Not able to validate metadata using ISO 19139 Metadata Implementation Specification

Error Message

When trying to validate metadata using the ISO 19139 Metadata Implementation Specification metadata style, the user receives the following error:

 "The remote server returned an error: (404) Not Found. Failed to execute (Validate Exported Metadata)."

Cause

The Schema Url: "https://www.isotc211.org/schemas/2005/gmd/metadataEntity.xsd" does not exist.

Solution or Workaround

When running the Validate Metadata tool, change the parameter Schema Url from:

https://www.isotc211.org/schemas/2005/gmd/metadataEntity.xsd

to:

https://www.isotc211.org/2005/gmd/metadataEntity.xsd

To change the default parameter of this tool, so that it is not necessary to change it manually each time one wants to validate a metadata, modify the CFG file of the metadata style. This is located in the following path:

C:\Program Files (x86)\ArcGIS\<ArcGIS Version>\Metadata\Config\ISO 19139 Metadata Implementation Specification

To modify this file, run Notepad as an administrator and open it. Change the line:

<validationSchemaURL>https://www.isotc211.org/schemas/2005/gmd/metadataEntity.xsd</validationSchemaURL>

to:

<validationSchemaURL>https://www.isotc211.org/2005/gmd/metadataEntity.xsd</validationSchemaURL>

This sets the default parameter with the correct URL.
