discover and use science data sets

Uses web services to map requests, find data

Many (and growing) participants

Take-Home Messages The Marine Metadata Interoperability Project

exists to help address scientific metadata challenges.

You can help guide, and grow, this international community-based effort. Please visit us, contact us, or become a member
