Supported usage patterns for HTTP URIs

This section illustrates "where", in ISO 19139 metadata records, the XSLT expects to find HTTP URIs (if available), and how they are interpreted.

Metadata URI: Metadata file identifier (ISO 19115)

XPath

//gmd:fileIdentifier/gco:CharacterString

Example

<gmd:fileIdentifier>
  <gco:CharacterString>
    http://some.site/resource/5d3166e1-0685-4a0a-bc0c-02cc7364191a
  </gco:CharacterString>
</gmd:fileIdentifier>

Metadata standard URI: Metadata standard name (ISO 19115)

XPath

//gmd:metadataStandardName/gmx:Anchor/@xlink:href

Example

<gmd:metadataStandardName>
  <gmx:Anchor xlink:href="http://www.iso.org/iso/catalogue_detail.htm?csnumber=26020">
    ISO 19115
  </gmx:Anchor>
</gmd:metadataStandardName>
