It is recommended to use the gmx:Anchor element, when the provided text is a term or code. However, the use of the element gco:CharacterString is allowed for backward compatibility with an existing Resource Locator description that might be already compliant with this simplification approach.
Implementation Guidelines
The <gmd:protocol> element should be encoded as gmx:Anchor. The attribute xlink:href should point to a valid unique resource identifier of the INSPIRE Protocol values codelist. The text value should match the related codelist label, expressed in the metadata language where available.
Encoding example: View Service locator with <gmx:Anchor>:
| <gmd:protocol>
<gmx:Anchor xlink:href="http://www.opengis.net/def/serviceType/ogc/wms">OGC Web Map Service</gmx:Anchor>
|
Encoding example: View Service locator with <gco:CharacterString>:
| <gmd:protocol>
<gco:CharacterString>OGC Web Map Service</gco:CharacterString>
</gmd:protocol> |
