3 How do ISO metadata standards compare to FGDC metadata standards?
Student shall be able to list the differences and similarities between FGDC CSDGM and ISO What is ISO Metadata? How do ISO metadata standards compare to FGDC metadata standards?

4 Today’s Topics Why ISO Metadata What is ISO Metadata
General Overview of ISO Content and Organization

5 Each country may have their own policy/standard or profile of a standard set. We will focus on the United States and the ISO recommended standards. Why ISO Metadata?

6 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 Executive Order Signed by Pres. Bill Clinton Apr. 11, 1994 This Executive Order established the National Spatial Data Infrastructure to support public and private sector applications of geospatial data in such areas as transportation, community development, agriculture, emergency response, environmental management, and information technology. This Executive Order also 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. Several objectives were defined to promote the population of the NSDI with geospatial data held by Federal agencies and other organizations. These included: inventory of spatial data holdings development of a plan to document new spatial data sets documentation of all data sets created after January 11, 1995 placement of descriptive information (metadata) in an online searchable service starting in January 1995 online access to spatial data sets through the metadata, where feasible.

7 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 OMB Circular A-16, revised August 19, 2002, is a Government circular that was created by the United States Office of Management and Budget (OMB) to provide 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). The circular 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. The Secretary of the Interior is established as chair, with the Deputy Director for Management, OMB as Vice-Chair. Any agency that collects, produces, acquires, maintains, distributes, uses, or preserves any form of spatial data either directly or indirectly with any other agency or organization must follow the policies set forth by the circular. The FGDC is an interagency committee delegated to manage OMB Circular A-16 related activities and implementation of NSDI policy and procedures in accordance with existing federal law and policy.

ISO 19110:2005 Geographic information - Methodology for Feature Cataloguing ISO 19111:2007 Geographic information - Spatial referencing by coordinates ISO 19115:2003 Geographic information – Metadata ISO :2009 Geographic information – Metadata - Part 2: Extensions for imagery and gridded data ISO 19119:2005 Geographic information – Services ISO 19139:2007 Geographic information – Metadata – XML schema implementation INCITS Information technology – North American Profile of ISO 19115:2004 – Geographic information – Metadata (NAP – Metadata) Talk a bit about ISO and the use of XML

10 Student should be able to describe how to validate ISO metadata
What is ISO Metadata?

11 ISO Geospatial Metadata
ISO – International Organization for Standardization Use the 191** series ISO 19115:2003/Cor 1:2006 Geographic information - Metadata ISO :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 What is ISO? ISO (International Organization for Standardization) is the world’s largest developer of voluntary International Standards. Founded in 1947. ISO is a network of national standards bodies. These national standards bodies make up the ISO membership and they represent ISO in their country. Because 'International Organization for Standardization' would have different acronyms in different languages (IOS in English, OIN in French for Organisation internationale de normalisation), our founders decided to give it the short form ISO. ISO is derived from the Greek isos, meaning equal. Whatever the country, whatever the language, the short form of our name is always ISO.

12 Comparing FGDC and ISO 19139 XML schema implementation RSE CSDGM BIO
Part 2: gridded data and imagery 19115 Geographic information - Metadata North American Profile of (NAP) 19110 MI_ MD_ FC_ 19119 Services SV_ 19157 RSE BIO CSDGM Core Info DQ E&A Spatial Ref Info Comparing FGDC metadata standards, such as the CSDGM, RSE, and BIO, to ISO metadata standards such as 19115, , 19110, 19139, and NAP The CSDGM is the core, or base, of the FGDC standards for documenting geospatial data. Profiles and extensions to the core standard can shorten or extend the main standard and can change conditionality. The Biological Profile (BIO) extends the CSDGM in order to properly document biological information. The Remote Sensing Extensions (RSE) extends the CSDGM in order to document information about imagery and other remotely sensed data. The core ISO standard for documenting geospatial data is the ISO Geographic information – Metadata. ISO Geographic information – Metadata – Part 2: Extensions for imagery and gridded data extend the ISO in order to properly document information about imagery, gridded data, and remotely sensed data. The North American Profile (NAP) is a profile of the ISO The NAP shortened the core and changed conditionality and multiplicity on several elements. The ISO Geographic information – Methodology for feature cataloguing is a separate standard and separate document that the ISO will reference if it exists. The ISO is much like Section 5, Entity and Attribute Information, of the CSDGM. The ISO Geographic information – Spatial referencing by coordinates is also a separate standard and separate document that may be referenced from the ISO The ISO defines the XML encoding of the ISO metadata standards. The ISO provides the structure and rules to which the validation should be set. MD root = 19115 MI root = ISO → FGDC CSDGM (FGDC-STD ) ISO → FGDC Remote Sensing Extensions (RSE) (FGDC-STD ) ISO → FGDC CSDGM Section 5 (Entity & Attribute Info) ISO → FGDC CSDGM Section 2 (Data Quality Info)

13 ISO Background We are still capturing the same information!
The content of ISO strongly resembles the ‘sections’ of the CSDGM. ISO provides information about the geographic data OR service : Identification info Spatial Reference info Data Quality info Distribution info Metadata info We are still capturing the same information! Adding service metadata

14 Comparison of FGDC and ISO Main Sections of FGDC CSDGM
Identification Information Data Quality Information Spatial Data Organization Information Spatial Reference Information Entity and Attribute Information Distribution Information Metadata Reference Information Main Sections of ISO 19115 Metadata Information Spatial Representation Information Reference System Information Metadata Extension Information Identification Information Content Information Distribution Information Data Quality Information Portrayal Catalogue Information Metadata Constraints Application Schema Information Metadata Maintenance Information

15 New with ISO Is far more 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 These are just a few of the added benefits to transitioning to NAP/ISO. ISO introduces a structured hierarchy for the documentation of related ‘levels’ of data including: dataset series datasets features data attributes New Technologies Many new geospatial data technologies have emerged since the 1998 publication of the CSDGM Vers. 2.0 including, but not limited to: web-mapping data models online data catalogs, warehouses and sales online data processing ontologies, thesauri, data hierarchies and classification systems International Scope To accommodate the writing of metadata for multiple nations and international organizations, the ISO includes attributes to record: Dataset Language Dataset Character Set Metadata Language Metadata Character Set Preparing for International Metadata details what new with ISO/NAP

16 ISO 19115 Geographic information – Metadata
Student should be able to identify where certain information belongs within the ISO metadata standard. ISO Geographic information – Metadata ISO 19115:2003(E)

17 Metadata written using ISO still answers these important questions:
ISO Content Metadata written using ISO still answers these important questions: Who collected the data? processed the data? wrote the metadata? to contact for questions? to contact to order? owns the data? 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? ISO lets you answer these questions in more detail 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?

18 Organization and Content of ISO
Organized in Sections and Packages Section: Groupings of similar information similar to CSDGM Sections Package: Logical groupings of elements found in multiple locations within Sections similar to CSDGM “supporting sections”

19 Main Sections of ISO 19115 Metadata
Metadata Information (MD_Metadata) Root element that contains information about the metadata itself. Root contains main sections. Spatial Representation Information (gmd:spatialRepresentationInfo) geospatial representation of a resource Reference System Information (gmd:referenceSystemInfo) spatial and temporal reference systems used in the resource Metadata Extension Information (gmd:metadataExtensionInfo) user specified extensions to the metadata standard used to describe the resource Identification Information (gmd:identificationInfo) uniquely identify a resource or resources Content Information (gmd:contentInfo) physical parameters and other attributes contained in a resource Distribution Information (gmd:distributionInfo) who makes a resource available and how to get it Data Quality Information (gmd:dataQualityInfo) quality and lineage (including processing steps and sources) of a resource Portrayal Catalogue Information (gmd:portrayalCatalogueInfo) collection of defined symbols used to depict, to humans, features on a map Metadata Constraint Information (gmd:metadataConstraints) constraints on the use of the metadata and the resource it describes Application Schema Information (gmd:applicationSchemaInfo) application schema used to build a dataset Metadata Maintenance Information (gmd:metadataMaintenance) maintenance of the metadata and the resource it describes The root MD_Metadata, contains these other main sections. MD_Metadata contains information about the metadata itself (no metadata reference info section as in CSDGM) as well as these other main sections.

20 Main Sections of ISO 19115-2 Metadata
Metadata Information (MI_Metadata) Root element that contains information about the metadata itself. Root contains main sections. Spatial Representation Information (gmd:spatailRepresentationInfo) geospatial representation of a resource Reference System Information (gmd:referenceSystemInfo) spatial and temporal reference systems used in the resource Metadata Extension Information (gmd:metadataExtensionInfo) user specified extensions to the metadata standard used to describe the resource Identification Information (gmd:identificationInfo) uniquely identify a resource or resources Content Information (gmd:contentInfo) physical parameters and other attributes contained in a resource Distribution Information (gmd:distributionInfo) who makes a resource available and how to get it Data Quality Information (gmd:dataQualityInfo) quality and lineage (including processing steps and sources) of a resource Portrayal Catalogue Information (gmd:portrayalCatalogueInfo) portrayal catalogues used for the resource Metadata Constraint Information (gmd:metadataConstraints) constraints on the use of the metadata and the resource it describes Application Schema Information (gmd:applicationSchemaInfo) application schema used to build a dataset Metadata Maintenance Information (gmd:metadataMaintenance) maintenance of the metadata and the resource it describes Acquisition Information (gmi:acquisitionInformation) instruments, platforms, operations and other info of data acquisition (only MI_Metadata) ISO extends ISO specifically for imagery and gridded data. The root of ISO metadata records will change from MD_Metadata to MI_Metadata when using ISO A new section is also added, gmi:acquisitionInformation includes the new package, MI_AcquisitionInformation.

CI Citation DQ Data Quality DS Dataset EX Extent FC Feature Catalogue GM Geometry LE Lineage Extended (added in ISO ) LI Lineage MD Metadata MI Metadata for Imagery (added in ISO and replace the root MD) RS Reference System QE Data Quality Extended You may also notice some XML has a two letter code followed by an underscore. Ex: CI_ResponisbleParty ISO is organized into groups called packages. These are like the “supporting sections” found within the main sections.

25 Guide to Implementing ISO Metadata
Student should be able to identify where certain information belongs within the ISO metadata standard and the valid format of that entry. Guide to Implementing ISO Metadata

26 Workbook for ISO 19115 parallels the standard provides FAQs
implementation guide Workbook includes best practices for NAP compliance

27 Using the Workbook Is a resource for applying the ISO metadata standard Uses a Graphical Representation of the production rules Describes domain values valid values that can be assigned to the data element Provides names and definitions

28 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. The workbook is a resource for applying the ISO metadata standard and its profiles. It provides names and definitions, describes domain values (valid values that can be assigned to the data element), and uses a graphic representation of the production rules. The workbook is organized by main sections and supporting packages. The main sections are documented in the order in which they appear in the standard. The packages are refered to from various points within the main sections and other packages. The packages are documented in alphabetical order. The workbook includes the selected geographic information metadata standard implementation guide as well as the feature catalogue standard implementation guide. The workbook also documents differences between the ISO standard and the NAP. NAP compliancy is documented at “Multiplicity”. The workbook is structured as follows; the fileIdentifier is an example of that structure.

29 Using the Graphics The graphics were generated automatically from the actual ISO schemas using Altova’s XMLSpy software. The graphics were then cleaned-up to provide easier to read graphical representations of the standard. The legend of symbols required to read the graphics is provided below. Additional symbols are the result of the automating software and are not considered necessary to the understanding of the standard. Each name in each box is an XML tag

30 ISO is arranged a little funny (due to the schemas) but MD_Metadata is the root that contains all of the information. fileID, language, characterSet, parentID, hierarchyLevelName, contact, dateStamp, metadataStandardName, metadataStandardVersion, datasetURI, and locale are all elements describing the metadata information (metadata reference info in FGDC CSDGM). The other main “sections” aka classes of ISO are spatialRepresentationInfo referenceSystemInfo metadataExtensionInfo IdentificationInfo contentInfo distributionInfo dataQualityInfo portrayalCatalogueInfo metadataConstraintInfo (in FGDC CSDGM this is included in the metadata reference info) applicationInfo metadataMaintenanceInfo (in FGDC CSDGM this is included in the metadata reference info)
