#A.14.IR16.IR17.IR18.vocab

Purpose: A keyword value reference can contain a controlled vocabulary from where it originates. This element is optional but, if given, must follow certain guidelines.

Prerequisites

• A.01.validate must be passed

Test method

The test performs the following check for each vocabulary:

• the node must contain a title at ./gmd:CI_Citation/gmd:title and should not be an empty characterstring
• the node must contain a date at /gmd:CI_Citation/gmd:date/*/gmd:date/gco:Date
• the node must contain a dateType element at /gmd:CI_Citation/gmd:date/*/gmd:dateType which contains text that equals one of publication, revision or creation.

Validating if the keyword is actually available in the indicated vocabulary is a challenge, since the vocabulary is usually not referenced by a URL. If a vocabulary is indicated that is available to the validator, then this check can be performed.
