Website: Community Building Provided workspace for groups –External and within MMI –Integrated email services, group documents... –Varied success with external groups Used Plone and then Drupal (CMS)
Metadata Guides: Contents Introduction to Metadata Metadata Standards Vocabularies: Dictionaries, Ontologies Technical Tools Case Studies Interactive Dictionary
Ontology Work Document existing ontologies Create mapping tools Develop ontologies where needed Hold workshops –vocabulary mapping exercises Work with existing groups –SWEET, OGC, W3C
Ontology Development Platform Ontology –Stable, if not complete, possibly best available –Available on MMI ORR Device Ontology –Thorough model of attributes of data sources –Grew out of a 2005 mapping workshop –In development, but available on ORR
MMI Ontology Registry and Repository Serves environmental science vocabularies Supports cross-community use of terms Leverages MMI’s library of semantic resources Built on BioPortal (National Center for Biomedical Ontologies)

The Marine Metadata Interoperability Project What are our results? How do we judge our success? What’s next for the project?
MMI Results 453 members (> 300 active in last 2 years) > 100 presentations & posters > 4,600 documents on website 153 ontologies registered on ORR Hosted several workshops, tutorials
MMI Results Engaged domain scientists, technologists, data managers Involved most major US marine science institutions & many agencies Attracted some international participation Lots of volunteer labor
MMI Results Many groups produced lasting products Required intense commitment of PI Major challenge: long term funding –Longevity is critical for community projects –Really crucial for ORR –Difficult (and important!) for volunteers
