In the past I have imported automatically some vocabularies using rdfx/evoc and put some rdf mappings using rdfx ui. The module also made automatic rdf mappings with taxonomy terms and various fields that does not let me delete.
Now I need to clean up the mappings and reach astate of rdf mappings as it would be a fresh install.
RDF UI and other modules do not provide the possibility of deleting mappings.
What tables/fields I have to delete/alter from the database, so to clean up, without damaging the rest of the site? How I can bring rdf_mapping, mapping BLOB to defaults?
