Maybe try something like this in your serializer,

class ClassificationLabelListSerializer(serializers.ModelSerializer):
    lastChanged = serializers.DateTimeField(read_only=True)
    identifier = serializers.CharField(read_only=True)
    revision = serializers.IntegerField(read_only=True)
    class Meta:
        model = ClassificationLabel
        fields = ('displayName', 'helpText', 'identifier', 'backgroundColour', 'foregroundColour', 'comment', 'description', 'lastChanged', 'revision')

    def create(self, validated_data):
        return ClassificationLabel.objects.create(**validated_data)

Also, edit the save method in your models.py,

def save(self, *args, **kwargs):
    self.revision += 1
    return super(ClassificationLabel, self).save(*args, **kwargs) #
