Metadata editor creates an empty topicCategory tag (dataset - rndt)

[silvia-starnini]

Using metadata editor on rndt dataset, the metadata XML is filled with empty topicCategory tag like the following:

<gmd:topicCategory>        
    <gmd:MD_TopicCategoryCode>farming</gmd:MD_TopicCategoryCode>
</gmd:topicCategory>
<gmd:topicCategory/>      <!-- this empty tag is a problem for RNDT validation-->

The wrong empty tag seems to be added :

• changing tab view to "Dataset e serie"
• adding a new topic category (the new category is correctly added but at the end also the empty tag is added)

Dear support, I've the same problem on geonetwork v.3.10.4 May I have feedback on this Issue?

It seems that the element is internally added, here the relevant log

This also happens on plain 19139 schema plugin, where this extra element is being taken care of in the update-fixed-info.xsl,

  <xsl:template
    match="gmd:topicCategory[not(gmd:MD_TopicCategoryCode)]"
    priority="10" />

We're going to solve this in the same way.

• fix b69d664: when editing the metadata, the empty topicCat will be automatically removed
• workaround f2927e5: empty topicCategories will be removed in CSW output
