Armando, in many cases it's not practicable because the base URI usually already denotes something else. For example, for concept schemes it is common to use the base URI as the identifier for the skos:ConceptScheme resource. If that's not so in your case then there's nothing wrong with using it to denote the void:Dataset.

Choice of URIs is 100% up to the data publisher, and there's little point in giving detailed recommendations for how to mint URIs for use with a particular vocabulary. It's not their syntactic structure that matters, but the triples that relate them.

One very simple thing which came to my mind was: why not using the baseURI (again:http://aims.fao.org/aos/agrovoc/) of the scheme as a resource and publish it as a DataSet?, much like the common practice in ontologies is to use the baseuri as the resource identifying the ontology itself. This way, I would not use any file, and I would just make the data accessible through the SPARQL endpoint. The baseuri would also return - through HTTP access, in case of a request for any of the RDF mime-types - exactly the description of the Dataset.
