  3. Why ISO Metadata • What is ISO Metadata • General Overview of ISO Content and Organization

  4. Why ISO Metadata?

  5. Executive Order 12906 • Established the National Spatial Data Infrastructure (NSDI) to support public and private sector applications of geospatial data  • Established an electronic National Geospatial Data Clearinghouse for the NSDI to address data standardization, make geospatial data publicly available, and address redundancy and incompatibility of geospatial information

  6. OMB Circular A-16 • Provides guidance for federal agencies that create, maintain or use spatial data directly or indirectly through the establishment of the National Spatial Data Infrastructure (NSDI) and the Federal Geographic Data Committee (FGDC) • Establishes guidelines for the management of digital spatial data and the use of those assets. It also appoints the FGDC to the interagency coordinating body for NSDI-related activities

  7. FGDC Endorsed Standards

  8. What is ISO Metadata?

  9. ISO Geospatial Metadata • ISO – International Organization for Standardization • Use the 191** series • ISO 19115:2003/Cor 1:2006 Geographic information -- Metadata • ISO 19115-2:2009 Geographic information -- Metadata -- Part 2: Extensions for imagery and gridded data • ISO/TS 19139:2007 Geographic information -- Metadata -- XML schema implementation   • ISO 19110:2005/Amd 1:2011 Geographic information -- Methodology for feature cataloguing • ISO 19119:2005/Amd 1:2008 Geographic information -- Services Extensions of the service metadata model

  10. Understanding ISO Standards 19139 XML schema implementation 19111 19110 FC_ MI_ MD_ 19119 Services 19157 SV_ DQ_ ISO 19115 → Core Information ISO 19115-2 → Extensions for Instrumentation and Gridded Data ISO 19110 → Entities and Attributes ISO 19119 → Services ISO 19157 → Data Quality

  11. Is flexible Depicts relationships between datasets and collection level (parent/child relationships) Standardizes descriptors through the use of codelists Accommodates new technologies (such as documenting services) Accommodates International scope Undergoes revision/review in 5 year cycles ISO Metadata

  12. ISO 19115:2003(E)

  13. ISO Content Metadata written using ISO still answers these important questions: Where were the data collected? were the data processed? are the data located? When were the data collected? were the data processed? What are the data about? project were they collected under? are the constraints on their use? is the quality? are appropriate uses? parameters were measured? format are the data in? How were the data collected? were the data processed? do I access the data? do I order the data? much do the data cost? was the quality assessed? Why were the data collected? Who collected the data? processed the data? wrote the metadata? to contact for questions? to contact to order? owns the data?

  14. Organization and Content of ISO • ISO is organized in Sections and Packages • Section: Groupings of similar information • Package: Logical groupings of elements found in multiple locations within Sections

  15. Guide to Implementing ISO Metadata http://www.ncddc.noaa.gov/ metadata-standards/

  16. Workbook of ISO 19115 • parallels the standard • provides FAQs • implementation guide

  17. Using the Workbook • is a resource for applying the ISO • metadata standard • provides names and definitions • describes domain values (valid values that can be assigned to the data element) • uses a Graphical Representation of the Production Rules

  18. Using the Workbook Tag: XML tag Definition: definition of the tag Type: type or package Domain: format of the content Multiplicity: if something is repeatable and if it is required Attributes: XML attributes Best Practices: recommended implementation fileIdentifier – A unique phrase or string that uniquely identifies the metadata file. Type: gco:characterString Domain: free text Multiplicity: optional *this is NAP requirement* Attributes: nilReason Best Practices: Each metadata record shall have a universal unique identifier (UUID) to distinguish it from others.
