Hi,
I was able to successfully export the [Tags](https://community.denodo.com/docs/html/browse/8.0/en/vdp/data_catalog/browse/tags_browse/tags_browse) and [Categories](https://community.denodo.com/docs/html/browse/8.0/en/vdp/data_catalog/browse/categories_browse/categories_browse) along with the associated elements by choosing the “**Administration**”> “**Import/Export**” option of the Data Catalog.
After importing the zip file, if the associated elements are not reflected, I would check for the following:
* Verify whether the same element which is assigned to the Category or Tag is present in both the source and target environment.
* Check whether the user performing the export is a global administrator or a user account granted with the IMPORT / EXPORT privilege.
You can take a look at the [Import and Export Data Catalog Metadata](https://community.denodo.com/docs/html/browse/8.0/en/vdp/data_catalog/administration/import_export/import_export) section of the Data Catalog Guide for more information.
Hope this helps!
