It is possible to remove the metadata previously associated with an FTML publication.

Metadata removal is irreversible.

The following lines show how to remove metadata using the @metaAction attribute in the ft:khubItem element and an empty ft:metas element:

<?xml version="1.0" encoding="UTF-8"?>
<ft:controlFile xmlns:ft="">
<ft:khubItem type="map" ft:originID="map_id" metaAction="replace">

As the @metaAction attribute is set to replace with no new metadata defined in ft:metas, all the previous metadata are deleted.

Semantic metadata, beginning with ft: prefix, can be modified but cannot be removed.




<ft:meta key="ft:author">John Doe</ft:meta>

<ft:meta key="product" type="stringTree">Antidot|Fluid Topics</ft:meta>



If ft:metas is empty with the @metaAction attribute set to replace, product information will be deleted but ft:author will be kept.

- If the ft:metas element is not present, no action is performed on the document's metadata.

- There is no need to reupload the content to modify the metadata of an FT map.
