  1. ISO Standards: Status, Tools, Implementations, and Training Standards/David Danko

  2. What I’m covering • NAP ISO 19115 • Overview of NAP • What’s different and what’s common between FGDC and NAP (and ISO 19115) • ISO Metadata Standards • Fundamental metadata, data quality, feature catalog, imagery and gridded data • What’s new in ISO 19115-1 • Schedule

  3. North American Profile (NAP) of ISO 19115:2003 Metadata • Selection of items from ISO19115:2003 • Promotion of optional fields to mandatory • Extension of code lists • Addition of values to existing code lists • Addition of code lists • Introduction of a multilingual register • Compliant to ISO19135:2005 on registers • English and/et Français • Metadata items • Code lists • Register is accessible on the Web • XML document • Web Services • Web Browser http://www.geoconnections.org/developersCorner/napmetadata/register/index.html

  4. NAP ISO 19115:2003 Title: NAP – Metadata 1. Preface (Introduction) 1.1. About Metadata 1.2. Using Metadata 2. Scope 3. Normative References 4. Terms and Definitions 5. Symbols and Abbreviated Terms 6. Metadata Content 6.1. Best Practices 7. Cultural and Linguistic Adaptability 8. Code Lists 9. NAP Metadata Registry Annexes Data Types Metadata schemas/UML - normative with differences from ISO identified Conformance Clauses Metadata implementation FGDC to NAP Metadata

  5. FGDC NAP FGDC - NAP “Equivalences” Metadata reference info Identification info Data quality Spatial data Organization Spatial Reference info Entity attribute info Distribution info Metadata info Identification Info Constraint info Service info Data Quality info Maintenance info Spatial Representation info Reference system info Content info Portrayal Catalogue info Distribution info Application Schema info

  6. Differences between FGDC – ISO – NAP NAP FGDC ISO Minimum mandatory Unambiguous conditional statements Core metadata International focus Code lists • Moderate increase in mandatory elements • Best practices • Includes service metadata (ISO 19119) • Increased use of code lists • Primarily mandatory elements • Mandatory if Applicable • No language identification requirements • Outdated elements • US oriented reference systems • Heavy use of free text

  7. Comparison of mandatory elements FGDC NAP Metadata info dateStamp Contact Metadata Standard name File Identifier* Language (metadata)* Character set* Parent Identifier (C)* HierarchyLevel (default = dataset)* Locale (C) * (if multiple languages used) Identification information Citation Abstract Status (with codelist) Language* Topic Category* Extent (C) * Bounding box Or Geographic Description* • Metadata Reference info • Date • Contact • Metadata Standard name • Metadata Standard version * • Identification Information • Citation • Description • Abstract • Purpose * • Status • Maintenance frequency * • Progress • Time Period of Content * • Date • Currentness reference * • Spatial Domain • Bounding Box • Keywords * • Theme • Keywords • Access Constraints * • Use Constraints * * Difference FGDC vs NAP

  8. FGDC NAP Comparison of mandatory elements (cont) • Citation • Title • Publication date • Originator • Edition (MifA) • Presentation form (MifA) • Series (MifA) • Publication info (MifA) • Place • Publisher • Other details (MifA) • Larger work citation (MifA) • Citation • Title • Date • Date type • Responsible Party • Individual, organization, and/or position name • Contact information • role

  9. NAP FGDC FGDC Entity–Attribute and NAP Content Info Feature Catalog ISO 19110 Compliant Feature/Attribute Catalog • Coverage Description • Attribute description • Content type code . . . • Entity_and_Attribute_Information = • [1{Detailed_Description}n | • 1{Overview_Description}n | • 1{Detailed_Description}n + • 1{Overview_Description}n] • Detailed_Description = • Entity_Type + • 0{Attribute}n • Entity_Type = • Entity_Type_Label + • Entity_Type_Definition + • Entity_Type_Definition_Source • Attribute = • Attribute_Label + • Attribute_Definition + • Attribute_Definition_Source + • 1{Attribute_Domain_Values}n + • 0{Beginning_Date_of_Attribute_Values + • 0{Ending_Date_of_Attribute_Values}1}n + • (Attribute_Value_Accuracy_Information) + • (Attribute_Measurement_Frequency) • Content Information • Feature Catalogue Description • Compliance code • Language • IncludeWithDataset (M) • FeatureTypes (M) • Feature Catalogue Citation (M)

  10. ISO Metadata standards • ISO 19115:2003 Metadata - revision (ISO 19115-1) (in work) • ISO standards are reviewed every 5 years – vote to revise • Changes not major • Target 2013 • ISO 19115-2:2009 Extensions for imagery and gridded data (complete) • ISO 19139-2 Metadata - XML schema for imagery and gridded data (in work) • DTS released 2011-07-18 vote due 2011-10-18 • ISO 19139:2007 Metadata XML Schema (complete) • Revision pending following 19115-1 completion • ISO 19110:2005 Feature Catalogue Amendment 1 • Just published by ISO - XML Schema FC encoding • ISO 19110 Revision (in work) • First PT meeting • ISO 19157 Data quality (incorporating 19113/19114/19138) (in work) • UML model for Quality • DIS approved

  11. What’s new in ISO 19115-1 • Concept of “recommended core” was removed • Incorporating services metadata from ISO 19119 • Data Quality moving to ISO 19157 • Feature catalog information (entity/attribute metadata) enabled (physically or by link) • Responsible party restructured to enable reuse for different roles • Many new elements added/improved - examples: • metadata identifier improved, MD_Scope and MD_KeywordClass classes added, online linkage in Citation, Reference system type code attribute added, . . ., 74)

  12. ISO 19115-1 FC/EA information OnlineResource reference to the cited resource now included in Citation The feature catalogue

  13. Schedule • ISO 19115-1 • EC revised document sent out for review 2011-8-31 • Vote in Pretoria 2011-11-18 • Draft International Standard 2011-12 • Final Draft International Standard 2012-12 • International Standard 2013-05 • ISO 19157 Data Quality • DIS 2011-06 • FDIS 2012-06 • IS 2013-01 • ISO/TS 19XXX XML schema implementation of ISO 19115-1 • A New Work Item Proposal has been sent to ISO TC 211 to starting work as soon as possible so that we have a schema when ISO 19115-1 final

  14. NAP ISO 19115 and 19110 • NAP ISO 19115 Metadata • Remains stable as is; • Once ISO 19115-1 revision has reached DIS, work will start to create NAP ISO 19115-1 • NAP ISO 19110 Feature Catalog • Work is on hold until work on NAP 19115-1 is started
