Why bother with metadata standards?
• Content checklist for authors
• Common understanding of geospatial data
- Between countries
- Between communities
• Publish to metadata catalogs
• Consistent terminology for global search

A Metadata Standard for IGI&S:
Spatial Data Standards for Facilities, Infrastructure, and
Environment - Metadata (SDSFIE-M)

Acquisition, Technology and Logistics
Agenda
• Overview and history of SDSFIE Metadata
• Description of SDSFIE-M
• Description of SDSFIE-M Implementation Schema
• Status and Description of SMIS Metadata Style for ArcGIS 10.1
• Next Steps
12
Acquisition, Technology and Logistics
• Geospatial Metadata is required for all SDSFIE data, per OMB
Circular A-16 and DoD Directive 5105.6 (GEOINT Functional
Management)
• Current SDSFIE metadata is compliant with old standard
developed by Federal Geographic Data Committee (FGDC)
• New ISO-based standards were finalized by NGA and FGDC in
2012
• DISDI Group developed a profile of ISO 19115 known as
SDSFIE Metadata(SDSFIE-M) v1.0.2
• Compliant with NGA and FGDC requirements as well as DoD
Discovery Metadata Specification (DDMS)
• SDSFIE-M v1.0.2 (specification) is now complete and DISDI
Group is drafting implementation guidance
SDSFIE Metadata (SDSFIE-M) 1.0.2
Acquisition, Technology and Logistics

What is SDSFIE-M? (Cont.)
• A conceptual schema…
• A Class 2 Profile of ISO/TC 19115:2003/Cor 1:2006 and ISO/TC 19115-2:2009 intended for use by the Installation Geospatial Information and Services (IGI&S) community
– MD_Distribution is not included in our profile
• All extension elements from National System for Geospatial Intelligence Metadata Foundation (NMF) Parts 1, 2 and 3 (version 2.1) are included except NMF_DataIdentification
• All extensions from North American Profile of ISO/TC 19115:2003 are included
• SV_ServiceIdentification from ISO/DIS 19115-1 is included
• Added an SMF_Feature data type to allow for alias name, model name, justification, definition, description, and note from SDSFIE.

SDSFIE Metadata Implementation
Specification (SMIS)
• SMIS is the implementation specification for SDSFIE-M
– The structure is expressed in XML Schema
– Schematron rules implement the content validation that (e.g., restriction of elements to
codelist values, enforce mandatory elements, implement relationships between elements,
valid day, date, time elements)
– Many tools can handle the XML Schema structural validation
– Tools like <oxygen/> XML Editor can handle content validation
• SMIS includes a document, XML schemas, Schematron files, code lists
Acquisition, Technology and Logistics
SDSFIE Metadata Implementation
Specification (SMIS)
• SMIS Document
– Based on NSG Metadata Implementation Specification, Part II: XML Exchange Schema
– Technical description of how the SMIS schemas were created as a profile of ISO 19139
and 19139-2 schemas with extensions from National System for Geospatial-Intelligence
(NSG) Metadata Implementation Specification (NMIS), North American Profile of ISO
19115:2003/Cor. 1:2006 (NAP), XML Data Encoding Specification for Information
Security Marking Metadata (DES.ISM), and XML Data Encoding Specification for Need-
To-Know Metadata (DES.NTK)
• DISDI Group adopted 1.0.2 version in September
Acquisition, Technology and Logistics
SMIS 1.0.2 Schemas Posted to DSE
• Schemas that correspond to SDSFIE-M 1.0.2 are posted to the DSE
– http://metadata.ces.mil/dse/ns/DISDI/smis/1.0.2/smis.xsd
• Lacking Schematron updates until Beta stage of SDSFIE-M Metadata Style is complete (under development)
– Need to ensure DSE codelists and Metadata Style codelists align
Acquisition, Technology and Logistics
18
SDSFIE-M Metadata Style for ArcGIS
• January, 2014 DISDI Program developed an
ArcGIS metadata style
– Alpha testing has completed
– DISDI Group members conducted limited user tests
– Several comments received
• The beta version of the SDSFIE-M Metadata Style
(ArcGIS 10.1) will be on DSE by the end of the week
and can be downloaded and tested
– http://metadata.ces.nil/dse/ns/DISDI/sdsfiemetadatastyle
• ArcGIS 10.2 version coming in early March
