Usage

Creating a vocabulary:

Taxonomy::createVocabulary('Cars');

Retrieving a Vocabulary:

$vocabulary = Taxonomy::getVocabulary(1);             // Using ID
$vocabulary = Taxonomy::getVocabularyByName('Cars');  // Using Name

Deleting a Vocabulary:

Taxonomy::deleteVocabulary(1);             // Using ID
Taxonomy::deleteVocabularyByName('Cars');  // Using Name

Adding a Term to a vocabulary:

Taxonomy::createTerm($vocabulary->id, 'Audi');

You can also optionally specify a parent term and a weight for each, so you can group them together and keep them sorted:

$german_cars = Taxonomy::createTerm($vocabulary->id, 'German Cars');
$italian_cars = Taxonomy::createTerm($vocabulary->id, 'Italian Cars');

$term_audi = Taxonomy::CreateTerm($vocabulary->id, 'Audi', $german_cars->id, 0);
$term_bmw  = Taxonomy::CreateTerm($vocabulary->id, 'BMW', $german_cars->id, 1);
$term_benz = Taxonomy::CreateTerm($vocabulary->id, 'Mercedes-Benz', $german_cars->id, 2);
$term_ferrari = Taxonomy::CreateTerm($vocabulary->id, 'Ferrari', $italian_cars->id, 0);

With the Car Model, I can create a new instance and assign it a term for the make it belongs to:

$car = Car::create([
  'model' => 'A3',
]);

$car->addTerm($term_bmw->id);
$car->addTerm($term_benz->id);
$car->removeAllTerms();              // Remove all terms linked to this car

$car->addTerm($term_ferrari->id);
$car->removeTerm($term_ferrari-id);  // Remove a specific term

$car->addTerm($term_audi->id);

// Get all the terms from the vocabulary 'Cars' That
// are attached to this Car.
$terms = $car->getTermsByVocabularyName('Cars');

To retrieve all the cars that match a given term:

$audis = Car::getAllByTermId($term_audi->id)->get();
