Online Documentation Creating and Publishing Metadata in Support of Geospatial One-Stop and the NSDI under 'Best Practices, Data Sharing' see 'Create and Publish Metadata'.

Need for Geospatial Data Standards Standards are imperative to the success of multi- participant projects such as Geospatial One- Stop (GOS). Specifically: Metadata Creation Standards – data discovery Metadata Publication Standards – metadata harvesting, management, and data access

Metadata Creation Standards Currently… US Federal Geographic Data Committee’s (FGDC) Content Standard for Digital Geospatial Metadata, CSDGM Vers. 2.0 Also… ANSI adopted ISO Metadata Standard (UML) Eventually… ANSI CSDGM Vers. 3.0 US Profile of ISO (XML)

Migration to ISO ANSI Implications… increased participation in standard development broader application than federal standard Status stay the course with CSDGM Vers. 2.0 translation tools in development creation tools already available migration to ISO is in progress

GOS Metadata Content Suggestions Quality complete accurate robust Multiple Online_Linkages direct download clearinghouse webmapping applications project websites

Metadata Content Suggestions ISO Topic Categories as Theme_Keywords include one or more ISO Topic Categories as Theme_Keywords ISO Topic Categories farming biota boundaries climateMeteorologyAtmosphere economy elevation environment geoscientificInformation health imageryBaseMapsEarthCover intelligenceMilitary inland Waters location ocean planningCadastre society structure transportation utilitiesCommunications

GOS Metadata Content Suggestions ISO Topic Categories as Theme_Keywords indicate Theme_Keyword_Thesaurus as ‘ISO Topic Categories’ preparation for conversion of CSDGM to ISO (mandatory field) first Topic Category used to make data available from geodata.gov Data Channels

Metadata Publication Standards Format upload and publication in XML format Online_Linkage format OGC Web Map Service (WMS) include ‘getmap’ request w/ layer name, version, and SRS ArcIMS ‘Image’ services using the pseudo URL request direct download sites include URLs that begin ftp:// or and end with.zip,.tgz,.dxf,.e00, etc.

Metadata Publication Standards ISO Theme_Keyword Assignment Option 1: Insert into individual records at collection site: for homogenous collections – scripting to insert same Topic Category into each record for heterogeneous collections – scripting to insert Topic Categories into each record using look-up table

Metadata Publication Standards ISO Theme_Keyword Assignment Option 2: Apply during geodata.gov publisher registration: edit lookup table to reference keywords contained within the collection Topic Categories will NOT be inserted into original records If Topic Categories are not inserted, records will still be searchable via geodata.gov but not via geodata.gov channels
