The <strong>Marine</strong> <strong>Metadata</strong><br />
<strong>Interoperability</strong> Project<br />
A Model for Community Collaboration<br />
September 23, 2010<br />
Nan Galbraith<br />
WHOI
Mission<br />
"Promoting the exchange, integration and use<br />
of marine data through enhanced data<br />
publishing, discovery, documentation and<br />
accessibility.”
Goals<br />
• Support collaborative research<br />
• Provide guidance on metadata practices<br />
• Identify and describe existing standards, tools<br />
• Develop tools and services when needed<br />
• Community outreach and engagement
MMI Participants<br />
• Workshop Planning – TAMU<br />
• Website Development – WHOI<br />
• <strong>Metadata</strong> <strong>Guides</strong> – SDSC (SIO)<br />
• Technology and Services – MBARI<br />
• <strong>Interoperability</strong> Demonstration – SURA, IOOS<br />
• Strategic Planning - MBARI<br />
Funded by NSF, SURA, NOAA
Main MMI Projects<br />
• Website: Resources & References<br />
• <strong>Metadata</strong> <strong>Guides</strong><br />
• Ontology Development<br />
– Ontology Registry and Repository<br />
• OOSTethys Demonstration Project
Website: Web Resources & References<br />
• Documenting existing standards, tools etc.<br />
• Emphasis on user-supplied content<br />
– Lots of volunteer labor<br />
– Team approach<br />
• Constant feedback from users<br />
– User testing, surveys, analytics
Website: Community Building<br />
• Provided workspace for groups<br />
– External and within MMI<br />
– Integrated email services, group documents...<br />
– Varied success with external groups<br />
• Used Plone and then Drupal (CMS)
Website: Community Building
<strong>Metadata</strong> <strong>Guides</strong><br />
• Web-based textbook (Drupal “book”)<br />
• Readable metadata information<br />
• Basic principles, best practices<br />
• Options for documenting and sharing data<br />
• Authored by <strong>Guides</strong> Team, 11 co-authors
<strong>Metadata</strong> <strong>Guides</strong>: Contents<br />
• Introduction to <strong>Metadata</strong><br />
• <strong>Metadata</strong> Standards<br />
• Vocabularies: Dictionaries, Ontologies<br />
• Technical Tools<br />
• Case Studies<br />
• Interactive Dictionary
Ontology Work<br />
• Document existing ontologies<br />
• Create mapping tools<br />
• Develop ontologies where needed<br />
• Hold workshops<br />
– vocabulary mapping exercises<br />
• Work with existing groups<br />
– SWEET, OGC, W3C
Ontology Development<br />
• Platform Ontology<br />
– Stable, if not complete, possibly best available<br />
– Available on MMI ORR<br />
• Device Ontology<br />
– Thorough model of attributes of data sources<br />
– Grew out of a 2005 mapping workshop<br />
– In development, but available on ORR
MMI Ontology Registry<br />
and Repository<br />
• Serves environmental science vocabularies<br />
• Supports cross-community use of terms<br />
• Leverages MMI’s library of semantic resources<br />
• Built on BioPortal (National Center for<br />
Biomedical Ontologies)
MMI Ontology Registry<br />
• Ease of input a priority<br />
– User-input CSV to automatic network updates<br />
• Currently 153 vocabularies<br />
– Each term has unique URI<br />
– Versioning enabled<br />
• Associated semantic framework<br />
– infrastructure (tools, processes)
Sample Vocabulary <strong>Metadata</strong>
Sample Vocabulary Versions
Sample Vocabulary – RDF View
<strong>Interoperability</strong> Demonstration<br />
OOSTethys<br />
• Provides users fast data publication<br />
• Test bed for Semantic Framework<br />
• Collaboration with SURA<br />
• Next, working with OGC on Oceans IE
The <strong>Marine</strong> <strong>Metadata</strong><br />
<strong>Interoperability</strong> Project<br />
What are our results<br />
How do we judge our success<br />
What’s next for the project
MMI Results<br />
• 453 members (> 300 active in last 2 years)<br />
• > 100 presentations & posters<br />
• > 4,600 documents on website<br />
• 153 ontologies registered on ORR<br />
• Hosted several workshops, tutorials
MMI Results<br />
• Engaged domain scientists,<br />
technologists, data managers<br />
• Involved most major US marine science<br />
institutions & many agencies<br />
• Attracted some international<br />
participation<br />
• Lots of volunteer labor
MMI Results<br />
• Many groups produced lasting products<br />
• Required intense commitment of PI<br />
• Major challenge: long term funding<br />
– Longevity is critical for community projects<br />
– Really crucial for ORR<br />
– Difficult (and important!) for volunteers
