Building a schema with mongoose

I understand how to build a schema, but I not sure how to build one for a project i am working on now. I need to build a schema for haikus, I am not sure the best way to but i was thinking something along these lines:

const PoemsSchema = new Schema({
	user: {
		type: Schema.Types.ObjectId,
		ref: 'users'
	},
	text:{
		type:String,
		max: 5,
		required: true
	},
	text: {
		type: String,
		max: 7,
		required: true
	},
	text: {
		type: String,
		max: 5,
		required: true
	}
});

module.exports = mongoose.model('poems', PoemsSchema);

any advice would be great
