Yes, I have modified the code just after sending you the original email, and
the app worked, so I will continue to use it...
And about the query for getting all the tags:

select distinct ?label count (?tag) where { ?r nao:hasTag ?tag . ?r nie:url
?url . ?tag nao:prefLabel ?label . FILTER(REGEX(STR(?url),
'^file:///some/path')) }

about which we discussed some days ago: in this form is perfect, but when
some tags are selected by the user, I have to add those to it, so the new
query will select only those tags belonging to all the resources which are
already tagged with the selected ones... and I think it will become a mess
:)
So maybe I really have to find out a way to use the Query API for it, too,
because the resulting code would be more polished (in fact, it would only
need to add more ComparisonTerm objects)...
