1 Preparing for the New Geospatial Metadata Horizon ESRI User Conference San Diego, CA ● July 9, 2003 Lynda Wayne Federal Geographic Data Committee GeoMaxim

2 Why change our standard? Politically… responsible member of international geospatial community Technically… improved normalization enhanced capabilities interoperability

3 What is the status of the ISO metadata standard? ISO design only approved by ISO ISO implementation draft submitted June 2003 ISO 19103, 19109, elements defined externally to ISO 19115/10139 e.g measurements and feature/attribute schemas most in draft form CSDGM remains the US geospatial metadata standard

4 What’s new with ISO metadata? 1. Content CSDGM similar and new elements domains and conditionality core metadata 2. Format UML / XML Multi-level metadata

5 ISO Metadata: New Content CSDGM Similar Elements same metadata standard name new terminology and definitions CSDGM = Originator ISO = Responsible party w/ role = originator custodian owner publisher….

6 ISO Metadata: New Content New (non-CSDGM) Elements International elements Data / Metadata language Extended elements CSDGM = geographic and temporal extent ISO = geographic, temporal, and vertical extent Lacking elements ISO Topic category – 19 standardized subject categories to facilitate data discovery

7 ISO Metadata: New Content Topic Categories – select one or more boundariesoceans transportation economysociety elevationstructure environmentgeoscientific_information healthimagery_basemaps_earthcover inland watersplanning_cadastre locationutilities_telecommunications climatology_meteorology_atmosphere

8 ISO Metadata: New Content Domains and Conditionality Fixed domains and code lists in place of free text Responsible party - role and Topic categories represented as numeric codes role = originator (006) topic category = transportation (018) Fewer mandatory elements Core contains only 7 mandatory elements More optional elements

9 ISO Core Metadata 22 basic metadata elements be that must be maintained for a dataset includes mandatory, conditional, and optional elements all national profiles of ISO must include the core ISO Metadata: New Content

10 Building the national profile ISO Metadata: New Content coreelements extensions

11 mandatory elements: CSDGM Dataset titleTitle Dataset reference datePublication_DateAbstract Metadata point of contactMetadata_Contact Metadata date stampMetadata_Date Dataset language virtual default for US data sets Dataset topic category ISO Metadata: Core Metadata

12 conditional elements: CSDGM Geographic locationBounding_Coordinates - if documenting a data set Dataset character set Metadata character set - if other than UCS Metadata language - if not encoded ISO Metadata: Core Metadata

13 optional elements: CSDGM Dataset responsible partyOriginator Spatial resolution (for raster) Abscissa/Ordinate Resolut. Distribution formatFormat_Name Additional extent-temporalTime_Period_of_Content Spatial representationDirect_Spatial_Reference Reference systemHorizontal_Coord_SystemLineage ISO Metadata: Core Metadata

14 optional elements: CSDGM Online resourceOnline_Linkage & Network_Resource_Name Metadata standard nameMetadata_Standard_Name Metadata standard versionMetadata_Standard_Vers. Metadata file identifier filename for metadata record Spatial resolution (for vector) e.g. equivalent scale 1:24,000 ISO Metadata: Core Metadata

15 ISO Metadata: New Format UML Design: entity relationships

16 ISO Metadata: New Format Data Dictionary: content specifications

XML Schema: metadata record format ISO Metadata: New Format

18 Implications: the good news…. XML schema supports consistent and robust implementation via software tools format and exchange - current implementation via txt, doc, db file, etc - exchange format is txt internal metadata harvesting and other automated features ISO Metadata: New Format

19 ISO Metadata: New Format Multi-level metadata Meta can be created for different levels: Data Series - wetlands Dataset - Paducah wetlands Feature Type - marsh Feature Instance - Mandy’s Marsh Attribute Type - Salinity Attribute Instance - actual % water salinity

20 Implications: the bad news…. Standard can no longer be ‘read’ by most geospatial data developers greater dependency on tools lack of direct contact with the standard will be difficult for some metadata creators, analogous to moving from command line to GUI ISO Metadata: New Format

21 What about my legacy metadata? Crosswalks drafted for: CSDGM Vers. 2.0 Dublin Core, others Conversion software in development sponsored by FGDC ESRI and Intergraph/SMMS development partners

22 How do I prepare? Now…. 1. Continue metadata creation using CSDGM vers.2 !!! 2. Use ISO-poised software ESRI ArcCatalog Intergraph / SMMS 3. Add Topic Categories as a custom element or theme keywords with ‘ISO 19115’ as keyword thesaurus 4. Monitor FGDC website for news, materials, and training opportunities

23 Soon… 5. Participate in FGDC review of crosswalk 6. Participate in INCITS-L reviews 7. Educate and inform your organization that a migration, and assistance, is in the future 8. Develop a metadata conversion plan using crosswalks and conversion software 9. Adopt ‘CSDGM vers. 3.0’ when finalized How do I prepare?

32 What’s new with ISO 19115? New Terminology Replaced terms Data / Metadata Language Extended elements Extent: geographic, temporal, vertical Specified elements Logical Consistency: conceptual, domain, format, topology Hierarchical elements

34 What is ISO? International Organisation for Standards International standards organization - ANSI is US rep to ISO US is one of approximately 92 member nations

35 What is the ISO metadata standard? ISO metadata is one component of ISO TC 211 Geographic Information / Geomatics Joint Steering Group on Spatial Standardization and Related Interoperability

36 ISO/TC 211 Framework and reference model Geospatial models and operators Geospatial data admin Geospatial services Profiles and standards WG 1 ISO/TC Reference model 2. Overview 3. Conceptual schema language 4. Terminology 5. Conformance and testing 7. Spatial subschema 8. Temporal subschema 9. Rules for application schema 20. Spatial operators 10. Cataloguing 11.
