SDSFIE-M — Metadata
Dotted Line

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 the constraints model from NAS for specifying legal and security (Controlled Unclassified Information or CUI) constraints on geospatial metadata and resources in the EI&E business mission area. The IGG has submitted the standard to the GEOINT Standards Working Group (GWG) and SDSFIE-M 2.0 will acheuve mandated status in the DISR 20-2 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.”

Specifications
Dotted Line

There are two specifications that describe SDSFIE Metadata:

  1. SDSFIE Metadata Conceptual Schema (SDSFIE-M)
    SDSFIE-M is a conceptual schema. The purpose of a conceptual schema is to capture the concepts and relationships of a domain model in a form which is agnostic to the eventual choice of an implementing technology. Due to this level of abstraction, compliance with SDSFIE-M cannot be tested directly. Therefore, developers seeking to implement an SDSFIE-M compliant system shall first locate or develop a conformant implementation specification (see SMIS below). SDSFIE-M-conformant implementation specifications provide a validated specification for implementing the SDSFIE-M when employing a specific technology. The implementation specification then serves as a requirements specification that guides system development. Demonstration of compliance of the system with the implementation specification and then conformance of the implementation specification with SDSFIE-M shall constitute demonstration of compliance of the system with SDSFIE-M.
  2. SDSFIE-M Implementation Schemas (SMIS)
    The SDSFIE Metadata Implementation Schemas (SMIS) are the Extensible Markup Language (XML) encoding of the SDSFIE Metadata (SDSFIE-M): Conceptual Schema that is conformant to ISO/TS 19115-3 Geographic information – Metadata – XML schema implementation, for use in the documentation, discovery and exchange of geospatial datasets in the I&E community. This encoding shall be used to document geospatial datasets for cataloguing, discovery and retrieval.

The schemas for SDSFIE-M 2.0 will be released in mid July 2020.

Implementation Guidance
Dotted Line

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.

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:
