  1. Preparing Metadata Records Suresh K.S. Vannan ORNL , Oak Ridge, TN santhanavans@ornl.gov Viv Hutchison US Geological Survey, Denver, CO vhutchison@usgs.gov Data Management Practices for Early Career Scientists 2013 NASA Terrestrial Ecology Science Team Meeting May 2nd , 2013

  2. Understanding the role of metadata

  3. Metadata Topics • Measure • Identify Information to be collected in a metadata record • Explain • Explain metadata collected for data descriptiveness • Test • Test the Quality of information presented • Advertise • Publish the information using metadata standards

  4. Measure - Data Collection

  5. From Field Notes to Datasets Soil Moisture at field sites

  6. Parameter - Description

  7. Parameter – Location and Time

  8. Metadata is a critical part of the data picture

  9. The end is where it begins….. • Providing data to another researcher: • What parameters are contained in the data? • Which temporal and spatial region does this data cover? • What limitations, if any, do the data have? • What does the data describe? • How should the data be cited if it is re-used in a new study? • Receiving data from another researcher: • What are the parameters characterized in this data • What are the data uncertainties? • How was the data measured/? • Are there any fees associated with the data? • In what scale were the data created? • What do the values in the tables mean? • What software do I need in order to read the data? • What projection are the data in? • Is this data set restricted?

  14. Test • City of Salem • 44,-123 • 44.992575,-123.056853

  15. Steps to Create Quality Metadata • Organize your information • Review for accuracy and completeness • Do not use jargon • Use informative title that includes topic, timeliness of the data, and geography • Use “none” , “unknown”, and “nodata” meaningfully • Be specific and quantify when you can • Select keywords wisely – http://gcmd.nasa.gov/learn/keywords.html • Remember: a computer will read your metadata • Fully define entities, attributes, units of measure

  16. Tools for capturing metadata • You - Data creator • Metadata Editors commercial and Open Source • ArcGIS desktop • Oxygen • USGS metadata editor • Metacat • Documentation

  17. Advertise Your Metadata and data: Publish • Share your metadata with other researchers Examples of metadata search portals: • ORNL DAAC • http://daac.ornl.gov • Reverb • http://reverb.echo.nasa.gov/reverb/ • Data.gov • http://data.gov

  18. Let’s Address Concerns…

  19. Final thoughts • Metadata • It isn't easy • It isn't free • Ask everything But… • Protect your research investment and research legacy
