Using standardized locations of metadata encourages common understanding of the content and improves search-ability of the content. NOAA Supplemental elements are unsupported and there is no current documentation or practices to support their usage. The NOAA Supplemental content can be migrated to elements supported by the FGDC with Remote Sensing Extensions standard (2002), base FGDC elements (1998) and ISO extensions included in the NMMR.

Suggested Crosswalk between NOAA Supplemental Elements and Standard Elements

This crosswalk is based on an interpretation of the NOAA Supplemental Elements and their usage in NGDC. Metadata editors should review their content and the standards to decide the best location within the metadata.

Related Mandatory Elements

When the content in NOAA Supplemental elements are moved to a standard element, the standard often requires the metadata eidtor to populate related elements for creating a valid FGDC metadata record. I attempted to capture the other elements that will be required, however, it is difficult to represent and may be subject to errors. I suggest that you research the standard so you can meet your metadata needs best.

Editing NOAA Supplemental

How to Edit

Editors can write an XUpdate script to move the content or copy/paste content to appropriate elements. XUpdate is a language based on XSLT to automatically edit the content of one or many xml records at once. There is an interface in the NMMR for running this on selected metadata records. It is a useful tool when it works, but there are limitations to it's usage in the NMMR. For instance, it will not update metadata that is part of a component record, such as a citation. XUpdate can be used to move content from NOAA Supplemental to other elements. For more information about XUpdate go to wiki page XUpdate.

The table below shows what NOAA Supplemental elements could potentially be moved with XUpdate and what elements cannot, based on the crosswalk above.
