code: function setVocabIds(index, pkg, callback) {
  	if(!pkg.tags) return callback();
  
  	if( index == pkg.tags.length ) {
  		callback();
  	} else {
  		getVocabId(pkg.tags[index].vocabulary_id, function(id) {
  			pkg.tags[index].vocabulary_id = id;
  			index++;
  			setVocabIds(index, pkg, callback);
  		});
  	}
  }
docs: we are going to assume people pass names in the vocabulary_id column to which point we need to look up the id from the name so package_create does the correct association
