  1. Sharon Shin • Physical Scientist • Former life- Cartographer, Environmental Protection Specialist, Statistical Technician • Education- • University of Colorado, Denver • Metropolitan State College.

  2. Key organizations • FGDC - Federal Geographic Data Committee • NSDI - National Spatial Data Infrastructure

  3. Front Range Community College April 16, 2009

  4. Product? Weight? Expiration date? Serving size? Nutrition? Fat Sodium Fiber Metadata? Metadata

  5. Metadata- Message • Metadata marketing in the past… • If you create metadata, other people can discover your data • New and improved message… • If you create metadata,you can find your own data

  6. data discovery Data Distribution via Metadata metadata publication dataportals

  7. keywords • geographic location • time period • attributes • online access • order process • contacts • use constraints • access constraints • data quality • availability/pricing IDENTIFY ACCESS ASSESS Distribution: Data Discovery • The descriptive content of the metadata file can be used to identify, assess and access available data resources.

  8. Distribution- Discovery • Find you data by: • themes / attributes • geographic location • temporal character • analytical methods used • sources and contributors • data quality Discoverable data is usable data Monument to the Discoverers, Lisbon, Portugal

  9. Internet / Intranet Data Set Distribution: Metadata Publication • A metadata collection can be published to the Internet via: • web accessible folder (waf) * • website catalog • Z39.50 metadata clearinghouse • metadata service • geospatial data portal Internet User Query Metadata Collection

  10. Distribution: Geospatial Data Portals • State Portals: • Colorado Geographic Information Portal http://coloradogis.nsm.du.edu/Portal/ • Others

  11. Distribution: Geospatial Data Portals • Federal and National Portals: • Geospatial One-Stop (GOS) Federal e-gov geospatial data portal www.geodata.gov • Geography Network ESRI sponsored national geospatial data portal www.geographynetwork.com

  12. Distribution: Thematic Portals: • National Biological Information Infrastructure USGS portal to national biological data http://www.nbii.gov/portal/server.pt • National Park Service Data Store NPS’s gateway to geospatial data searchable park unit or category, text- keyword, title, abstract. http://science.nature.nps.gov/nrdata/ • Geospatial Data Gateway: Natural Resource Data USDA portal to national natural resource data http://datagateway.nrcs.usda.gov/

  13. DataAccountability Discovery & Re-use Data Management via Metadata Maintenance & Update DataLiability

  14. Management: Maintenance and Update • Data Maintenance • Data Update

  15. Management: Data Accountability • Metadata is an exercise in data accountability. It requires you to assess: • What do you know about the data set? • What don’t you know about the data set? • What should you know about the data set? Methods used are a repeatable process and defendable. Are you willing to associate yourself with the metadata record ?

  16. What to do… What not to do… Management: Data Liability • Metadata is a declaration of: • Purpose • Use Constraints • Completeness • Distribution Liability

  17. Management: Data Accountability • Return on Investment • Catalog assessment: • # time data occurs, in-house, as source • # times data occurs, external, as source • significance of source contribution methods • To facilitate assessment • use standardized tilting schemes • indicate preferred data set citation w/in Use Constraint Statement

  18. Project Coordination Project Management via Metadata Project Planning Project Monitoring Contract Deliverables

  19. Project Management: Project Planning • Project design document • descriptions & intent • geographic and temporal extent • source data • attributes requirements • Benefits: • expectation are clearly outlined • metadata is integrated into the process • provide medium to record progress

  20. milestones time Project Management: Project Monitoring • Monitor • data development status • QA/QC assessments • needed changes Requires that the metadata be actively maintained and reviewed

  21. template Project Management: Project Coordination • Common reference for: • descriptions & parameters • keywords, vocabularies, thesauri • contact information • attributes • distribution information • If reviewed regularly by all participants, improved opportunity for coordinating: • source data • analytical methods • new information

  22. Project Management: Contract Deliverables • As a key component of the data, metadata should be part of any data deliverable • For best quality metadata, provide: • classification and/or validation schema • metadata content template • metadata specification manual Provide a sample metadata record if possible

  23. Conclusions • Metadata is simply information about data • Information that you needto effectively: • locate • manage • utilize internal and external data resources. Creation of robust metadata is in your OWN best interest!
