The Spatial Data Standards for Facilities, Infrastructure, and Environment (SDSFIE) Metadata standard, or SDSFIE-M is a community standard for geospatial metadata and is a profile of the National System for Geospatial-Intelligence (NSG) Metadata Foundation, or NMF. NMF is, in turn, a profile of ISO 19115:2003/Cor 1:2006 (Geographic Information – Metadata). Version 1.0.2 is currently released in DISR emerging status.
The just approved version of SDSFIE-M (2.0) defines a National System for Geospatial-Intelligence (NSG) Application Schema (NAS) 8.0 Profile (and, specifically, profiles the ISO 19115-1:2014, ISO 19115-1:2014/Amd1:2018, ISO 19115-2:2019, ISO 19157:2013, and ISO 19157:2013/Amd1: 2018, includes elements added by the GeoPlatform Profile of ISO 19115-1, and incorporates elements for the documentation of Controlled Unclassified Information being incroporated into the Intelligence Community Technical Specification XML Data Encoding Specification for Information Security Marking (IC-ISM)). The IGG hopes to acheive a mandated status for SDSFIE-M 2.0 in the DISR 20-1 cycle.
SDSFIE-M is specifically applicable to the Installation Geographic Information & Services Community of Interest (IGI&S COI) as listed in the United States Department of Defense (DoD) Metadata Registry, and having a corresponding IGIS namespace. The SDSFIE supports the ability of the IGI&S COI to describe its spatial data holdings (e.g. those structured according to the Spatial Data Standard for Facilities, Infrastructure, and Environment). Complete and current geospatial metadata is also essential to meet the goals of DoD Instruction 8320.02 summarized as “making data and services more visible (discoverable), accessible, understandable, trusted, and interoperable.”
There are two specifications that describe SDSFIE Metadata:
To develop a clear and comprehensive understanding of what data assets they possess, Federal Agencies are required to create an Enterprise Data Inventory (Inventory) that accounts for all data assets created or collected by the agency. This includes, but is not limited to, data assets used in the agency’s information systems. The Inventory must be enterprise-wide, accounting for data assets across programs and bureaus, and must use the required Project Open Data (POD) metadata schema available on Project Open Data (Project Open Data website).
SMIS is much more comprehensive than the POD metadata schema, therefore the IGI&S Governance Group (IGG) has developed a crosswalk for converting SMIS metadata documents to POD metadata documents. A crosswalk already existed between ISO 19115 (19139) metadata and POD v1.1 (ISO 19115 to PODS Crosswalk). However, there was ambiguity in that crosswalk that had to be resolved before an automatic conversion can be accomplished. The resulting crosswalk is available here:
SDSFIE-M consists of a single document and is availble at the following location:
NEW! The conceptual schema for SDSFIE-M 2.0 was recently approved by the IGG and is availble at the following location:
SMIS consists of a single document and a set of schemas. The schemas have recent bug fixes (APR 2017) and are posted as version 184.108.40.206. All are availble via SDSFIE Online at the following locations:
The schemas for SDSFIE-M 2.0 will be released once it is possible to release the IC ISM specifications on which it depends.
SDSFIE-M is applicable to (and mandated for use by) the Installation Geospatial Information and Services (IGI&S) user community, as defined in DoD Instruction (DoDI) 8130.01. This standard is intended to describe IGI&S spatial data holdings and services (e.g. those structured according to the SDSFIE Vector (SDSFIE-V) standard).
The SDSFIE Implementation Guidance defines the general requirement for IGI&S metadata and expresses, as a series of rules, other implementation requirements for SDSFIE-M such as the need for metadata to be accessible, the requirement to establish milestones and deadlines for the implementation of SDSFIE-M mandated versions, and the need for Components to develop their own implementation plans.
Please be sure to check with your Component IGI&S program for details of the implementation guidance specific to your Component.
Information security is a very important topic with respect to metadata and the SDSFIE-M Implementation Guidance provides rules concerning how information security markings shall be expressed for both metadata and the resources that the metadata describes.
Geospatial metadata is best created and maintained via automated tools. The SDSFIE-M Implementation Guidance includes a rule that any tool that is developed by an IGG member organization must conform to the rules defined in this guidance.
Version 2.0 of the SMIG will be released once it has been finalized and adopted by the IGG.
As stated above, automated tools are essential to the creation and maintenance of metadata. The following is a list of tools that might be useful to those implementing SDSFIE-M:
