1 The MMI Workshop Advancing Domain Vocabularies August 9-11, Boulder, Colorado

2 2005.03.23Marine Metadata Interoperability 1 Welcome & Introductions Welcome to a Working Class Workshop Thank Yous Luis Bermudez Stephanie Watson (Matthew Howard) The Leads: Roy Lowry (Chlorophyll and Pigments) Bob Arko (Sensors) Cyndy Chandler (CTD and all that) Jerome King (PaCOOS) Mark Costello/Karen Stocks (Benthic…Habitat?) Julie Thomas (Winds and Currents)

3 2005.03.23Marine Metadata Interoperability 2 Logistics Bathrooms Wireless Parking Dinners Tonight: Head Count Tomorrow Night: Nominations Receipts and Reimbursements Workshop Packets and Web Presence Questions? (Are you feeling flexible?)

4 2005.03.23Marine Metadata Interoperability 3 Overview Background Nature of the challenge Previous work Original proposal Status Community building and outreach Vocabulary work Demonstrations

5 2005.03.23Marine Metadata Interoperability 4 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 2005.03.23Marine Metadata Interoperability 5 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 2005.03.23Marine Metadata Interoperability 6 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

8 2005.03.23Marine Metadata Interoperability 7 Steering Committee Members Robert Arko, LDEO Julie Bosch, NOAA Francisco Chavez, MBARI Ben Domenico, Unidata Karen Stocks, SDSC Steve Hankin, NOAA - Ocean.US/DMAC Roy Lowry, BODC Mark Musen, Stanford Univ Michael Parke, Univ of Hawaii Lola Olsen, NASA Goddard Dawn Wright, Oregon State Univ Bob Weller, WHOI John Graybeal, MBARI. PI. (ExecComm)graybeal@mbari.org Stephanie Watson, GCOOS. (ExecComm) steph_watson@sbcglobal.net Philip Bogden, SURA/SCOOP. (ExecComm)bogden@gomoos.org Stephen Miller, Scripps. (ExecComm)spmiller@ucsd.edu

9 2005.03.23Marine Metadata Interoperability 8 Goals of the MMI Project 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 2005.03.23Marine Metadata Interoperability 9 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

11 2005.03.23Marine Metadata Interoperability 10

12 2005.03.23Marine Metadata Interoperability 11 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 detailshttp://marinemetadata.org/workshop All results will be posted on web site

13 2005.03.23Marine Metadata Interoperability 12 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 2005.03.23Marine Metadata Interoperability 13 VINE tool for mapping between vocabularies http://marinemetadata.org/examples/mmihostedwork/ontologieswork/vine/vine1.0.0.screenshot

15 2005.03.23Marine Metadata Interoperability 14 1) Vocabulary Harmonization 2) Vocabulary Mapping 3) Vocabulary Services 4) Access to Data Demonstration: Status

16 2005.03.23Marine Metadata Interoperability 15 Credits National Science Foundation 1 SURA, the Southeastern Universities Research Association (http://www.sura.org),http://www.sura.org NOAA (including the Coastal Services Center), ONR, the Office of Naval Research (http://www.onr.navy.mil),http://www.onr.navy.mil OceanUS and regional IOOS systems. 1 NSF Grant ATM-0447031

17 2005.03.23Marine Metadata Interoperability 16 Workshop Goals Domain leads (common) Domain leads (unique) MMI project

18 2005.03.23Marine Metadata Interoperability 17 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 2005.03.23Marine Metadata Interoperability 18 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 2005.03.23Marine Metadata Interoperability 19 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
