  1. Quality Metadata Presented by Sharon Shin, FGDC Developed by Lynda Wayne, GeoMaxim-FGDC

  2. Quality Metadata is… • Complete • Accurate • Comprehensible • Discoverable + A

  3. Complete Metadata Metadata must be complete in both: • Extent sufficient elements to describe the data • Content robust information provided within those elements Quality metadata has both breadth and depth

  4. Complete Metadata: Extent Start with… all mandatory metadata elements Select… additional metadata elements pertinent to your data,data type Requires familiarity with the scope of the standard but knowledge of only a core set of elements

  5. What is Mandatory? Metadata Information • http://biology.usgs.gov/fgdc.metadata/version2 • http://www.nbii.gov/datainfo/metadata/standards/bdp.html Identification Information Spatial Reference Information Distribution Information Data Quality Information Entity and Attribute Information Spatial Object Information

  6. What is Mandatory…pertinent to data, data type,

  7. Complete Metadata: Extent Templates make metadata faster/easier: • Select elements applicable for broad use • Determine content for fixed elements, e.g.: • Contact Information • Liability and Constraint Statements • Distribution Methods Consider templates for the organization, specific data types, and individual projects

  8. Make Metadata Easier

  9. Complete Metadata: Extent Utilize extensions and profiles: • Existing (FGDC) • Biological Profile • Shoreline Profile • Remote Sensing Extension • Community specific- • Present to FGDC for recognition, acknowledgement Profiles (vs. extensions) include specific guidance on content for non-extended fields

  10. Complete Metadata: Content Provide Robust Information, especially for: • Titles- unique identification what, where, when, who, why, and how) • Abstracts data set format and content (attributes) • Purpose • Program name • Supplemental_Information • record special information • ‘front’ information See handout ‘Metadata Cliff Notes’ posted at http://www.fgdc.gov/metadata/education.html

  11. Complete Metadata: Content • Theme_Keyword use ISO Topic Categories in addition to project keywords • Use_Constraints note data set is not a survey data product note intended use of the data and its limitations • Accuracy include quantitative measures when able • Process_Step record during data development

  12. Complete Metadata: Content • Abscissa/Ordinate Resolution • vector = fuzzy tolerance • raster = cell size • Entity and Attribute Description • Overview if documented elsewhere • Detailed as opportunity to document Time spent providing robust information is time saved fielding inquiries

  13. Accurate Metadata Correct Information: • Include all data contributors (sans sources) • If you don’t know – say so Current Information • Create metadata during data development • Review and update regularly ArcCatalog support accuracy via synchronicity

  14. Comprehensible Metadata DLG Use Good Writing Skills • spelling • grammar • capitalization • spell out acronyms Write plainly for Abstracts and Titles and save the technical jargon for the Processing Information LIDAR GIS FIPS

  15. Discoverable Metadata Use a Metadata Standard • CSDGM geospatial digital data • Dublin Core (DC) web documents • Government Info Locator System (GILS) government documents Most data ARE geospatial !

  16. Discoverable Metadata Use recognized resources • CHECK FOR USGS THESAURI URL • Professional e.g., Cowardin Wetland Classification • GOS / ISO Topic Categories – Data Categories Use both broad and narrow keywords

  17. Additional Metadata Resources FGDC Metadata Website http://fgdc.gov/metadata/ education.html tutorials, trainers, training calendar MetadataCliff Notes and other resources community.html metadata listserver, what’s new, working group metalinks.html tools, thesauri, and other online resources
