## Executive Order 12906

**NSDI**

_**Executive Order 12906**_

**Coordinating Geographic Data Acquisition and Access: The National Spatial Data Infrastructure” (NSDI)             April 1994**
**(b) Standardized Documentation of Data.    **
** ****..., each agency shall document all new geospatial data it collects or produces, either directly or indirectly, using the standard under development by the FGDC, and make that standardized documentation electronically accessible to the Clearinghouse network**

## FGDC CSDGM

**NSDI**

_**FGDC CSDGM**_

** ****Content Standard for Digital Geospatial**
**   ****Metadata Version 1 (FGDC-STD-001)**
** ****Approved June 8, 1994**
** ****Provided basic framework for metadata activities**
** ****Content Standard for Digital Geospatial**
**    ****Metadata Version 2 (FGDC-STD-001-1998)**
** ****Approved June 19, 1998**

## How Does FGDC Participate in ISO TC211

**NSDI**

_**How Does FGDC Participate in ISO TC211**_

**Via EO12906, FGDC given responsibility for NSDI Standards Development**
**FGDC member of American National Standards Institute L1 Committee**
**ANSI L1 member of ISO TC211**

## FGDC Plans for the ISO Metadata Standard

**NSDI**

_**FGDC Plans for the ISO Metadata Standard**_

** ****Why worry ISO Metadata Standard?**
**Office of Management & Budget Circular A-119**
**    ****- Directs preference in use of International Standards & National Standards**
**Global environment - Global Spatial Data Infrastructure**
** ****FGDC plans to adopt ISO Metadata Standard once approved.**
**Will replace CSDGM Version 2**
**US/FGDC “Profile” development Fall 2000 using ISO Draft International Metadata Standard**

## ISO Metadata & FGDC CSDGM V2

**NSDI**

_**ISO Metadata & FGDC CSDGM V2**_

**ISO/FGDC Metadata Standard Differences**
** ****ISO more elements then FGDC**
** ****Many more “Optional” elements**
** ****Addresses many known deficiencies in FGDC**
**    ****CSDGM (i.e. Raster/Imagery)**
** ****Necessary to meet “international” requirements**
** ****Terminology Differences**
** ****Obligation differences**
** ****Element Name differences**
** ****FGDC Metadata Records are not “yet” ISO compliant**
