Agenda Geospatial Metadata: A Retrospective Drivers for Change Types of Metadata: Discovery/Geospatial The DISDI Metadata Working Group The Proposed I&E Business Mission Area Metadata Standard Way Forward 2
A Metadata Retrospective DISDI Metadata Profile Proposed to DISDIG Mar 07 DISDIG Initiates Metadata Profile 2006 CSDGM 1.0 Established 1994 1997 CSDGM XML Schema Established Chew-n-Spit (CNS) 1999 2000 1998 CSDGM 2.0 Established DTD Established 2001 Metadata Parser (MP) OMB Circular A-16 2002 2003 IVT Metadata Profile 2003 ISO 19115 Published ISO PDTS 19139 Submitted CSDGM FGDC Initiates North American Profile 2005 Stewardship by the FGDC Metadata Coordinator Denver, CO DoD Service Components Utilize to describe & manage installation geospatial assets 2005 1994 1998 2003 Milestone FGDC ISO 2006 DISDI 3
Net-Centric Enterprise Strategy (NCES) DISDI Metadata Profile Drivers Why? Defense Information Technology Standards Registry (DISR) Defense Discovery Metadata Specification (DDMS) National System for Geospatial-Intelligence (NSG) Geospatial- Intelligence Working Group (GWG) GWG Metadata Focus Group (MFG) & the Common Core Installation Visualization Tool (IVT) DISDI Spiral II Architecture FGDC DRAFT North American Profile (NAP) 4
Types of Metadata Data Asset & Geospatial Data Asset Metadata Defense Discovery Metadata Specification (DDMS) Facilitates macro-level data asset enterprise discovery Net-centric business AND geospatial data model for all DoD business related data assets on the Global Information Grid (GIG) Geospatial Metadata - ISO 19115 Geographic Information Metadata Objective: Focus on describing micro level geospatial data Supports enterprise digital geospatial enterprise discovery & data management The DoD Information Technology Standards Registry (DISR) recognized geospatial metadata standard 5
Standards Profiling What is a standards profile? A customized version of an abstract standard(s) Standard Broad/complex Generic Optional Undefined domains Profile Narrow Specific Specific Mandatory Explicit Domains ISO 19111 19108 19115 Data Time CRS Elements A Standard Tailored for Our Community 6
The DISDI Metadata Working Group Appointed by the DISDI Group Technical working group to the DISDI Community of Interest (CoI) Establish a common, cross- Service I&E metadata profile to align with DoD Net-centric data strategies DISDI Metadata Working Group Oct 06 Reduce impact to current mission 7
The DISDI Metadata Working Group Issues Considered What are the drivers/requirements? Level of effort? Where to start? (vector/imagery) What to include? ( nice to have vs requirements) Feature/Hierarchy levels? Work Group Challenges Comprehension of ISO 19115 complexity detailed vs limited data element requirements Ensuring current required data elements identified & incorporated Alignment with existing & emerging standards FGDC North American Profile (NAP) NSG Metadata Common Core Defense Discovery Metadata Specification Initial Issues & Challenges 8
The DRAFT Profile Baseline Framework Required Elements Section 6 Data Dictionary Appendix A Code Lists Appendix B Profiling Rules Appendix C Example Appendix F Test Suite 1 Remaining Work RP&ILM Approval Tools The Profile is a true Living Document 9
Enhanced Content Standard for Digital Geospatial Metadata 10
DISDI Geospatial Metadata Profile 1.0 Statistics 70+ Mandatory Attributes 7 Conditional Attributes 100 s Optional Attributes 5 MD_Metadata (i.e. Data Quality) 5 MD_Extent (i.e. Temporal Extent) What has changed? Modified Entity/Attribute Information Reference System Info Additional features Language Character Set Encoding Codelists 11
The XML Schema TargetNamespace: disdi 12
Supports testing for XML Conformance/Validation Based on DISDI UML Models Utilizes ISO 19139 Captures DISDI Specific Requirements/Changes Optional to Mandatory Any future changes to the Codelists ( drop-downs ) The XML Schema Required Formalized DISDI Namespace for Completion http://metadata.dod.mil/mdr/ns/disdi Upon approval of specification, XML Schema can be entered into the DoD Metadata Registry 13
Value / Benefits Alignment with the DoD Metadata Registry Defense Discovery Metadata Specification Common Vocabulary Community consensus on definitions Flexibility All communities have opportunity to refine the standard to their required business mission area processes Postured for FGDC alignment without major impact Will most likely require some minor adjustments 14
Way Forward RP & ILM DGB Approval Tool Development Translation & Publishing / Editing Capabilities Version 2.0 Considerations Closer alignment with NSG metadata Core i.e. Quality metadata Quality Assurance Plans More structured metadata governance process i.e. Configuration Support Panel(?) Refine mappings to DDMS Current Security Constraints codelist will need attention Refine Metadata Test Suite DMWG may want to build a more robust test environment 15
