How to correctly name the classes of this BEM slider?

Question

BEM

what is the correct name for the BEM classes for this slider?


Here is what I wrote, but it seems to me that it is not quite right, plus even larger classes...

<section class="goods section-outer">
                    <div class="container">
                        <div class="goods-inner">

                            <div class="goods-slider">

                                <div class="goodsMainSlider-container">
                                    <div class="goodsMainSlider-wrapper swiper-wrapper">

                                        <div class="goodsMainSlider__item">
                                            <img class="goodsMainSlider__item-img swiper-slide" src="" alt="">
                                        </div>

                                        <div class="goodsMainSlider__item">
                                            <img class="goodsMainSlider__item-img swiper-slide" src="" alt="">
                                        </div>

                                        <div class="goodsMainSlider__item">
                                            <img class="goodsMainSlider__item-img swiper-slide" src="" alt="">
                                        </div>

                                    </div>
                                </div>
    
                                <div class="goodsSecondSlider-container">
                                    <div class="goodsSecondSlider-wrapper swiper-wrapper">

                                        <div class="goodsSecondSlider__item">
                                            <img class="goodsSecondSlider__item-img swiper-slide" src="" alt="">
                                        </div>

                                        <div class="goodsSecondSlider__item">
                                            <img class="goodsSecondSlider__item-img swiper-slide" src="" alt="">
                                        </div>

                                        <div class="goodsSecondSlider__item">
                                            <img class="goodsSecondSlider__item-img swiper-slide" src="" alt="">
                                        </div>

                                    </div>
                                </div>

                            </div>

                        </div>
                    </div>
                </section>
