With tag object you can set content type and field storage to tag, which in practice means you can add/edit/delete tags, search on tags etc. Object is just a storage option (Standard-Tags-somecolumn), you need to create fields and content types yourself - to be able to search you first need to create a content type.
Thanks. This I understood it already: I created a content type based on the TAG object with some fields mapping the existing tag table.
my concern is that neither from the article manager nor in the native tag manager can I create new tags derived from this seblod enhanced definition.
the screenshot attached here shows that there must be some TAG integration somewhere in the joomla interface but I can't find it. Hence my question about how can I create these new tags I defined in SEBLOD
